WPA Enterprise Auth - confirmed working

WiFi on campus here uses WPA enterprise auth - good. I was shocked when I saw that the phone seemingly didn't support it. Network didn't even appear in the list, and Add Network only supports WPA Personal / WEP. How Apple of them. But WHY? It's wpa_supplicant behind the scenes.
I've been using campus wifi successfully for a few days now. It seems to integrate well enough - the wifi settings menu doesn't seem to break at all, the enterprise-authed network and status are listed correctly including the 'lock' icon, etc.
These instructions are slightly modified from being specific to the particular university (posted locally too, you see). If you can rub some braincells together, this can be adapted. The parts regarding a certificates file may or may not be needed in your setup, for example.
* Get a root shell
* cd /data/misc/wifi/
* cat wpa_supplicant.conf
* The existing supplicant config is displayed - copy and paste it into a text editor (the beginning bits are important, as are your existing networks)
* Paste in a working wpa_supplicant.conf section for your network at the end
* Fill in username and password in the new section. Replace the path for cacerts.pem with /data/misc/wifi/cacerts.pem
* Save the new config onto the SD card
* Save the cacerts.pem (same site) onto the SD card also
* On the handset: In the settings/storage menu, disable the SD card for USB storage (otherwise, can't access it from the shell)
* rm wpa_supplicant.conf
* cp would be used here normally, but it isn't in the stock image: dd if=/sdcard/wpa_supplicant.conf of=wpa_supplicant.conf
* chmod 666 wpa_supplicant.conf (Warning! Readable/Writable by EVERYONE! Use 664 such that only root can write it if you want, but this will possibly disallow changes by the settings app - if chown was available, ownership would be reverted back to wifi:wifi)
* dd if=/sdcard/cacerts.pem of=cacerts.pem
* chmod 444 cacerts.pem (needs to be readable by wifi user)
* The network should appear in the wifi menu and connect if you enable wifi. Reboot if not maybe?
Problems:
* Permissions are a bit wonky due to lack of chown. The process would be cleaner with busybox installed (possible with root), but this process is written to work on a stock RC29 handset.
* It will almost surely fail following an update. Try not to give up root before the WiFi UI is patched
* Maybe there's a reason that enterprise auth is absent from the settings UI
* WiFi settings page may or may not break. WiFi settings page may or may not undo your changes.
A quick troubleshooting tip: if you've dealt with wpa_supplicant before, note that wpa_cli is available to root. Helpful to diagnose any issues that crop up.
Enjoy.

How Apple of them. But WHY? It's wpa_supplicant behind the scenes

I suspect it's because the majority of consumers only access wifi networks secured through psk or mac-address. iirc my university used mac-address too. Not sure if that's changed by now. In any case, I wouldn't hold my breath for official support on the G1. Maybe on some future Android device with enterprise in mind.
Anyway, good tips and good first post. Welcome to the forum

busybox has chown

WPA2
Can I ask a question?
The SSID for your campus wifi is not broadcasted, correct? if this is true, then it won't show up and the only way to get access is to add it manually.
Now when you go to add it manually, did you try to change the type of security before you flipped out the keyboard? Just wondering since WPA2 is clearly seen if you have the keyboard in and if you have it out it looks like WPA2 isn't an option but if you try to move the security box with a swipe up with your finger, WPA2 will be shown. I haven't had a single problem attaching to my home or work network using WPA2 PSK since RC19 and beyond.

Yep, busybox has chown - which makes the whole thing cleaner and safer. My instructions were written originally with no assumptions as to previous modding, incl how to get telnet.
The wifi network here does broadcast, but is filtered out due to "unsupported" security. Add network lists wpa2 personal but not enterprise.

I modified my wpa_supplicant.conf file using your instructions and it worked!
Thanks!

Because there's a substantial amount of UI work that needs to be done for WPA2-Enterprise compared with the relatively common WPA2-PSK.
My advice? If official support is something you'd like, go write it and submit a patch to the Android devs.

