[Q] WiFi hotspot was working well but has now dissappeared - General Questions and Answers

Phone: HTC Hero GSM
OS: Cyanogenmod 7.2.0
Was using the WiFi tethering to share the 3G connection on the phone to my laptop when travelling. This was functioning just fine until a few months ago.
Now, the function has dissapeared completely. When I write completely I mean just that. The settings aren't even seen in the menus anymore.
Does someone have any idea what might be the reason for this?
I've read somewhere that some apps handling communications might destroy native functions, but the only such app I've installed is Viber and the function remains gone even though Viber is now uninstalled.

[Q] Internet problem on Android 2.2 on HTC HD2 T-Mobile

THank you !!
Hi kincawine3
I have the same problem. I live in the Netherlands with Tmobile as my carrier, full data plan etcetera.
I installed android 2.2 my wifi works, my internet doesnt. It says 'connected', it even shows the right icons in the taskbar, but no internet.
I tried erasing my apn settings and resetting them and I tried factory settings but to no avail. I ringed Tmobile about it and (as was to be expected) they couldnt help since they suggested the above.
Help would be immensely appreciated.

First of all, make sure you're not set to a static IP (which i assume you're not).
You might also want to check a different kernel. I'm not familiar with the kernel used in your build so i couldn't tell you what to expect - but there are 2 kernels running for the HD2 (hastarin's and mdj's). you can try to use them and see if it helps. the older builds had problems with ppp which are now (more or less) fixed.
read the instructions on how to replace the kernel and let me know if you run into any problems.
Thanks Nir
Hi,
While i do not share the problem of no internet access, the connection drops off regularly. Why, but more practival how do I fix it?
I can often see the signal switching from 2G to 3G to HSDPA, perhaps this has someting to do with the connection going dead. Is there a way to keep the signal fixed on 3G? Like there is an option to only maintain 2G connections.
When i go to Settings and disable + enable internet access it works fine. Sometimes the connection goes dead every five minutes, sometimes rarely.
Facts: HTC HD2 WinMobile 6.5, Android 2.3 via SD card method.
Unlimited data plan.

[Q] HTC Aria 2.2 - Internet Connection Problems if WiFi and 3G are On

I'm having a problem that I can't seem to find a solution to anywhere.
I have an HTC Aria running 2.2 (I didn't do the OTA update. I flashed it myself) which is giving me connection problems if both WiFi and 3G are active at the same time. It only started happening after I updated from 2.1 to 2.2.
WiFi off, 3G on: I can use the web browser and all my apps that require internet access without a problem
WiFi on (and connected), 3G off (Airplane Mode) Same thing. No problems.
WiFi on (and Connected), 3G on: All of a sudden, I can only access the internet from certain apps. The Facebook app works fine as does the HTC Weather widget and shopkick. However, the web browser just hangs without loading pages, xkcdViewer throws me an error saying it can't connect to the server and the TD Bank app doesn't load.
I've been playing around with different settings and nothing seems to work. I found a temporary solution by going to Wireless & networks > Mobile networks > Access Point Names and resetting those to default, though that only lasted for about 10 minutes before the problem started again.
Also, when I was running on 2.1 the Market would always force the use of my 3G connection even if I was connected to a WiFi network. The only way to bypass this would be to put the phone into Airplane Mode and then turn WiFi back on. Now, on 2.2, the Market forces 3G, but only for a couple of seconds then switches back to WiFi, but I've noticed that sometimes the 3G connection remains active even after closing the Market.
Any suggestions? Was it just a bad flash of the ROM?
I seem to have fixed it.
I turned off my phone, removed the SIM card and booted it up. I connected to my WiFi and used the phone normally for a couple minutes. Then I turned it off again, replaced the SIM card and rebooted.
It seems to be working fine now. Hopefully it stays that way.

[Q] LG Optimus Wifi connection Internet problem

Hi everyone,
I got an LG Optimus 7 yesterday. Everything seems to be ok except
Wifi connects but I cant access the net on any program, 3g works fine.
Has any one had any similar issues??
Or has any ideas???
thanks alot
Same problem here...
Hi,
I developer unlocked my Optimus 7Q (C900 Quantum) and since then have had no problems with WiFi signal in the status bar, and I can browse using IE and connect to marketplace and other stock apps. When trying to use the network on 3rd party apps (Facebook, engadget etc) it say there is a connectivity error.
I have looked on other posts on XDA and found a fix for samsung devices, can't find anything on MFG.
The only WiFi tweak I have done is enable the tethering option in settings using WinTT - I hardly ever use my cell data connection though, so it was a bit of a stupid addition. There is no way using WinTT to remove the registry edit, can anyone post a way of removing this setting option and/or reverting any tethering changes? If Hard Reset is the only option, let me know.

