I have not had any issues with going from WiFi to 3g but the issue that I have been having with ever custom ROM I have tried is that the network signal strength is very weak , it seems like the cards signal reach has been lowered for both WiFi and 2g/3g ,what can be done about this is a there a way to over clock The cards to get more power out of them?
Sry if i posted this in the wrong place

Hi,
I have some data connection problems since the first day i bought my DHD.
The phone reception signal bar are always changing even when i am not moving at all.
It can generally move from H to 3G a few times, then go to E and then G, in a few seconds.
it always moves, my internet connection is very slow.
It's as if the radio was always trying to renegociate the method of communication (GPRS, 3G, etc) with the operator's antenna
When i am in a phone call, i got disconnected sometimes or the sound stop during a few seconds (the time the radio switch from 3G/H to E/G i guess)
When i disable WCDMA from the settings i get a quite stable sound during my phones calls (maybe because the phone no more tries to negociate). But for Internet... it's just slow.
I tried a few ROMs, and their respectives radio rom (the one with the IRL branded in the ROM) i sometimes thought it was better but always it's still too unuseable.
I tried my SIM card in an iphone 3GS and i am usually in Edge (sometimes 3G) but when its 3G i can surf quickly during hours (if i don't move). This is not the case with the DHD.
btw i am on the french carrier SFR
If any of u had any clues i would really appreciate your help.
Thanks you
what rom are you using and what radio and ril................... now what radio are you on now
OP already stated he tried numerous ROMS and their cooresponding radios. Sounds like the signal is that degraded that any radio/ril combination will not help.
Thanks for your replies.
As said i tried many ones with their respective recommanded radio.
I am actually trying Radio_12.62.60.27_26.13.04.19_M with Android Revolution HD 4G_6.1.1 with no sense script.
Are there tests i could do to identify if its a hardware problem (like standing in front of an antenna and running some special tool maybe)
Btw, i also tried :
-RCMix3D_Runny_v1.3 but does work with internet pass through (wich is really important since i can't use internet from my phone carrier...)
-niarkMIUI-3.9.1
-LeeDrOiD_HD_V4.0.0-SE-3.0-BETA with Radio_12.54.60.25_26.09.04.11_M2
-cm_ace_full-203 with my stock radio ROM
-virtuous_unity-v2.37.0 with i don't remember wich one...
P.S : i would be Glad to test any ROM / Radio combinaison you would suggest me.
Thanks by advance for your attention
if you tried all those roms and diffident radios seems like its more like a hardware or provider issue does it happen off different towers or maybe you can go to one of the stores and try the phone at the store with yours at the same time?
Thank for the advice indeed i need to try this.
Do you know what i need to revert back for the tech not to tell the waranty is over since i have flashed my phone ?
Does i need to reflash the recovery etc? is there some tutorial in this subject because if i go to the store with my custom rom i guess i won't get too much help :/
Don't even take out your phone, your going to say your just looking, don't show anyone your phone, they won't even know what to look for, just test your phone to the one at the store, make sure apn's match. But if you return your phone you'll need to ruu back to stock. You can search easy s-on

What happens if you manually select 3G only, or 2G only from the settings menu? Does it just lose signal, or stays strong?
Hi
If i select 3G only
I first get no reception (as if when switching from 2G to 3G the radio had to restart)
Then the 3G signal appear strong, decrease slowly in less than 30 seconds, and after all, it seems quite stable.
The bandwidth is good i am downloading fastly
(i am commenting in real time)
Still no deconnection.
I will try it during the whole day and tell how it is behaving.
umm during a few seconds, there were no indicator (no 3G or H), just 3 bars.
It then restarted in H with 1 bar (i am not moving at all)
What will happen if i have no 3G in my area ? I won't be able to receve a phone call ?
Thanks

If you force it to 3G only, and you move out of 3G area, then you should either get a no signal indicator, or if you have roaming enabled, you would get the roaming indicator. I'm curious now because as you said you aren't moving, and it's still changing. That shouldn't happen. Hmmm
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
Hi there,
I am facing an issue related to 2g signal on Su640 stock rom v30d.
2g signal is almost 0, and sometimes the phone shows emergency call only. I must switch network mode to 3g in order to make calls.
If I flash CM10.1 rom, 2g signal is very strong.
Do you have any idea how to fix this?
Thanks in advanced!
I have purchase F240l from online store but i have serious signal reception issues with this mobile.
1- In outdoor Network reception is around 5-10 dbm less than other mobiles. But the real problem comes when i am in low signal areas. This phone will disconnect all of sudden after -95dbm. while other mobiles are still locked to network.
2- The wifi reception is poor as compared to other phones.
3- The GPS never locks. in GPS test it shows 28 satellites in view as soon as GPS test is started but actually all signals remain at zero and in view satellites also remain to zero.
I want to know if this problem is related to hardware or software.
Also if you guys can suggest some solution to this problem from your experience it will be very helpful.
Note: I have reflashed stock jellybean and kitkat roms by lg flash tool but there is no change in situation.
Replace the build.prop

You should try this Method.
This might solve your problem. You should backup your original build.prop in case things goes wrong, also make a Nandroid backup.
Btw it didn't work for me actually 'cause I had other radio issues with my phone.
All the credit goes to Akhtar Ali Jatt... Thanks him if it works.
I was already on custom build.prop to get rid of the Korean rom problems.
Yesterday i also installed Sphinx 3.0 which is supposed to have better signal strength.
But all of this did not work.
I want to know if other f240l users have same problem because it is not optimized for international use.
Or this problem is specific for my phone.
For hardware issue, i improved the antenna connections with pcb but still no change.

Many users have the same problem so there's nothing you can do to get better wifi signal.
Ps: my F240L is also has very weak wifi signal.
Any news about this issue? I have F240L with weak WIFI and GSM signal.

Hello community,
1. I have a low wifi signal - about 10-12 dbm less then my old lg g3 or lg g5 or galaxy j7 pro - seams it is just an integrated wifi antenna issue and there is no way to fix it
2. When scanning wifi networks I have a very not stable results: even when the signal is excellent about 55-60dbm the ssid is appear and goes all the time occasionally - seams it is a wifi driver bug
Especially I see it when using WIFI analyzer.
Couple of days before I opened thread with Sony support and don't have answer.
I must have the WI-FI card working well !
Someone have the same issues?
Someone have any ideas about fixing the low wifi signal ?
Thanks,
p.s the wifi connection is stable with day by day standard usage.

hi
I CANT EVEN USE WIFI
like u said,i found my signals are very weak at the first.
i think its just a bug and didnt care about it
however 1 week later my phone suddenly cannot connect to any wifi.all the wifi spots are shown as almost no signal and it will repeat"connecting,saved"'
and i found this is a serious problem,used Xperia companion to fix that
But it didnt work and i couldnt turn on the wifi option now.
it will reboot when im trying to turn on the wifi option.
i think its likely to be a hardware issue,but my LTE worked very well without problem.
im very Confusing now