Not working
I can't get this to work. It says "failed to start wifi".
My non-enterprise wifi won't even work now. It connects but apps say network error.
I am trying to connect to my university's wifi that is "Secure 802.1X authentication and EAP-TTLS with PAP inner-authentication (anonymous)"
Can anyone give me an example config for this? It doesn't use a certificate.

Confirm that the permissions were set correctly on wpa_supplicant.conf
I'm sure you can find an example for that particular setup online somewhere.

try this:
adb shell
cd /data/misc/wifi
chown 1010:1010 wpa_supplicant.conf

Worked for me too, but the connection was really unstable. I've added the option bssid to wpa_supplicant.conf to prevent roaming. Now it works really well on my desk, but I haven´t tried the rest of the company.

need help connecting
I'm trying to connect to a campus network, I see the SSID detected (as following), and It tries to connect and aborts by itself.
my wpa_supplicant.conf shows this:
network={
ssid="Techwifi"
scan_ssid=1
key_mgmt=NONE
priority=2
}

hey guys,
will this also work with WPA2 and EAP/TTLS with PAP?
or do you know when this feature will be integrated?
thaks a lot

Yes, I have it working.
Code:
network={
ssid="ssidname"
scan_ssid=1
key_mgmt=WPA-EAP
eap=TTLS
identity="user"
password="pass"
phase2="auth=PAP"
}
Note: It seems to drain my G1's battery pretty nicely and it starts to get hot after being connected for a bit. Also, my G1 added disabled=1 to the end of this network after the ADP1 v1.1 update, strange.

Thanks happyface_0,
so I will have a few minutes online.

Is there a way to alter your wpa_supplicant settings on an unrooted German G1 , or how can i downgrade and then alter the settings, does anyone know?

I'd love to know that too, i really want to use wifi at work.
Can we do anything to help you help us?

Maybe someone with a US RC33 can look if the WPA 2 Enterprise support finally made it into the gui of the G1 , then our problem would be solved ,
can´t find something on the net which says that WPA 2 Enterprise was part of the Internet .
So please can somebody look up his or her connection settings for wlan and tell us if WPA 2 Enterprise is available now?

Neither WPA-Enterprise nor WPA-2 Enterprise are available yet without actually editing the wpa_supplicant configuration manually, even on RC33.

Hmm thats pretty sad, is it actually possible to write a program which can edit the Wpa_supplicant file so that we can manually insert the settings we need to get WPA 2 Enterprise working , even on phones without root?

[Request] Patch for enabling ad-hoc wifi networks in ROMs

Devs,
I use my office LAN connection as a net connection for my 32a Magic phone by creating an ad-hoc network and sharing the LAN connection - basically the opposite of WiFi tethering. I have been successfully using that by following the instructions at http://modmygphone.com/forums/showthread.php?t=22681 (which is applicable for all android phones, I guess). Ad-hoc networks are not enabled by default. The procedure requires changes in the "system/etc/wifi/tiwlan.ini" and "/data/misc/wifi/wpa_supplicant.conf" files.
Making these changes with the Magic touchscreen keyboard is quite tedious.
My request is for ROM developers to:
a) Enable this in their ROMs by default (I guess everyone would benefit from enabled ad-hoc wifi); OR
b) If someone could create a patch that overwrites these files with modified variants that is easy to apply over ANY other ROM (would be useful for those who tend to change ROMs often )
I searched for a solution and posted a question in Sapphire General, but no one chastised me/answered, so am reposting here (on second thoughts, I should have posted here in the first place).
Thanks!

post the modified files here, so ppl can create an update file.

+1 - it would be lovely to have a patch for that!

This would be great for someone like me in a country that charges a lot of money for 3G. Hope it gets implemented.

Files to be changed
I have attached the two modified files:
1) tiwlan.ini (remove .txt) needs to update the one in /system/etc/wifi/
2) wpa_supplicant.conf (remove .txt) needs to update the one in /data/misc/wifi/
This will require you to create an open (no encryption) Wifi network called "androidwifishare" (case sensitive, without the quotes) and share your LAN connection.
Note that overwriting wpa_supplicant.conf will make your phone forget all stored Wifi networks and their keys

Why don't you just "adb pull", edit on the computer, and then "adb push" the modified files back into the cell phone ? You should be able to do this into any rom, with no need to package this into an "update.zip"
I don't understand anyway why should you create an ad-hoc network .. wireless access points are very cheap, like starting from 30$, why one would use his PC and a dedicated wifi card to create an ad-hoc network nowadays ?

