WiFi connection kills mobile network

I'm having an issue that happens about 50% of the time. When in a WiFi zone and connected to a router, quite often the mobile network will lose connection so I cannot make calls or send texts. None of the mobile bars are illuminated and there appears to be a little "x" above them. Leaving the WiFi zone disconnects from the router, but the mobile network still does not come back.
I have to reboot the phone before it picks up the mobile network again. It's really frustrating because without checking my phone, I never know whether it has mobile network connection or not (when i'm in a WiFi area such as work). I know the area i'm in has mobile connection, but WiFi just seems to kill it.
This is happening on the stock HTC ROM and the latest Oxygen ROM that I flashed to. Is this a known big or any tips/tricks?

Go to Settings > Wireless & Networks > press Menu, select Advanced, and check your Wi-Fi Sleep policy settings.

maybe you have an old radio? i would suggest that you try to flash another radio to see if it solves your problem. again, just a suggestion!!!

Hmmm, I did not know about that. I'm not sure it'll fix the issue, but the WiFi turning off an on did somewhat bug me, so cheers for showing me that setting anyway

Well, I don't know what my stock radio was, but when I flashed to Oxygen I tried the one the dev recommended. Perhaps i'll try another.
Would 3 Mobile be really annoyed if I took the phone in for help and it was flashed to a custom ROM?

You could also try a modified kernel and as suggested above, a different radio version as this can help with issues related to Wi-Fi reception, GPS signal strength, and battery life.
If you purchased the mobile from 3 Mobile, then they may suggest that your warranty is void as you have 'hacked' it. You can always flash back to stock ROM and then check if the same issue persists. If not, then go back to a custom ROM, try different radio versions and some may work better as it can depend on your network/area, and if still not resolved, try flashing a compatible modified Kernel from the Desire Android Development section of the forum.

I'm using Leedroid 2.3b with RIL optimised for 5.11.05.27, and I notice weak signal with WiFi, it is present, but WiFi bars change all the time, among other symptoms similar to those he has described. The other day I went out of range of WiFi network, but the phone hasn't switched to mobile network, but instead the WiFi icon remained and there of course was no connection. Would you define this as an ROM or radio issue? Is there any sense in changing the radio to other when the ROM developer stated this one is the best?
A few days ago I flashed the newest radio (I was using batt+ up to that moment) because I experienced echo during calls. Now the echo is gone, but this happens.

I think it could be ROM or Radio related... I was not aware that the associated RIL was to be flashed also although I know it is always recommened as it can provide an important part in handling the communication between the Radio and the Kernel.
Have you tried without the RIL and just the radio alone? Try that and see if it improves the situation.

I downloaded and flashed RIL for this radio. It shouldn't make any difference though since this RIL is supposed to be in the ROM already. :s
This radio is also downloaded OTA from our provider. I checked my sister's Desire, she has the same radio on her stock Desire (i.e. it was downloaded OTA).

Is there any good advice on what Radios work well and what they excel at? I see quite a lot posted, but no hard information on what works best
What I would love is one that actually picks up mobile signal. Where I live, we get very poor reception, however, usually 1 bar is possible. My Desire never picks up anything whereas my old N95 8gb used to get 1 bar as does my brothers phone.
It's good enough for texts at least. Any advice on radios then?

Wifi disconnecting

I have some problems with my wifi connection, i have to reconnect my wifi many times a day.. is there someone that knows what the problem can be? My device is rooted and s-off, i am using Ginger villain 0.9, but i have had this problem in all the roms I've been using. Btw. Wifi sleep is off

Some roms do mess up Wi-Fi and mobile internet and stuff. Try updating your radio to 5.14.05.17.

I do have the newest radio :/

Try this: Settings > Wireless & networks > Wi-Fi settings; then press Menu > Advanced > Wi-Fi sleep policy and set to "Never".

He said in the first post he already did that.
Flash both the newest radio and the corresponding ril. I did that yesterday and had no issues in the last 24hrs but can't say whether this solved my issue or not. If the newest doesn't work, try a little older and so on.

I'll give it a try. Thanks

Do you have a URL to download the files?

