Wifi problem!!!

I have the new XDA terra (HTC herald) with original O2 WM6.
(btw - mostly similar to wizard - registry and all other)
And you may believe or not - the registry is set to
HKLM\Comm\TnetWln1\Pars\HTCPreloadWifi = 1
I set it back to 0 to get more Ram.
AND you have to push 2 times to get Wifi activated by commanager.
SO IT IS NOT a cooked WM6-Rom problem. Even with a real WM6 ROM i have to set the registry to 1 or I have to click twice.
Best regards.

good. one less reason to blame cookers.

Fast as wizard. Much thinner. Better keyboardslydeout = one handed possible.
BUT less ram - 23 after tweaking.
Benchmark nearly the same as with Core 2.0 on wizard. But perhaps someone is trying to port it to wizard??

Is VOIP enabled?

Better yet, can we get a registry dump?

By default it is disabled. but you can get it back by installing WM6Voip.cab.
ANd when i got manged to cid unlock and backup rom. i can share the os if you want.
But first of all I wanted to share the info that wifiproblem is not cooked-rom related.

Until recently, I kept thinking it was an issue with connecting my Wizard with WiFi (which was always the case the entire time I've owned it). About a month ago I upgraded to WM6, where WiFi did seem to work right after a ROM upgrade, but then after a while wouldn't connect to my home network. And then while fiddling with the settings on my router, it would work, but again for just a couple of days then stop. What I realized was that for some reason, my wifi would work every time I reset my router.
And I just tested it before posting: Not connecting via wifi to my home network. Reset my modem, and I connected instantly via wifi. This might help some people, maybe not everyone. But this also may support that this is not ROM specific (and I'd guess this might also have been the case on WM5 when I had that installed).

Same probelm...my wm6 wizard sees my ad-hoc network and two or three other networks fine...while connects lik eonly once to other networks and then decides it doesnt want to reconnect whenever i want to try it again (including my campus wifi sniff sniff) .... Didnt have this problem with wm5...i can confirm this issue with tnt 4 , tnt 5, tnt .1437 stable challenge and xm6 r3 ... Any fix anyone ? tried removing wireless g using registry mod ...

T-Mobile SDA (US) [HTC Tornado] WiFi Issue

Upgraded today to WM 6.1 by illi and rickwyatt using kar hoe's guide (great job btw very clear instructions ). I am wondering if anyone is experiencing issues with WiFi connectivity. I do not pay for a data plan and WiFi is very important to me. I tested today with my home access point and it seems that I never pass the "Connecting to Network" stage on the "WiFi Networks" page. It'll flash my AP's MAC address for a second or so, but no actual connectivity. I tried connecting via WAP-PSK security, WEP security and even no security.. all to no avail. WM 5 had this problem when AP's had low signal (it would flash the MAC/SSID and then move on to the next network), but never to the point where I could not connect. Also, I notice the WiFi icon shows as a tower with a halo and the three dots (/°\...) while it's trying to connect. As soon as it flashes the MAC/SSID the icon turns to a dead tower (/\). I was wondering if this is a known issue, and whether anyone has experienced and/or fixed this. Please advise... Thanks in advance
P.S. Excuse the crappy ASCII art in trying to get my point across. Pls let me know if you need more info.

I know that for my wep secure home network - I needed to add the phone to the network before it would be accepted. Just knowing the wep pass code was not enough
The phone would just loop trying to connect with no luck.
Not sure what software you are using on your network / wireless router - but this may be the issue.
Good luck

I normally use WPA-PSK encryption on the network. Its a linksys wrt-54g router. It runs in b/g compatibility mode. I even tried to connect w/o security period. It kept dropping after flashing the MAC/SSID.

well here's an update. i an still having issues with the wifi but i decided to spring for the data plan. it's only $20 us on top of the phone bill. i figured thats not a bad deal since internet is so important for me. i'm actually sorting this on my sda.

I do same as far as wifi (no data plan). I see you got one now btw, gl.
I use same rom and I got no problems with wifi, maybe you need radio update or something simple as that.
On my home network you need wep key and mac address added on my router in order to connect (just a thought); I use linksys and can post more details on this with pictures if needed.
Using wifi and Devicescape ain't that bad for me.
PS
I had to reply just so others who didn't try this rom know its not the rom issue about wifi - I LOVE THIS ROM

hmmm... devicescape, you say? yeah that's definitely worth checking out. i'll play around with it at some point. you are totally right though, the WM 6.1 rom is awesome and I encourage anyone who is still running Windows Mobile 5 to go ahead and upgrade. Karhoe's guide is a very concise way to make this happen. i was actually looking to get a new phone prior to upgrading. i was thinking about getting the HTC Kaiser (TyTn II) although I was put off by the issue where it was released lacking hardware acceleration support for its ATI Imageon graphics processor. I haven't had a chance to play with the wifi on other access points yet, so perhaps this issue was specific to my home router.
P.S. Thanks for your reply!