Because, it's easier to have a wifiupdate.zip that can be stored in the SDCard and can be applied at any time after changing a ROM (without the need for looking around in a PC) using Amon_RA's recovery

a) Not everyone has a WiFi network _in office_ (please refer to my original post)
b) Its a good way to avoid network data costs (which are high)
c) You get good transfer rates, much better than the mobile network (no 3G here)
As simple as that

i know this thread is kinda old and "dead" but i tried this with my girlfriends magic
works but as soon as the magic connects to the wifi of my G1 it reboots
strange thing
i noticed that this also happens with the free Wifi spot from Mcdonalds at our city
what could that be and why won't it happen when the magic connects to my access point??
thx for help in advance

EDIT:
Magic ROM: Cursorsense 1.2.6.1
Device: HTC Magic PVT 32A

Could we get a new user sticky guide?

IF this device is sold in the thousands on Black Friday, there will probably be a "couple" or more people interacting with this forum. Perhaps the following would be handy:
1. Start from scratch guide (CW and non-CW methods)
2. Pros and cons of CW vs non-CW (assuming non-CW will be an option with the OEM update based roms)
3. Survival kit if in boot loop
4. Links to roms & add on apps (with dates of when updated)
If Roeb, Roth and others could consider a guide and approach it from a general audience level (not clueless, but not a root vet either), this could save a LOT of posts due to questions related to how to do it or fix it when doing it wrong.

I thought i was already doing that.
If a user can't do a firmware update, then they might as well stick to TnT stock. I think the biggest issue they'd face is the infinite reboots, since the fix sometimes requires cwm or even nvflash.
EDIT: I have a general FAQ in tegratab - - I'll port it over.

Good point
BTW, anybody able to get the Gtablet to work with either USB or wifi tethering? I have struck out with both using my Incredible, which works fine with my laptop.

WiFi tethering worked for me using my Nexus One. I had to do nothing special to get it to work. At the time I was running Zpad 0.2. I'm on Cyanogen Beta 2 right now, but I've been running on my home WiFi. I'll try the wifi tether and report.

Does the Incredible (like the Droid1) only provide Adhoc (vs. Infrastructure/AP) Wireless tether???
If so, then you will need to make the 2 wpa_supplicant.conf file edits SIMILAR to what I described for the ZT-180...
http://www.slatedroid.com/zt-180/69...o-static-ipaddr-required-edit-files-once.html
I say Similar, as the ctrl_interface=wlan0 on Gtab vs. =ra0 on ZT-180... but otherwise it's just edit the same 2 files the same way...

Not sure, but I do know this works with my M11X, but I mainly do USB tether, which I am guessing does not work either (since I could not get it to work on the Gtablet). Not had to mess with settings before...
Dang, if I can not fix this, my love affair with the G will be but a short fling- need to be able to tether.
I can not even get the blue tooth to pair.
I was so focused on the PSX gaming and web & Flash at home, but never figured in a million years that I could not connect to my Inc.
There is a bunch of options in the app I use, simply called "Wireless Tether".
The Gtablet will sometimes say "network available", but does not show it (probably work's, but even my Inc will show the network here). Then again, I turn my Inc off and the G still says "network avialable", so go figure.

All you need to know is the SSID... for your phones tether... I believe I used what was the default for the Droid1 which is likely the same... you can enable Wifi Analyzer on the GTab to determine the SSID when you enable tether on the phone and that should be the only thing you need to know for Adhoc with Not change of settings to the phone... then the 2 file edits... my example locks my 2 home networks and my Adhoc tether configured and overwrite/updte disabled so when I temp find roaming nets I can cannect but Not sane them for later but that works just fine for me... so I'd say copy the networks you have saved Now in your /data/misc/wifi/wpa_supplicant.conf and use them to replace my jtb* networks... and try just using my adhoc network as is, with same globals I show in the examples...

