HELP! Major network problem :(

Hi all,
I got my Desire from the British carrier "Three" last April when it came out. It was stocked with Android 2.1 but the phone was unbranded and not locked so making life much easier.
I rooted the phone weeks later and flashed a number of various roms and radios (usually newest ones recommended by rom developers) and just played around with them. No problems ever occured and everything went smooth.
However a while ago (about 4 weeks I would say) strange thing happened: when the carrier 3 does not gave 3G coverage it usually switches to other network's 2G roaming service. It is also possible to switch to 2G permanently by forcing it via phone settings. It stopped working in Central London for me while still worked elsewhere (very strange) so I had to rely only on 3G service. I thought it was a network issue at first but now I'm not sure.
Later (or at least so I noticed) the connectivity started fooling around: even when standstill (i.e. NOT in a train, bus etc.) and staying at home the network connectivity just disappears all of a sudden. Sometimes it comes back by itself and sometimes I just do it manually via netowking settings. This is much more common when on the move (i.e. on the train etc. even though it never used to happen before). Moreover, sometimes while manually searching for network it says "your sim would not allow to connect to this network" even though I try to connect to the correct one. Instead I switch "WCDMA only" and "WCDMA/GSM auto" options and connection comes back by itself. Then it disappears again after a while. Even more strangely, connection does not disappear if I am talking on the phone with someone but in other situations (such as browsing internet) it just disappears and I see no bars in network reception indicator and cannot connect to internet or make phone calls.
I know 3 has a reputation (deserved or not) of having "bad" network but I don't think this has anything to do with that. My Desire used to work fine before and never had such problems (except in specific spots which have bad coverage). Moreover, I have another old phone and it works fine without any problems with networking while the Desire messes around. I am sure it has either to do with firmware or, worse, hardware.
I have tried a number of roms, radios and settings and it's the same thing all over.
If nothing works is there a way I can still bring it to warranty service after flashing "unrooted" stock rom if there is one available? I'm so frustrated because I have no idea why this is happening.

Its because three have switched off 2g roaming I have the same problem. Search Google

Intermittent wifi connection problem

I have an annoying problem with connecting my Desire to my home wifi. When connecting the wifi symbol appears within a few seconds but sometimes it won't actually transfer any data for up to a minute. I'm currently using DevNull 1.0.4 with radio version 32.44.00.32u_5.09.05.30_2 but have had the same problem with some other custom ROMs.
My router is a Netgear, using WPA2 encryption and the SSID is not hidden. My laptop always connects within seconds, so I don't think that's where the problem is.
Installing Wifi Fixer does make it connect much faster, but a few times I've seen it fail the ping test and then reassociate before it connects successfully. Trying to Google this has not turned up anything terribly helpful, partly because I'm not sure how to phrase it.
Can anyone suggest what might be wrong and how to fix it? Wifi Fixer does seem to be doing the job but I don't think I should have to have a third party app to make my wifi work.

Update your radio to 5.14.05.08 or what ever the newest radio is. Also, go into your router and change the wireless channel settings.

Might have something to do with the default setting that HTC applies to the wifi connection I'm not to sure on the exact figures but from what I gather HTC set the minimum wifi connection quite high I know that I used to drop my wifi connection a fair bit on my desire HD until I used leedroids kernel and my connection is much more stable now

Thanks guys. Updating to the newest radio didn't help, so I tried 32.54.00.32u_5.14.05.17 and that does seem to have made a difference in that several times over the course of the evening I was able to connect with no problems. I'll also look at the wifi channel, is there a particularly good one to use or should I just use wifi analyser to look for a channel with no interference?
I doubt it's a default HTC setting as I'm using DevNull which ships with one of Thalamus' custom kernels, but I'm grateful for any suggestions.