[Q] Enabling Wi-Fi Crashes HD7

My HD7 worked without issue from the beginning of the year til around a month ago.
All of a sudden, my WiFi became extremely unreliable, sometimes taking an overly long time to recognise or connect to an obvious access point, sometimes finding none at all.
After I do manage to connect wirelessly, I see no speed increase in data transfer to suggest that the phone is even using the wireless link. Web pages sometimes load slower than over 3G. I had read that HD7s have trouble using certain WiFi protocols and adjusted accordingly, but the workaround was to no avail.
Additionally, once WiFi has been selected, I cannot switch it off. I am 'locked out' of the WiFi settings page. When I tap it in the menu it responds as if I've nudged it but it cannot load. The only solution is to remove the battery. On occasion, this stuck WiFi has also caused the capacitive buttons, camera and power switch to become inactive. Curiously, touch screen function seems unaffected.
I thought maybe this issue was tied to corrupt settings with my hub, but changing SSID / WEP key etc etc on my router hasn't fixed the problem, and connection to other open WiFi signals jam the phone just as badly.
I upgraded to Mango in the hope that a fresh OS update may 'rejig' my wireless settings into working, but again, no joy.
Anyone experienced anything similar? My final options seem to be factory reset the handset to see if that solves the issue, or return the handset to O2. (Both involve losing all my data, game saves, application data AND the recently delisted SW: Battle for Hoth permanently.)
Anyone got any other thoughts?
*EDIT* After a bit more research, I found that even when the phone has connected to a WiFi source, by turning Operator Data Service off, you can see that the WiFi service is in fact not doing anything.
I braved a factory reset, managed to whack WiFi on no problem, browser ran at appropriate speed, then everything crashed as per usual, I couldn't connect to the marketplace and had to pull the battery in order to use any of the capacitive buttons. I guess it was a hardware issue individual to my phone after all.
Guess I'll give O2 a ring sometime soon to sort a replacement. Not looking forward to losing all my game progress though it has to be said.
bro i m having the same exact problem havent find any solution yet i even tried to copy and replace the wifi files from another clean htc hd7 but useless when i upgraded to 7740 the wifi worked perfectly for 1 night only then at the morning it stopped working, everything else works great. my theory says that its not a hardware problem cz i used internet sharing which uses the wifi adapter (if i m right) so its a software I GUESS

I had the same problem as well, couldn't connect, got to the point where even the power button stopped responding. Hard resets would only help for a short time and enabling WIFI would never connect right and eventually get me back to the same problem. I then got a replacement device, but it's not much better, I still can't connect to any WIFI, but at least it's not freezing up on me. My solution thus far has been just to avoid turning on WIFI if at all possible, but it's far from a perfect workaround. I'm guessing it's the HTC WIFI driver that's got issues.
i got similar problem.. send phone to service problem was "circut board"
replaced working fine...
when i was using wifi my phone was freezing some menus stop working and i have to remove battery

[Q] 3G/Wifi don't work together

Hi guys,
My wifi/3G problem started with the 8107 update (Omnia7, not KK2), and i read about others have the same issue too.
The wifi connects to my home/work wlan, and strangely sometimes (but that's rare) working, and get pages to load on, but after a while it still shows the connection, but can't load any page in IE.
After i have done a hard reset, and reverted back to 7740, i don't got any problem to connect to my home wifi. I decided to update one more time to 8107. (If something will go wrong then I have a backup of my Omnia7 with WP7 Easy Backup).
@8107 the wifi keeps giving errors if 3G data connection and wifi is also turned on!
If i switch off and back the data connection switch (!!), then the wlan works again for a while. If i switch data totally off then works flawlessly.
I think the problem is only appearing if the 3G and Wifi is also switched on (maybe the OS doesn't handle properly the network settings in this situation)
Any workaround for that?
Maybe a homebrew, that can switch off data connection temporarily, if the phone is connected to a wifi network, and after disconnecting it will switching back. But I think if it can be done, than just on fully-unlocked roms (i have Omnia7, and unfortunately DFT SammyRainbow is not ready yet)
Or are there any registry entry that I can use to set this?
So any suggestions what to do?
I second that. Exactly the same behavior on HTC 7 Mozart since 8107 :-(
Happening to me too, Optus branded Omnia 7, 8107. WiFi works fine as soon as I turn data off, but its getting really annoying!
Have you guys interop unlocked? Im wondering if its related to that.
