WIFI problem need help!

Balur said:
Hey guys, I've been having a problem with the wifi on my universal for awhile, it just won't turn on, antenna stays off, no scanning, it's just off.
Going into the Wireless lan settings in the control panel "Wireless LAN OFF" is displayed, click "Turn on WLAN" it thinks for a few moments then returns to off with nothing changed.
Does anyone know if this is fixable? It doesn't appera to be a software issue, as it has continued on 3 diffreent ROMs... so i'm not sure how to proceed

hi @ all
this tread is a bit "past" but now i got the problem mentioned by balur.
i actually use maxstegis rom(5.2), but i also tried it with te shipped one from t-mobile.
i used google and the forum search, but i was not able to find a solution. i hope smb. can help me, because i need the wifi tomorrow!

1) Perhaps some of these ROMs are based on others that have the same problem.
solution: choose another ROM. Tomal8.2, minhanhtran, nncuong are ROMs that I vouch for that work on my maching with no WIFI problems
2) Perhaps your radio is not good
solution: try flashing another radio. I use 1.18, but many say 1.15 is the most stable. I have had problems with neither - but it may be worth reflashing your radio to make sure it is ok and stable.
Personally, I think if your original t-mobile ROM doesn't work, then you have problems with phone hardware. First I'd check other things can connect to you WLAN, to make sure it's definately the phone that's not good - or perhaps try and connect to a friends WLAN.

how can connect to a friends wlan? Quote(Balur): "returns to off with nothing changed." i cant even turn it on!
but thanks for your help!!!

I've the same problem with Tomal's 8.2. An other rooms I've tried.
The only thing I did was to change my 2Gb SD to a 4Gb HDSD

I experienced automatical turning off WiFi on Tomal 8.2 when i installed some tweaks - one to edit system settings and speed up Uni, second to disallow applications turn on GPRS - only manual turn on.
I'm not sure which of them was causing it .... don't you have something like that installed?
I'll try to find exact names of them when I'll have a while ...

Yes I had the XCPU Scalar. But now, even if I install an Original Shipped ROM, I can't turn on the wifi. I think that something is swiched off permanently, but I don't know what nor how.

[Q] Wifi & Google Maps issue with latest Valhalla Black

First: Is it just me, or is Google Maps constantly running in the background? Not only is it constantly running, but there seems to be three different instances of it running in my background. Every time I open TasKiller, there's always 3 icons for Maps.
Second: Normally my wifi works, but when I'm at school I have issues with it. My school's wifi requires that I set the 'Phase 2 authentication' to "MSCHAPV2," but when I do that, it automatically resets it to default (which is no phase 2 authentication). I've tried all of the other options for Phase 2 authentication, and every time I close the wifi options, it's back to the default option. Should I use logcat for this?

Maps runs in the background no matter what ROM you're on.

The maps always running issue can be solved by using an app such as autostarts.

I figured that it would start on it's own no matter what, but why are there three instances of it? Nevertheless, I'll try out Autostarts to have it stop coming up on its own.
Does anyone have an idea about the wifi issue?

I created a bogus wifi setup on the phone & I see the same issue; it defaults the Phase 2 authentication back to "None". I am not on Valhalla Black, either. I'm on stock 2.3.6 with bhndven's SMS kernel (3.1) so I think we're on the same kernel.
I don't want to say the kernel is the issue, though. Maybe someone else on here that is on a different kernel can try to create a wifi connection on their phone?
I'll wipe mine later and flash straight stock & see if I have the same issue. Might just be a 2.3.6 bug.

It's not anything bhundven has done to the kernel. Just tried it on my wife's phone and it's completely stock and I get the same results as you guys. After googling the issue it looks like most people were having a problem after upgrading to GB 2.3.4 and up. It looks like it goes further than our device.

Thanks for saving me some time Now the question is why.....

I wonder if its a problem with the certificates that are installed. Maybe they don't play nicely with Android?

Thanks guys for the responses at least now I know it's not just my phone. I'm visiting a friend away from home at the moment so I can't take any action right now, but once I get home, i'll try to google this a bit and see if I can find a solution.

[Q] Wifi stuck on "Saved" with Revolver ROM

I flashed from ICS Beta 1.3.1 (which was sporadic at best, use to get stuck at "Obtaining IP address") to ICS RC1 and now my TF won't even try to connect. It just says "Saved", and that it. I've tried reflashing + 3x full wipe + cache wipe and nothing is helping. Does anyone know how I can fix this problem?

Did you coldboot your tablet yet?
Try restarting your router.
If that doesn't fix it, try flashing a custom kernel.

My router has been restarted a few times and every device I have connect just fine. I have not cold-booted (that's actually something I've never done) and will look into custom kernels. Thanks!

I've coldbooted, flashed a custom kernal and reflashed Revolver 4.0 RC1 and my WiFi still doesn't work. Any other suggestions?

Yikes, at this point you should try messaging Gnufabio to try and work something out, it's probably rom based. I've never tried Revolver though.

May i ask if you have a "%" or similar char in your password?
I found that since last friday ( i flashed from Megatron to Frozn) i cannot use % as a char in WIFi passwords. Also i cannot use % in any password on the internet.
F.ex amazon account has a % in it. I always get wrong password, though it works from my laptop....
Anybody has a similar issue?
BTW, my wifi password still contains an "!" which is still working...
HELP =)
Cheers,

I solved it for me: changed to asus keybord and i can put passwords with % characters in.
Seems like there is an issue with the android keyboard? Or is it just me?

My key phrase is all letters and numbers. I'm going to continue to try different kernels, but if nothing changes, I'll just have to try a different rom.

I've now tried several different kernels, super wiped and flashed the Revolution HD rom and my wifi is still stuck on "Saved". I'm out of ideas.