Are there not sub-mod's that can do this stuff on this sub-forums? If not, this will be really annoying trying to get a sticky.

How can I do both at the same time? Using same device (using Inc for wifi analyzer and wifi tether at same time should not work)
Gtablet does not see my phone, but connects to my home system and see area networks fine at home Traveling on the road is the killer for me
I am not understanding the file edits you mention. Is there a highlight of what parameters to edit, or is this all new script?
Update.
Even using PDAnet is a bust with Bluetooth. The devices pair, but no connection.

Yes, my example does both... I can turn on tether sitting in my home lab and sometimes the gtab even switches from my weaker AP to the phone adhoc... usually I just toggle wifi off/on to get it to switch... if I stop tether it jumps to my AP...
Really the only params that are required are the ones I set in the example...
These global params would be same for you...;
# Globals
ctrl_interface=wlan0
update_config=0
ap_scan=2
This Adhoc specific network would be same for you I believe just verify your ssid all else is definitely same as default in tether from market...;
network={
ssid="AndroidTether"
scan_ssid=1
mode=1
key_mgmt=NONE
priority=30
}
Then paste what you currently have saved for networks you frequent below these like my 2 home AP nets, so your currently saved networks would differ here...;
# Lab default
network={
ssid="jtbnet-lab-wireless-3"
key_mgmt=NONE
auth_alg=OPEN SHARED
wep_key0=16593b8024
priority=20
}
# Home default
network={
ssid="jtbnet1"
key_mgmt=NONE
priority=10
}
Once you have the /data/ short version of your file like above... just also paste that piece to top of the /etc/wifi sample file that the tablet uses as a starting template and comment out the 2 differing settings further down in that original template file...
# update_config=1
# ap_scan=1
And you should be good to go to work on your current saved local nets as you can now, plus your Wifi Adhoc Tether.... the update_config=0 says don't overwrite these files with any found nets, or change any of my default settings... , but you can still roam and connect... just won't save any of the temp nets you find roaming as they will change some of the critical settings like ap_scan=2 if you let them update... you can always manually edit and change or add locked down nets later...

Most likely an android issue.
If you are using barnicle or wifi tethering your laptop will see it fine, the laptop can normally see what is called Ad Hoc networks.
Android cannot (unless tweaked?) normally see an Ad Hoc Network, they need what is called infrastructure mode, which is what a normal wireless router transmits at (unless modified to something else), so the GTab will not see your incredible's signal like your laptop will.
I am using the droid X and the 3g hotspot app, the 3g hotspot transmits in infrastructure mode by default and the gtab sees it fine.
There are hacks to get 3g hotspot for free, but I would not guarantee Verizon can't still see a connection and charge you, use at your own risk.

i'm connected to my incredible right now, it works fine using wifi tether from the market.

I am still having no luck with Incredible and getting the Gtab to see it. No problem with my router at home.
I am using TnT 1.02, wifi tether app and even tried the binary file add on from the EVO.

1) This thread seems to have turned from sticky to tethering -- different but extremely useful info. May I suggest the moderators to move the relevant posts to a new **sticky** thread?
2) Speaking of tether: Have anyone managed to do USB tether with the g-tablet? This could very well be the key factor in my decision to keep or return the g-tablet, and I'd be most appreciative for any help and advice from the advanced users here.
Thanks!

I have tried everything software likely, but still no wifi tether being seen by the device. I can activate hotspot and the Gtablet sees it and ask for a password, so at least the G can see my Inc- just not in straight wifi mode. Does not see it at all and I do think it is the ad-hoc issue. Gtablet not seeing it for some reason.
Could it be due to having TnT lite 1.02? Perhaps the people having luck are using Z-Pad .03 or CM?
Wonder if it is possible to create drivers for USB tether?