Can you link the thread for the exact ROM you used. I am getting a Tmobile SDA soon and want to upgrade it to 6.1, just want to make sure I used the right rom for that works with the SDA as there are multiple threads/roms posted one by illi and another by ricky.
Appreciate it! Thanks.

Att Fuse Problem

Hello Everyone,
I just received a ATT fuse and for the life of me I cannot seem to get the WIFI to work. I've had the tilt and the 8125 previously and I tried duplicating settings to no avail.
Are there known issues with the WIFI on this phone?
I can connect to my WEP enabled wireless router, but opera and IE fails to connect and just keeps giving me errors. This is what I have read and what I have tried:
Setting to "work" instead of "Internet"
I've tried the cab files posted in another thread to disable ATT proxy
I'm a little lost in what to check. I did follow everything I've read here that came up in "WIFI" search. I have not unlocked the phone nor flash a rom.
Could someone lend a hand?

Sign up for the att media program...its on the attwireless site

This is a bit drastic, but an easy potential fix is to flash another ROM (after flashing Hard-SPL of course). AT&T often adds a bunch of unnecessary crap to their ROMs, which may interfere with normal functions. You could always flash the AT&T ROM back if you'd like.

Hi Animexi80,
I already have a data plan. The problem isn't with Media net, it is with the phone's built in WIFI.
Trancecoder,
Really, that drastic of a step.. Do you know of a rom that fixed a WIFI problem?
Thanks

Honestly, I never even gave the AT&T ROM a chance, so I was unaware of Wi-Fi issues. Pretty much any ROM should work. If you flash a Fuze-specific ROM, you may want to run the CAB that disables the hidden AT&T proxy. If you flash a generic Touch Pro ROM, you'll likely need to run a CAB that fixes the keyboard layout.

Ok, I suppose I will give it a go.
If I may ask, would you tell me which rom and radio you're running. It would help rule things out it it doesn't correct the problem.
thanks

What is the "hidden AT&T proxy?"
I just got an AT&T Fuze and after enableing wifi using the wireless manager, had no trouble connecting to home wireless networks with various security configurations (WEP, WPA, hidden SSID, etc.). Of course if the access point has the MAC filter enabled, the Fuze MAC address must be added to the allowed list.

I'm running an older PROven ROM, version 1.03. I'll be upgrading soon, probably to NATF's ROM. My radio ROM is 1.08.25.20, but (1) the radio ROM doesn't control Wi-Fi, so it's moot, and (2) it has not had very good battery life, so I'll downgrade back to 1.02.25.28 tonight.

It's a proxy setting, separate from the normal one under Connections, that is hidden. It's used to make things such as Cingular, er, Cellular Video work.

This is a bit off-topic, but FYI, anything below WPA/WPA2 cannot be considered secure. WEP can be cracked in minutes, hidden SSIDs don't make APs invisible, and MAC filtering is useless (except with WPA/WPA2) as anyone sniffing traffic can see client MAC addresses in the clear.

I have found that sometimes when I have both a "data connection" and a "wi-fi" connection that they phone seems to not lock on the wi-fi but tries to use a weak data connection so try turning off the data connection and see if that fixes the problem. Also give a soft reset a try as well.

Surprised by how few ppl are having wi-fi issues. I've tried about 6 ROMs now and have the same problem with everyone (guessing this proves its more of a hardware vs software issue)
I can locate and connect to a wi-fi network but no data transfers. I have to continually disconnect/turn off/reconnect over and over and finally I will get a connection..but if unit goes into sleep for a few minutes...I have to repeat.
Very annoying...no one else is having wi-fi issues?

Hi Everyone,
Sorry I haven't reported back sooner. I wound up loading a different rom on the phone and away went the problem.
jank0023, I have no idea. I would flash the phone back to stock and return it for another if all else fails. In all my searching, here and elsewhere, there ahve been a handful of wifi problems I came across. It doesn't seem like that common of a problem afaik.