I have a
HTC DESIRE A8181 (OEM unlocked)
Android: 2.2
radio: 32.44.00.32U_5.09.05.30_2
What's been done to my phone: last night & this morning (no sleep yet )
Rooted using Unrevoked
S-Off with Alpharev
Still like to flash an upgraded RADIO & RUU Rom
the problem i have:
NOTE: this was before last night changes (6 days ago it started)
basically i cant WIFI to my modem
my pc's are all ethernet cable but my modem leaked enough if i was next to it (at my main PC) i could wifi connect with my CP to update / go on to the android market etc etc.
Only if i was sitting close to my modem/router
i have this MODEM/ROUTER Iconnect 624W
SETUP: will give you an idea on settings.
http://support.onthenet.com.au/internet-setup/broadband-setup/opennetworks/iconnect-624/
THE FIX: THIS IS IN THE MODEM/ROUTER SETTINGS.
in "wireless setup"
i followed above instructions in the link - mine was basically setup SSID etc EXCEPT my CHANNEL B/G was set at 1 i changed to 4
i changed this setting after 6 attempts of connecting with no success i personally think this B/G setting on 1 was my problem. until i changed it to 4.
in "wireless security"
i followed above instructions as above again. SSID as above preset & just entered my "PSK STRING" (your password here)
saved etc as in the guide.
turned CP off & back on done a scan it picked up my modem entered the PSK STRING password
fixed & i can get internet in the back yard or any room now on my CP's
.

Well I've changed the channel on my router and the problem remains, it turned out that changing the radio hadn't sorted it. Still stuck with wifi fixer...

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.

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] portable wifi hotspot disables 3G ?

had the phone over a year now, never had an issue before.
As soon as you turn on the portable wifi hotspot, i loose the 3g/h symbol from the top of the screen and from that no data conectivity?
and as sopon as you turn the wifi hotspot off, it regains an internet conection
Any ideas, ive not installed any apps recently, as far as i can remember?

Do you get an internet connection when another device connects to your phone's wifi hotspot.
If you are able to connect, then it must be working, as it's the 3G signal that the phone uses to connect the wifi to the internet. It might remove the icon, but if you can connect then it's fine.

nope, can conect my ipad to the DHDs hotspot but no internet.
the same for when i turn the hotspot on, cant brouse anything on the phone as no data conection

still not sorted this, anyone else got a aide or something to sort this?

First post (longtime lurker)
I've got the same problem here although this has only started happening in the last couple of days. The phone's data connection is fine until you enable the wifi hotspot at which point the connection is dropped to the phone, connecting any devices to the phone is fine, they get an IP address and can ping the phone directly, but beyond the phone there's nothing.
Rebooting the phone does not help.
The only app I've installed recently is Google Shopper.
Out of curiosity Fil what ROM are you using? I'm on RCMix3d Runny 3.0 which is based on Android 2.3.5 and Sense 3.5. I'm looking at switching to an ICS build pretty soon.
It also looks like we're on the same network although I think that's just coincidence.

yep sounds exactly the same issue,
as for rom, still on t-mobiles original 2.50.110.5 Adroid 2.3.3
was thinking of flashing something custom to see if it solved the problem

I've just flashed IceColdSandwich today at work (it's been a slow day!) and you'll be pleased to know that wireless tethering is working again. I'm on the train home as I type this. It's possibly something in the 2.3 image? I can't really say since we both had different ROMs (mine was a Sensation port). It could just be a bad bit of code in the gingerbread OS that produces this bug on rare occasions.
It may have something to do with the fact that T-Mobile and Orange allow you to roam on eachother's networks. Do you have roaming enabled?
To be honest I'm just stabbing wildly at possible causes here and a flash fixed it anyway. I went ICS but I don't think you'd have to go that extreme but flashing a new ROM overwrites whatever it is that caused this in the first place.
I'm just hoping it's fixed in ICS and won't happen again!

cheers, enabled data roaming, and it now works!
Since the issue, my batterys turned to crap! guessing thats the cause constantly jumping networks, and also data speeds have been very poor lately, was ok when just t-mobile, but orange is poor!
Off to the t-mobile foeums to see if its just me, or others!

[Q] [GPE] Wi-Fi problems on 5.0.1 Lollipop

Anyone else have problems connecting to 5ghz any Wi-Fi networks after the Lollipop upgrade? I used the RUU zip to install Lollipop from scratch and I'm still having problems. First noticed the issue when I was setting up the account. Even then, the wifi would cut in and out when attempting to connect to my Wi-Fi. Not a router issue since other devices can access the network without a problem. Even then, after a router reboot it's still acting up. Rebooting the M8 doesn't help either.
Update: I was actually having problems with Wi-Fi in general as it turns out. Connecting to a normal 2.4ghz network was spotty and kept dropping. With 5ghz networks, it just didn't connect at all. I reverted back to the kitkat radio and everything is better now. Might try the Lollipop radio again too see if it may have been a one time issue or not.