Here is what I had to do after the newest dec 2010 update
#
#
# Connecting your viewsonic gtablet to your Ad-HOC wifi
#
#
adb pull /system/etc/wifi/wpa_supplicant.com
cp wpa_supplicant.conf wpa_supplicant.conf.orig
[Edit WPA_supplicant.conf]
ap_scan=2
network={
ssid="YOUR-SSID"
scan_ssid=1
key_mgmt=NONE
mode=1
priority=99
}
{YOUR OTHER NETWORKS HERE}
adb push wpa_supplicant.com /sdcard/wpa_supplicant.conf
use androot or root explorer to delete the current wpa_supplicant.conf file and copy the modified version to /data/misc/wifi/wpa_supplicant.conf
chown the wpa_aupplicant.conf file to owner wifi group wifi (ie #chown wifi.wifi wpa_supplicant.conf)
[notes]
Your ad-hoc network should be the first in the list as outlined above. make sure that the priority is set to a high number.
when enabling your teather on your phone you may need to disable the wifi on your tablet then reenable. wpa_supplicant will always attempt to
connect to the first network with the highest priority first so it should connect right up. If you have problems you can use logcat to debug.
you will see wpa_supplicant getting enabled and if there are any errors you will see it there. You should not need to set the update_config option
but if you have problems with your conf getting overwritten you can set update_config=0 and this will not allow wpa_supplicant to update the config.
The only downside to that is that you will not longer beable to save new network blocks to the file, You can still connect it just will not save them.

I just loaded TNT 3.0 and the supplements yesterday. I jus tried the Wireless Tether app from the market on my Droid 1 and my G Tab sees and is able to connect.

[Q] WPA Enterprise with PEAP and MSCHAPV2 Using wpa_supplicant.conf

As a point of reference, I am using a rooted HTC G2 running GingerVillain 1.5.
I have been trying to manually connect to my University's wifi (UT of Arlington if it's any help) The Xpress connect app they recommend does not work as it does not detect the network or something or rather. I don't want to mess with it anymore as it would be better to have the settings OS based than app based unless there is no other way.
So, I tried to set it up manually according to what my computer had set up: PEAP with MSCHAPV2. Android only offered "none specified" for user or CA certificates. It acts like it is going to connect, then promptly disconnects.
I think my problem is similar to this topic which was resolved: http://forum.xda-developers.com/showthread.php?t=576407
However, whenever I pull wpa_supplicant.conf and change anything, Wi-Fi won't start on the phone. Is there something else I need to do to get a modified one to work? I'll probably still have to play with some settings to get it to actually work with my university.

Ok, I found this topic http://forum.xda-developers.com/showthread.php?t=692254 which fixes the wifi crash when rebooting after modifying wpa_supplicant.conf I'll have to see if I can get the network to work next time I can go to school.

CMD for ipconfig /release , ipconfig/renew ??

My problem again is that i cant connect to a second wireless router(no password needed for second router), the 1sth router its password protected (@ my work) ,then i come home and i cant connect because the IP from my work its not gone and theres no way to release/renew
I want to know if theres an app to emulate CMD like in windows (and not a computer needed to do it),i want to do it on my tf instead (dont tell me "turn off/on your router " please, i wont be asking on mcdonalds or burguer king if they can turn off/on their router )or any other place if they can do that so i can release my ip and get a new one
Thats what i want to avoid , so if theres some way to release /renew my ip (and no computer needed) then that will be great
I have revolver rom installed , but this PROBLEM was even on the stock rom ,so is not the rom or the 2 routers, my wifes ipod 4th gen connects right away and always renews ip at any place
Please help me
Thanks in advanced

You can use terminal emulator for "CMD" window.

Just turning off your tablet will reset the wifi and it will scan for a new access point. Leaving the area of the AP at work should cause it to scan for a new one too. If you have hard coded a static IP address in your advanced wireless settings, pick up an app like WiFi Manager from the market to allow you to have multiple profiles and switch between them.

Both are DHCP enabled, so i dont know why it wont release it from previous routers , ive tried turning off/on both routers and tablet aswell and the problem persist.
With wifi manager i can make my TF to "release", or forget the las ip ?