I have/had the same issue after using CyanogenMod 7.
I think it is because the custom rom enable 802.11n. After I disabled the 802.11n on my router and only using 802.11g, there has been no problem after that.

I have the problem on all a/b/g/n etc. :-/

Same problems here with oxygen & redux ginger rom's. No wifi problems with others, non-gingerbread roms. Could it be wifi router issues because only small number of us having this?

I have been going through about a dozen roms and my WiFi does not work.
Solution is in the WiFi router setting. I changed the TX rate to 1-2 mps. and everything works.
Sent from my HTC Desire using XDA App

hmm
I have tried on 10 different routers, same problem every time. But I remember that I installed 802.11n mod for a long time ago .. perhaps it's the problem then? Is it possible to reinstall the default wifi module? or is that a part of the ROM?

Up this... Tested ginger rom again (redux v1.0.0-RC6), and updated my router (Netgear WNDR3700) firmware to latest and greatest, and no wifi disconnections anymore!
I just don't know if it was rom or router fault, but now it's gone.

wifi problem 2.3.3

Regards
I have a problem with wifi after I put update on 2.3.3
whether it can solve this problem with wifi.
I always shoot and it turns the wifi network.
be a good wifi network signal then disappears

Same problem here

This is a very serious problem. Get ur act together HTC, this is just unacceptable!

Are you rooted? HTC raised the signal strength at which the connection would be dropped, there is a fix if you are rooted, otheewise you are stucm and will have to wait for HTC to correct this.

Have you tried another radio? of course be careful if you do change it

same issue, though htc say that its a "new feature" to provide a seamless mobile broadband experience by automatically chosing the strongest signal. whatever you say htc
i just disable mobile data at home, so it cant jump back to 3g and stays on wifi. the annoying thing with this is that i forget to enable mobile data when leaving the house.
i hope they sort it out, and that this new feature isn't rolled out across their other products

I am having the same problem. At work, my wifi connection is weak, but was always functional. Now, I cannot connect to my work wifi. On top of that, my battery drains twice as fast on my phone, and I'm thinking that it's due to the phone always scanning and trying to connect to the wifi signal. If it's true that HTC changed the level at which the wifi signal is dropped, this was a terrible decision.

I think this may answer/point to the problem I'm having since installing the Gingerbread RUU. I use the quick settings app from the market and pre-gingerbread it used to switch between wi-fi/mobile pretty seemlessly, turning off the unused option. Now if there's no wi-fi connection that option seems to stay on (probably searching) while it's connected to mobile data. As above, my battery is draining like a sieve.

Same problem for me with Original Rom.
so i tried the Revoloution HD 5.1.4 and same problem again!

Hi guys until HTC release an OTA fix (that's if they do) the only way to resolve this is to root and then try some different ROM and radio combinations until you find one that works for you.
I find the ROM and radio from my signature work really well on WiFi but if you are going to do this make sure and root, gain S-OFF and ENG S-OFF. Also make sure you have the correct RIL for the ROM and radio that you are using
There are lots of threads on the dev section that guide you through this.

Wifi connecting
I have a similar problem with wifi connection. Only it doesn't disconnect during a connection but when establishing a wifi connection it takes much longer than it used to on Froyo. Anyone else noticed this?

i have problem too with wifi

I really hope htc has stopped the updates and resumes with a new build with the wifi problem fixed

The issue is with the Gingerbread Sense ROMs.

我更新2.3.3 是 CoreDroid_Desire_HD_GB_2.3.3_V6.2_Release_Version! wifi 目前一切正常!不知道你是用哪一版2.3.3?

I update 2.3.3 is CoreDroid_Desire_HD_GB_2.3.3_V6.2_Release_Version! wifi now everything is normal! do not know which version you are using 2.3.3?