If its your router try another channel make sure its on a supported signal (a,b, g)... lastly ensure your router is excepting all devices. I know these are basic checklist items but sometimes these can get us. I had a laptop that would only work on channel 6 ;-).

Thanks guys for the suggestions...I don't think its related to my network setup as I have about 4 other devices able to obtain signals with no problems using DHCP.
Issues don't seem to be as severe on some of the most recent ROMs I've used but still not perfect.

[Q] WiFi can connect, but wont load pages and no Sync

I have problem with my Froyo Android and 2.6.25 kernel (but it was similar on .32).
I can turn ON WiFi and connect to my home network, but it has problems with loading pages (it wont load page at all most of the time, I only loaded google.cz once) and I cant even login into Google acc and Market.
My WiFi is working on notebook or other phone, but cant make it work on my Polaris and Android.
Anyone know how to fix this? Maybe some WiFi settings that Android or Cruise cant handle? Or some other fix or suggestion?
Thank you for all tips...

it wasn't kernel releated, try to change release (Fresh Froyo, Scoot's, Clemsys's)

I have tryed a few builds, but it seems to be allways the same. Wifi is connected but cant load any pages, when I restarted phone, it loads 1 page just after restart and then nothing again all the time (I cant even reload the same page again).
Its probably some settings or maybe hardare problem? I really dont know what to do or how could I test where is a problem. Probably only option is to flash WM 6.5 back and try to do something there... but still I dont know how to test if its maybe hardare problem.

So I have tryed WM 6.5 again and Wi-Fi works great there. I am glad its not hardware problem, but still it would be great to make it work on Android.
I cant access Market or sign-in account and Android is useless because of that, since USB connection also doesnt work :-/

So after I was sure WiFi is working in WM 6.5, I have tryed another Android again.
With clemsyn's RC1 build and 2.6.32 kernel I was able to at least log into Google account and access market. But WiFi is very slow only 1kB/s at max and drops a lot. I wasnt able to download Opera from market after 3hrs mainly because of disconnects. Sometimes it also crashes and show startup animation.
Now I know problem is in Android OS only, but I still dont know what to do to fix it or if it can be fixed at all (if not I have to flash WM back again :-/).

So noone has an idea?
I would be glad for any tips, because I tryed everything I found, but Internet is still dead :-/

Also with Radio 1.58.21.23 you still have that problem?

Yes, even with this radio ( 1.58.21.23) it remains exactly the same. I didnt re-flash system after latest radio update, because I dont have enough battery left for flash, so I hope it wont mind.
I will re-flash soon anyway because I am trying different setups all the time now
Only little difference seems to be between 2.6.32. and 2.6.25 kernels. While in .25 it never loads any page, in .32 I am able to load google homepage after a lot of trying (but nothing else).
I am allways downloading these throught Atools, because I dont know how to prepare different POLAIMG.NBH by myself, so I only tested two versions available there.
I dont know if it doesnt load page at all or if its sooo slow that loading timeouts. Is there any utlity where I could see if packets are being send or received? On the other hand it doesnt solve anything anyway.
But it can connect to WiFi site and with .32 it even transfer google page sometimes, so it somehow "works" and transfers some packets occasionally.
Sad thing is, that there arent much settings in Android system, so I cant play with that. I also tryed different settings on my WiFi router, but it didnt help at all.

if you use adb and ping google did you have time out?

I never used adb, but I cant find any console or link to shell in my ROM.
Should I install Android SDK and adb driver in Win or can I access it somehow in my phone?

I have downloaded "Better Terminal Emulator Pro" and "Terminal Emulator" and installed from SD card.
In command line I write
Code:
su
ping 74.125.87.104
after a few tries where I get 100% packet loss, I manage to get better results:
Code:
--- 74.125.87.104 ping statistics ---
72 packets transmitted, 9 packets received, 87% packet loss
round-trip min/avg/max = 158.338/328.306/1143.300 ms
similar on other website, also only after a few tries:
Code:
--- 77.75.72.3 ping statistics ---
51 packets transmitted, 3 packets received, 94% packet loss
round-trip min/avg/max = 1003.263/1090.418/1141.900 ms

Seems to be a problem with the connection with router...
How many devices are connected to it?
Do all devices work good?

