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?

CM 10.1 and 10.2 Deepsleep and 2G network problem

Hi all.
I tried 2 ROMs CM 10.1 23/11 and CM 10.2 26/11. I installed from 2.3 then install 4.1 with odin. Then make wipe and flash CM ROM
Both have same issue.
If I disable wifi and enable "use only 2g network" option in mobile network settings then my phone doesn't sleep. I have DeepSleep about 30-70%.
As soon I disable "use only 2g network" option in mobile network settings and my phone connects to 3G then I got DeepSleep >95%.
On stock 4.1 2G network works fine and deepsleep >95%
Is this a bug in CM 10.1 / CM 10.2? Or maybe I do something wrong?

I checked this bug on latest CM 10 build from jully 2013 and 2g mode works fine and deepsleep in 2g also fine

I had the same problem. I installed cm-10.1-20131123-UNOFFICIAL-codina on the official firmware I8160XXMG2_I8160OXEMG2 with wipe cache and factory reset. But I didn't have any internet connection even after twice reboot and long waiting. Now I've returned official firmware.

Sometimes when using profile manager to do this, I get an insane number of wakelocks referring to copsdaemon, which drains battery by a lot, still unsure what copsdaemon has to do with anything though.

I've got copsdaemon problem on my ace 2 too, even if i'm using maclaw's cm11 i think the process is the same.
Did someone find out what copsdaemon is and how to disable it?

By any chance, do you lose your internet/phone (2g/3g/gsm) connection completely when the copsdaemon problem strikes? I had a similar issue for a very long time, with different roms. The fix was to get the SIM card replaced as it seemed to have corrupted APN settings.
I mostly had the problem when I was driving arround, so the "access points" changed a lot. Whenever I was at home or at any fixed location I didn't have the problem.
Hope it helps.

Guys, unfortunately i have this same problem. My only option was just use the 3G signal (selecting on network settings). Its been passed 5 months and i still dont know how to fixed. I tried every ******* thing and the problem remains, at least choosing the 3g signal i can use my phone as a phone !!
obs: the problem started after updating to original MM.

I also have this issue, or similar.
Mine occurs when i connect to wifi whilst using 4g. If the 4g signal drops it wont automatically switch down to 3g. I have to do it manually , by changing to 2g/3g in network settings. auto/2g/3g/4g works fine whilst not connected to wifi though.
Mine seemed to start doing this when i first flashed MM or Fulmics.
I have tried flashing old radios, doing a complete unroot factory stock kds flash but nothing has fixed the issue.
Anyone any pointers or an explanation as to what could have possibly happened?
Cheers all

I had the same problem.
I flashed RPM and correct modem.
No signal drop anymore but no LTE.
Flashed modem again and RRom and it works perfect now!
I guess I should flashed the modem twice at the beginning.

Connectivity issues

Hello,
I have the global version of the mi9SE and experiencing very annoying issues when trying to access certain websites OVER MOBILE NETWORK (WIFI works) which returns errors as per attached screen shots, reporting certain sites (banking particulary) as can't be found or offline.
I temporarily managed to fix the issue by changing APN settings from IPV6 to IPV4 as per a suggestion on the forum of my French network carrier. Unfortunately with the update to android 10 and MIUI 11 erased these settings and now 4g or 3g for that matter simply fails to connect over IPV4 setting after update so I’m back to square one which is immensly irritating.
I can’t work out if this is a carrier issue or a software bug. I’ve tried the following :
- Changing Sim to another phone. No problems there.
- Changing browser. Both chrome and edge are the same as well as the native browser.
- Contacting bank who tell me issue not unheard of but have no solution.
- Contacting my carrier who claim not to have an answer.
I haven’t tried another sim in the handset.
Help would be much appreciated.

Hi
I also use French carrier, bouygues, using android 10 miuimix, just tried ing website and it works fine through 4g.
Have you tried a different ROM? You should have a menu to erase connectivity data in settings may be it could help

Hi thanks for your reply. Vey strange, I too am on Bouygues network and ING website doesn't work for me.
However I must point out that it is the secure part of the website that doesn't work so logging into the "espace client" part of the account, the home page DOES work. Same for you or not ?
I don't understand how it can only be me experiencing this issue which I've had for months now despite doing a factory reset, formatting etc. I'm using the stock global rom OTA from Xiaomi. I surely shoudln't have to flash another rom to get a working phone. I take it Miuimix is a ROM you're using on the Mi9SE ? Just how stable and secure is it ?
tks

MY WIFI hotspot won't work either. It connects to the network but refuses to connect to the internet. No such problem when placing the same sim into another phone and setting up the same hotspot. Could this be a problem with my device hardware I wonder ? I haven't done anything in particular...but these issues weren't there when I first bought the device.

For Hotspot I guess it's related to Android 10 update...
Just tried the secure part of the ing website and indeed it doesn't work for me neither on 4g. But Hotspot works fine.

Great thanks so much for trying at least I know it isn't just and so can conclude an issue with MIUI and the phone. Strange how adjusting VPN settings to IPV4 used to work but now doesn't. I fear the issue is embedded into the OS and I'll probably never find a solution . Wouldn't be so bothered if this was the only site but it's not. I first thought it was just a problem with the websites, then realized it wasn't when the same sites worked over WIFI.
As for the WIFI hotspot issue, still no solution to this problem. The same sim is fine in my Motorola and connects to the internet perfectly over 5ghz band. If I try 5ghz band on the SE, windows simply reports "unable to connect to the network" and over the 2.4ghz the device network will connect but reports "no internet".
It doesn't sound as If the two issues are related from what you say. Is it possible it's the windows firewall blocking the Xiaomi but not the motorola ?