I' using Revolution HD 5.1.4 with latest Radio and RIL

WiFi problems with routers
Hi there,
Same problem here. Both my WiFi router and phone say signal and reception quality are perfect and connection it stable, but data won't flow.
I'm having this problem with my Speedtouch (WEP key) router at home, whereas a Sitecom router at the office works fine (WPA etc. key).
Tried some work arounds, without success
Regards
***EDIT***
I can add that it has nothing to do with the reported threshold of -88dB signal strength. As I checked that with the *#*#4636#*#* option and both higher and lower values of the WiFi reception don't make any difference. The problem persists.
***EDIT v2***
The suggestion posted elsewhere to change from WEP to WPA didn't work out either
***EDIT v3***
Reverted back to ARHD 3.7 and WiFi is running fine again .
Hope some fix will be found soon!
Regards,

Is there any solution. I am trying to downgrade the radio but no chance.

If I use LeeDroid or Revolution will this same problem be there?

wifi problem with gingersense roms

hi guys, since I started trying gingersense roms, I alway had the same problem, wifi drops when signal is low. I never had this problem with froyo roms. There is a fix for this problem? This is very annoying for me, because in my home wifi signal is always low, but I havn't problem with other devices.
Thanks.

Some news, if I switch off 3g data connection, WiFi hasn't any problem, but if I turn it on, WiFi connection drops and I must go to WiFi settings and it riactivate itself.

Are you sure this was working on Froyo?
From my experience I can say this was the same with 2.2 (Desire stock ROM).
Not really sure this is a bug btw. If I tell my device it can use 3G networks I think I should expect it to switch to 3G as soon as Wi-Fi signal becomes unreliable...

Yes this is the right behavior, but when WiFi drops, if I go in WiFi settings, my device automatically reestablish the wifi connection. This seems a bug!

Also got the same problem here.

I tried to change radio to 5.17.05.23 and i've changed wifi advanced settings to improve wifi signal, but the problem is the same. When wifi signal is poor, it drops and I must go in wifi settings to reestablish connection.

Try changing channels on the WiFi router.

I don't think I can do that with my university internet... and it shouldnt be the channels, the phone seems to be the problem, more specifically the ROM

I'm having this problem also. Until Insertcoin 2.0.1 it was ok. Since the first GB releases Wifi drops much earlier than before if the signal gets worser .. atm I'm using Insertcoin GB 1.0.3

Same problem with reflexs 2.0.5

Hrrrm i just flashed Leedroid 3.06 just to test it here... i have no issues, i am actually able to connect to an open network down the street...
I also flashed the latest radio avail too

Leedroid 3 is based on Bravo Gingerbread HTC Asia WWE 3.06.707.0
I' talking about Ace S 2.36.405.8 WWE base, Gingerbread 2.3.3 android (GRI40) based ROMs, like insertcoin or reflex s.

Yes there are many places, that I know, my Wifi is working flawlessly with Froyo ROMs (eg. my bed, in the back of my garden or the wc at work ), and where is no connection, or where I have to connect manually with GB ROMs.
I was wondering,ifI this is a issue with my phone only ... but it seems not

Is there a fix for this available?

I'm having this problem also. I'm using InsertCoin GB 1.0.3

With Insertcoin 1.0.5 and Blade wifi fix (downloaded from market) the the situation has improved, but the problem has not yet been resolved.

I got the same problem with WiFi dropping when 3g is on. Also with leedroid 2.3 my 3g was off but connected by itself when there was no WiFi around. With Insertcoin its not working.

Same issue here with Oxygen 2.1.3 and Radio 32.56.00.32U_5.17.05.08.
Cant confirm if its 3G related or not. WiFi connection was stable for 10min with 2g only. Another 10min with 3g enabled and i've got a disconnect again.

I've the same problem since upgarding to GB ROM.
I found a fix for Desire S - see link http://forum.xda-developers.com/showthread.php?t=1051674
Any chance to have the same for Desire?
Thank you

GPS issue when mobile data is enabled

HTC ONE M8
Custom ROM android 9 lineage OS
I have recently noticed problems with the GPS on my device. Google Maps and Waze many times the GPS signal drops and can not determine the location.
In my test I could find that the GPS problem happens when the Mobile Data are active. Just disabling mobile data and GPS back to work with good accuracy and even on rainy days.
I researched on the Internet and can not find a solution to the problem. Already restored the network connections and even restored the factory settings.
Please help me... What is the problem ?
