I've read that lollipop ROMs have problems with BT and sometimes WIFI. Just search for fix in rom thread or change to different with implemented fixes. I believe Ressurection is the most supported

WLAN Signal extemly low (1 bar @ hotspot )

Hello together!
I have a problem with my Desire
I'm using CM7 since months without troubles.
But from one night to the other my wlan signal is extremly low, i have one bar of signal strength directly at the hotspot (no problems with other mobile phones or notebooks etc)
After that i tried many things:
newest radio, newest CM7, a new middle case ... without success.
The GPS signal is good ...
I think the Bluetooth signal is also not so good, but i don't have a reference here.
So i hope anybody can help me here!
Thanks pmneo
but does your wifi work ok , i mean are u able to surf on ur phone with wifi ??
or do u have to sit near the hotspot for that ?
i can surf about 3-5 meters around the hotspot.
Before i got that problem i was able to surf everywhere in the house ...
Do you also have the problem with other hotspots?
If not it's a hotspot issue (change wifi channel or something), if so I would advice to test it with a standard rom to be sure.
If it's still bad with the standard rom after that it's probably the hardware of your phone.
Try with another hotspot. If problem remains, do a backup and hard reset, or you can even try a new rom.
I tried the hotspot @ work -> same problem
I tried some other roms -> same problem
I think the antenna is the problem ... does anybody nows where the antenna is located?
Thanks pmneo

What rom and what kernel are you using? Did you installed their fixxes?
I tried CM9, baseband 64, SaOSsinX MIUI v4 ICS baseband 56 and kernel as provided. Both roms dosent have wifi fixes. But if i use GB MIUI my wifi works well.

[Q] Wifi in CM9

Does WiFi works in CM9 ????
I can't use it with my phone
It turns on but don't find any wifi conections
Sorry for my bad english
wifi works in this rom.
The only problem i have is that the wifi will disconnect when many data is send through wifi. But that can be a problem on my end, because before the last update it all worked fine.

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.

Problem is connecting with Airtle 3G.

Guys help my my Canvas A1 is not connecting on airtel 3G since 2 days I had tried many methods bt, nothing seems to work.My area has airtel 3G network bt my A1 is not connecting when I switch to3G it says No service and after 1-2mins it automatically switches to 2G edge on 3G mode.