Maybe I don't understand the problem, but can't you change wireless connections in the settings/wireless menu? Tap on the new connection?

i can acces my tf options to see what connections are on range and i can connect aswell, but the old ip form work wont dissapear and i cant acces internet or any other web content because i dont have a valid IP and there no way i can get rid of it
so i was asking if theres some way/app/etc etc to get the new ip working from my home router(not password protected)
but i think thats not the problem(open router), mi wifes ipod can connect everytime she gets home, its TF problem

If you need to get a new IP, turn on airplane mode, then turn it off. Simple as that. You're seriously overcomplicating this.

i have not tried that, i will take the TF to work today and se if that works
on a side note; im not overcomplicating anything, im trying to get help for something i dont know, im just a new TF user
thank you for the advice and i hope it works

Also, just in case, you may want to check that you don't accidentally have a static IP set on your device. Sometimes its easiest to avoid problems by simply deleting the network profile from your Transformer (or "forget" the network in Wifi Settings), and then attempt to re-connect again fresh.

Its set to DHCP so i know thats not the problem, i guess the problem rely on the routers, maybe i need to add password to my home router and see if keep getting the same problem, but as i said before i will have problems on every open wireless network maybe

As alluded to, the work IP falls out of range and hunts for a new AP.
Do you have MAC filtering?
OT: Why do you have an open home net?

i know it have to look for a new ip, but no its not doing it on my home network, thats why im having problems
as i said before, what am i gonna do when i try to connect to another open network ?? (ask them to turn off/on their routers , ask them to put password)
i dont know if this only happens with my router, i will try all the advices when i get home tonigth and see what happens

It’s (most probably) not the TF.
My work has both Open/Secured APs. It connects to the Secured as soon as it’s in range/awake, unless I manually hook it up to the Open. Same at Secured home, it connects no-mess/no-fuss.
How many Open nets do you ‘see’ at home?

just my network it's open, but my wifes ipod can connect/disconect as fast as you say with you network, it's just the TF not getting the new IP everytime i get home from work.
i was so freaking mad 2 days ago so i did a full wipe, that did the trick , i didnt have lot of apps that's why i did it , but i dont want to do it again and get all my apps lost one more time

nop !!!
none of the above advices worked , im so sorry for the guy saying i was overcomplicating this, and no , the airplane mode dindt solve it either
so i dont know wth can i do , the problem again is that i cant get a new IP, my last ip it's still not released (not even with airplane mode) , turnit off/on the device and tablet wont solve it either
i did the test with my wifes ipod (took it work then comeback)and it works as it should, just the TF doesnt work
so if i can do it with with terminal emulator (to release/renew IP) i will appreciate the step by step guyz
thanks in advanced

If you're using DHCP, under GNU/Linux the way is to launch the terminal emulator and run
Code:
dhclient -r
and then either restart the network interfaces (different between distros) or to run the DHCP client on the interface (in my tablets case, probably 'dhclient wlan0' without the quotes).
BUT!!! This being an Android tablet rather than a standard GNU/Linux system, has no dhclient program as far as I know. I have access to ifconfig, dhclient, etc by way of having Debian stable programs running in a chroot.
You might try disabling WiFi, forgetting the network, and reconnecting to it. The last router I had also had a way of getting rid of leases manually, either by telling it to tell the client to FO or deleting them all.
EDIT: Give or take specifics, I think the TF101 (or at least Prime) has dhcpcd. Try
Code:
dhcpcd -k wlan0
dhcpcd -n wlan0
to release and then renew. No promises if that will do jack though. You might also just try running 'dhcpcd wlan0' (without quotes).
For terminal emulators, go to the market or check if your ROM has one (Prime does).

You really shouldn't have to go through any of this stuff. I'd say the system is borked, maybe the hardware, maybe the software. You could try flashing a new version or just take it back, show them you can't connect to their network and get a replacement. It really works as easily as we say and as easy as the wife's ipod. I would take it back or send it in for repair, I think you have a broken system.

well i cant do that , i bougth it from ebay , i dont think its the TF itself, maybe the router (but the ipod works :S )
i will try and see if it happens on some other open network, or just replace the modem
