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?

[Q] Wifi performance after radio update?

I have been running the original sense ROM on my DHD downgraded from the 1.72 it came with to 1.32 to freeze bloatware and get rid of the annoying SMS notification bug. Was working great until I tried a new radio to see if I could improve my patchy Vodafone UK 3G sig.al at home. I tried the latest stable radio from Cingular and found 3G and GPS was good but wifi was suddenly terrible! Right next to router and only getting 'fair' signal. Thought I'd return to original 1.32 radio using the one in the radio thread but this has made no difference. Wifi signal is now poor upstairs with only my network visible whereas I was getting Excellent with multiple networks nearby showing. Is this a radio problem or settings? I never had best wifi performance ticked in settings. If it is a radio problem does anybody know how to return to the stock one that came with my DHD - UK unlocked used on Vodafone UK network. Any help appreciated greatfully!

Apparently these radios, unless WWE, are designed for a specific area. If you're not in the area you will notice some downgrading in WiFi functionality. Try a WWE radio and see how it goes.

shut down and restart your router and try again the wi-fi. that work for me the first time.
or you can boot into recovery and do a Factory re-set

Have tried most of the radios in the thread over in Desire HD development now with pretty similar results, even tried the UK specific test radio listed there. Currently on Radio_12.28e.60.140f_26.04.02.17_M2.
Have tried a reboot of router also, but that did little. I used to be able to see 4-5 nearby networks also but can only barely see one now.

Hi, would just like to report back to say I think I've fixed it. Is the wifi antenna connector on the battery cover like the network antenna is on the sim card cover?
Was at work and getting a really poor signal to the ADSL line here for external devices, whereas last week had nearly a full signal (2 rooms away). Just removed the sim and battery cover with the phone on so I could soft reset it in the process, cleaned the gold contacts and put back together and WiFi seems to be working great again.
Will report back later when I've had chance to test it at home but seems it was maybe a Darwin moment and I hadn't put the battery cover back on properly or the contacts were dirty?

That's good to know for future reference... cheers!!!

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.

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?

[Q] Wifi issues on CM7

Wondering if anyone else has this issue. My wifi is pretty weak on my EVO. i had strong connections before, and after, i rooted. But since i started running cm7 my wifi has become very weak. currently, my laptop has full bars, my friend has full bars on her intercept, but my EVO wifi shows only the dot in the wifi signal display is lit up.
Is this a known issue? and is there a fix? as i said, everything was fine when i was stock, unrooted and rooted.
running CM7.1.0, tiamat 4.0.8.
iv flashed several CM7 roms since rooting, all nightlies.
If this has been answered before i apologize. did a search for "wifi" and found no answers.

did u find a fix for this? i have the exact same problem

You may have low bars, as each device [phone] will register the connection strength, but as long as the data is there, nothing to complain about.

Try updating the radio. Somewhere on these forums there is a post with a combo zip that will update all of them all at the same time.

yeah, I had very poor wifi signal and 3g signal with cm7. Liked the look and feel of cm, but with poor wifi and signal strenght, along with gps not working and wifi tether unable to work, I went back to Fresh.

[Q] Signal Issue?

So I've had my VZW Galaxy Nexus since launch, and have absolutely loved it. It is by far the best phone I've ever had, and I've had zero problems with it... except for recently.
For the past few months I've had a problem where my signal bars get greyed out and I can't access anything, even when it shows I have full signal. This will happen on 3g, 4g, and wifi, and sometimes toggling airplane mode on and off will fix it, but most of the time I have to just wait for the connection to come back on it's own.
I've read about signal issues plaguing the Nexus, but I always thought it was just where it showed no signal at all. Am I experiencing the issue, or is it something else entirely? And is there anything I can do to try and fix it other than getting a refurbished phone? I have tried every radio combination out there, and have settled on the latest radios (l515.09 V.FF02 / l515.FG02) and the issue has persisted throughout.
TLR - Phone will often grey out bars and I can't connect to anything. Happens in 3g, 4g, and wifi. Is this the signal issue people have been talking about or something different?

Try getting a new Sim card. I've read on other Gnexus forums. That's good fix for the gray bar issues. other solution take out the Sim card and let it sit for a minute or 2 then pop it back in. Lastly a factory reset.

a signal drop is when your device's antenna looses conection to the nearest cell (tower, mobile transmission equipment) totally.
a data drop is what you're experiencing.
this is on stock rom, correct?