Router itself isn't a problem. Only 1 or 2 devices are connected to it and they are all mine (notebook and mobile phone).
I thought it may be a problem, that Android port for Polaris cant handle my settings, so I tried different settings, but it was the same.
Router works well with LG Optimus One (Froyo) and even with my Polaris, only with WM 6.5.3 ROM and of course my notebook works well too.
I wonder where could be the problem as most of Polaris users have working WiFi. I dont thinkI have any different part of hardware in it and I changed all software related things many times ROM, radio, kernel.
PS: results above are with kernel 2.6.32 I believe with 2.6.25 I would have 100% packet loss all the time. As change of kernel is only thing so far that have some impact on this issue I think it could be with some setting in there. I dont know what things can be changed in there or how I could try different versions, so I only tried three versions (two that I can select in Atools) and one that came with Eclair ROM.

So I have found where can be a problem and it rly seems to be hardware releated.
As I said before, in WM 6.5 WiFi works well, but I found its only because there is option to set "Best Wi-Fi Performance (May consume more power)" in advanced settings of WiFi.
When I turn this option off, I get similar results like in Android. Wi-Fi is very slow, so it wont even load page.
I cant find similar option in Android settings, so I want to ask if there is similar option in Android hidden somewhere or maybe some shell command or file edit, how I can change it?

try to extract wifi_levels.sh from K_K vaniljeclair and change the level.

Hi,
I set it to "extreme" and it seems to be working!!!
Thank you VERY much for all your help.

WIFI problem after ICS upgrade

HI. Today I updated my non-rooted HTC Desire S to ICS 4.0.4 (3.0.16-gce03037 Kernel) from official site... Everything is working fine, but I have problem using the WIFI connection.
I can enable/disable WiFi, I have no problems with OS freezing when I switch on or off wireless, etc. I configured it properly (I did not restore any settings from my backup software) and manually, and in status bar I can see that network is connected. It seems that everything is working fine but:
1. I cannot access the Internet from the phone
2. My access point does not list my HTC as connected device at all
I am desperate because this is the only thing that is not working after upgrade, and I use WiFi a lot
Thank you all for helping regarding this.

I don't know if it is the same issue i was experiencing some time ago, but seems that older Wi-Fi router have some problems with ics roms and later versions (jelly bean). I have resolved by changing my router but you could try specificy a static ip address for your phone and see if it works.
Sent from my HTC Desire S using xda app-developers app

I already have a static IP defined. Also my WiFi is protected with AES. Is there any way to keep ICS on HTC and to degrade only driver for the WiFi?

No, I don't think so, but maybe the AES encryption could be the problem. Try swiching to WPA or WPA2 and see if it works.

Well, no. You could still try to root your phone, install a Jelly Bean based Rom and specify a static IP. JB is slightly better with WiFi than ICS so I think this is your last call.
Otherwise you can still use the pass-through internet option is "Stock option" of the Rom settings, but this means that the phone must be plugged in the PC.

Is there any 3rd party software which can manage WiFi chip? Something like option in MS Windows, where you can choose Windows to manage wireless or vendor application. Maybe it is not a firmware problem, maybe it is something with ICS subsystem/application which handles WiFi...

OK, now things are getting very weird!
First of all, I tried with "wifix" and bunch of other market "wifi fix apps", but with no success. After that I connected to my WiFi and try to ping my laptop which resides on the same AP and.... with SUCCESS! I looked at my AP statistics and I cannot still observe that my HTC is connected to the AP, but I could ping the laptop and default gateway (which is AP of course). I tried to do SSH to the HTC and that was successful too. It seems that my WIFI is working only locally, because when I try to ping public IP I get the destination unreachable error message. On the ifconfig's interface statistics I can see Rx and Tx counters increases on the wlan0 interface, but on the AP I still cannot see that my HTC is connected.
I looked up in to the routing table, and there was everything as should be. I am sure that there is no IP address conflict inside my network, I am sure that my HTC is authenticated and connected on the right wireless channel.
Guys, this issue is very weird, can somebody give some hint about it?
Please, see attachments there is much more info regarding this.

equally eelsec
Ok, here is the update in attachment, it seems that I have problem on the layer 3 of the OSI model. I think that I can summarize the following:
1. Radio is working
2. All MAC layer things are also fine
3. Encryption is ok
4. IP packets transportation between the HTC and router is not working.
I am not good with linux, and my phone is not rooted.What can I do to troubleshoot this part of the networking now?

Hello to all again.
Believe or not I still have the same problem. HTC support is USELESS... I tried with factory reset, and I still got a problem. I am loosing patience now... Can somebody tell me how to revert back to previous OS, please? Where to download, and how to install it?