Here's a novel idea, buy a new router. I chucked my 2 year old Belkin because my wife started complaining about her iPhone not being able to connect. Got a brand new somewhat expensive Cisco Linksys router and voila, everything connects like a dream.
Thanks to all who tried to help.

[Q] Hotspot on phone won't connect to android tablet

I'm not sure where to put this so I'm going to post it here but if it's in the wrong spot please feel free to move it, Mod.
Ok, I have a Motorola Photon Q 4G LTE (downgraded to 3G, no 4G in my area) running Android 4.1.2 that I use my Hotspot internet off of. I have connected it to just about everything, computers, tablets, and other phone and it has always worked perfectly until now. I got a Visual Land Prestige Pro 7D tablet running Android 4.1.1 for Christmas and for some reason my phone's hotspot won't connect to it. It says it is connected but when I go to use the browser or any app that uses the internet it never loads or doesn't work. Sometimes the signal even drops out and reconnects but never actually works. I did some research and it sounds like it might be an IP address conflict but I am not sure how to fix it. Some sites suggest downloading another tether/hotspot app so I tried a few. Some revert back to the original hotspot setting on my phone, which of course did me no good, and some just plain did not work, they did exactly like my original hotspot, connect but won't work. I have pretty much figured out that it has something to do with my phone's hotspot since my tablet works perfectly fine on other people hotspot or wifi internet. Can someone please help me figure out what is going on?! Thanks in advance!

Are you on the stock ROM? Seems to be from your post.
You've tried using the built-in tethering feature, as well as some 3rd party software. Most of the 3rd party programs will create an 'ad-hoc' network which typically only other computers can connect to. There's some threads around here that discuss how to remedy this on stock. Search around.

Yes I'm still on the stock ROM the phone came with. I have tried the built-in and 3rd party apps and neither is working. I'm really not sure to look for. I have tried a few different things including changing the IP address in my phone hotspot settings and nothing works.

I just tried to download the ISWAT Tether Unlocker but I noticed that it is only for rooted devices, I'm not rooted, and I really don't want to root it. Any other suggestions?

A phone w/o root is less than half phone.
BTW you can try foxfy or pdanet, the latter works surely, but at the price of a client installation on the PC side, and is USB/BT only.
I haven't tested the former

I have rooted my phones before but I like this phone the way it is for right now and I just don't want to go through that long process of rooting it.
I have tried Foxfi, it connects but like the others, the browser and app never load, but I can connect to any other wifi or hotspot and they load fine. From what I have heard Foxfi and PDAnet are the same, they even have a combined app. I have done some more research and it looks like maybe my phone or tablet, which ever one, is running adhoc (?) and either one or the other can't use that. Does that sound about right?

PDAnet and foxfi, are two apps sold by the same company, but are all but the same thing.
PDAnet is a 10+ years old program, is older than android, and is an absolutely proven SW, working on multiple platforms either on server and client side.
FoXfi is a relatively new program that manages to work on a great number of devices, but that is not guaranteed to work on any device.
If foxfi doesn't work on PQ, I'm afraid there is nothing you can do w/o rooting the phone.

Install TWRP, it will automatically offer to root the device after booting to recovery and then in recovery restarting to system.
Otherwise follow this guide to install CWM / SuperSU.

Sorry for the late reply. (time zone is our enemy
BTW given arrrghhh already replied, I can only add to avoid confusion to follow the linked thread about CWM, but replacing the CWM part with TWRP.
The latter is more newbie friendly and, will root automatically the phone, and will also block the function that restore the original recovery on the first boot.

Basically you need to install the drivers and get ADB working, before doing anything else
Once you have done that step you can unlock your phone, using the instructions provided on the CWM thread, and in the related motorola website iself.
Then is flashing the TWRP is pretty easy, you just need to start your phone in fastboot mode, connect your phone the the pc, then issue the command
fastboot flash recovery twrp-something.img
(replace the last part with the real name of the file downloaded from the TWRP thread.
then reboot in recovery once (is mandatory to not reboot in system the first time) and when you will exit the recovery environment, it will ask if you want to root your phone.
That's all
This is a quick walk-trough, I hope you can understand that I can't detail every single step more, if and when you have doubts, just google a bit and ask for the definite problem you may have, here.

[Q] LG Lucid 2 VS870 wifi saved but not connecting

I recently got an LG Lucid 2 (VS870) which is running android 4.1.2 software VS7011A. I have also tried it on VS87010B. When i go into the wifi settings, I can see and add networks, which then say "saved, secured." it does not try to obtain an ip address or anything, it just says it is saved. It worked fine for about a day, but then stopped connecting.
I have rooted it with framaroot 1.9.1 (apk attached), which installed with no problem. I have used CWM touch recover, which does not need flashing, by playfulgod (apk attached)
It has this problem for all wifi networks i have tried, and resetting the router did not help. Other than initially rooting it, i have not changed anything along those lines. I have looked all over the internet with no successful solution, and any help would be appreciated.

i did this exact same thing
seems the defualt mac address is overwritten when the kernal is flashed with the unlocked one, once done, nothing fixes it, ive tried, it seems the unlocked kernal messes with the phone somehow for some people. but i found a work around, you have to install an app called macChanger and spoof a random mac address you must do this once in awhile or at every reboot, ive found no way to set the mac address so it seems we are ****ed, best bet it to just keep it as a nice mp3 player or a movie phone

Seems to work

I revisited this issue, and I found what appears to be a solution. I tried your suggestion, and seeing it worked, decided to mess around and see what i could figure out. I edited the mac address on the last line of /data/misc/wifi/config
and after a couple reboots, the address i entered seems to stay as the device's mac address and wifi continues to work.
I attached my edited version of the file

works Mac address issue fixed, needed to reboot at least three times
