[Q] Signal strength issues with CM 7 - Droid Incredible Q&A, Help & Troubleshooting

I am running CM 7.0.2.1 with Chad's 4/19 kernel. My Dinc gets 2/4 bars signal strength on 3g and 3/4 on 1x at home while my wie's Env 2 shows 4/4 on both. So I decided to try a the new 2.15.10.05.06 radio and the 9.01 radio. Both updated with no problems. My dBm changed little, if any. (77-85%) I'm now running 2.15.10.05.06 and seems to be snappier. The signal strength bars are still less than my wife's though. Why am I not seeing the same amount of bars as my wife? (I don't know how to check her dBm) I did a *228. I get four bars at work but not at home like my wife. (Same problem at our lake house) Is there anything I can do to make sure I get the best possible signal strength? Should I try more radios?

How many bars your phone or her phone has doesn't really mean anything. It varies from phone to phone and signal strength isn't reported properly just by looking at the bars. Checking your dbm is the only way to really see where your signal is and some people seem to report better reception with different radios although it never seemed to make much of a difference to me. I'd check out www.dougpiston.com for radios, try em out, and look at your dbm, GPS lock speed/accuracy, and data speed to determine which works the best for what you need.

Is there any way to update the PRL on CM 7? I'm at 52297 and I've seen where the latest is 52299.

I think the custom menus might only be accessible from sense roms, so #228 might be the only thing you can do in cm7. You could restore a sense backup, update prl, then restore your cm7 backup? There might be another way to do it, I'm not sure cause I've never messed with my prl.

Cm nightly and signal?

So have the most recent nightly update cm, always shows low signal bars, but have most recent radio, any idea?

+1. I also saw my phone go to 1x for the first time while running nightly 104. Not sure if it's actually worse signal or if it's just a different interpretation of the signal strength. Suppose you could verify the actual db values from one to another.

(SOLVED) All users of CM6.XX and Ultimate Droid (AOSP) questions

I seem to have signal issues on both ROM's. I'll give you guys a little background information.
I've used Fresh and Myn ROM's and always get perfect 3G coverage in my house and around town. Everytime I flash an AOSP rom I can't seem to connect to anything but 1X (if I'm lucky). When I was using the 2 previously mentioned Sense ROM's I'd have no issues with data. For the record I don't do a restore of my system data or apps when I flash because I prefer to download everything again to prevent FC's and other issues.
I've done a nandroid restore and updated PRL and Profile in a Sense ROM (2X) and then restored my AOSP ROM (ultimate droid) and that doesn't fix signal issues. My girlfriend has an Evo and she gets perfect signal on 3G (4G as well but she has it off) so it's not network related.
I downloaded the latest radio and pri from the development thread and flashed them in recovery. That didn't do anything at all and may have been a waste of time.
I then did these steps:
Dialed *#*#463+#*#*
Clicked on Phone Info
Turned off Radio (waited 1 min)
Turned radio back on
Ran ping test (failed because of no data signal). I can make/receive calls but nothing data related.
Is anyone having this issue? This has prevented me from fully enjoying AOSP ROM's and I don't know what the issue is. I'm using the latest PRL but could it be that my radio is broken? I would ready appreciate any help.
*** Update ***
I'm typing this thread on my phone and it's displaying 3G in full bars and then jumps to 1X full bars. It's kind of random but never steady. If anyone can please help me with this I'd appreciate it.
By the way I have an Airrave. Could that be the cause of my problems?

Same. i have this issue. although i dont get 1X. but i do however get spiking signal.
from what ive learned, the bars arent ur reception but how good ur connection is to the....satelites? aslong as u have 3G showing ur phone/internet SHOULD be working. although i would rather like to see all full bars where i normally would
i'm in a pretty high 4g signal area, but i love ultimate droid. i too have loopy 3g using cm6 or ultimate droid, would gladly give up my 4g to use either of these roms, but the 3g performance is way slower than on a sense rom. it's not just the bars, 3g on aosp is almost unusable, on sense roms, it works nicely
I solved my issue. The root of the problem is the Airave and how it connects with AOSP ROM's.
When I flash a Sense based ROM I don't have an issue with 3G and signal. I'm in a perfect 3G area by the way.
As soon as I disconnected the Airave last night my 3G signal came back with a vengeance. It hasn't left and is steady. I plugged in the Airave again and I saw my signal disappear and never come back. I could make/receive calls but no data access. I have the latest version of the Airave. Could someone (DEV) of an AOSP ROM investigate this issue. I knew it wasn't my phone because it would only happen in AOSP ROM's.

[Q] Radio question.

Searching did not reveal the answer.
Before I rooted (2.2 and radio not known) I would have full strength anywhere in the house with WIFI. After rooting and installing CM7 my signal is weaker.
Installed 2.15.10.07.07 with no improvement or with 2.15.00.05.2 (current)
WiFi scanning in areas I used to receive service fails to obtain them.
3G seems somewhat weaker but that is only a guess. GPS is good.
Advice?
(or after rooting it is really now telling me the truth)
Wifi has nothing to do with the radio. Not sure what your issue is caused by though. Wifi bars may visualy change at different percents in different roms like battery mods do.

[Q] Poor signal on ICS roms, AOSP especially

Can anyone help with an issue I get using AOSP/ICS roms. On a GB rom I normally get 1-4 bars of signal in my house, 3G speed is fairly rubbish but it does work. Whenever I flash any version of CM9 or AOKP I get 0-2 bars of signal, and mostly no mobile data.
The phone can be sitting on a table and show 2 blue bars, often if I pick it up it will change to none and give me network errors. I can normally still send texts and make calls when it is like this, just no data and things like Play Store fail to connect.
Calk's ICS rom may be a little better, but not much (the signal meter on Calk's bounces between 1x and 3G along with low bars).
Switching back to a GB rom I get all my signal back and the slow but actually working 3G. I have tried several modems on both GB and ICS and they show no difference in behaviour (I have tried EL29, FD10, FD16)
Since I have wifi at home it's not a real issue for data, however it seems to kill the battery searching for a signal. The "Time without a signal" shows 20-30% most of the time on ICS, vs 0% on GB.
Any ideas on why ICS roms are giving me no signal?
Cheers,
Richard
I've been getting the same thing but the connection seems to be the same as when I was getting more bars on GB. This is especially true when I'm using Wi-Fi. I'll get one bar of signal strength but it is still fast and I'm nor having connection problems.

i'm having a similar problem, only difference is that mine on ICS was working fine untill i softbricked and restoring back to ICS using CFRoot.. now i (just like you) have 0-2 bars, and have tried dozens of modems and kernels to fix the problem..
eh, maybe i should go back to GB too - see if that fixes my problem
If you search around these forums you'll find something bout getting rid of proxies that the sprint server uses... some people have reported great success and increased service while others have had no noticeable difference, I myself haven't gotten around to trying it, bit I still plan to, sorry I'm mobile right now and can't find the post, I'll see bout linking it when I get home

I've done this on a couple phones and I've gotten good improvements each time. It will only affect your 3g speeds and not 4g, and it's not a guaranteed improvement.. there are many factors that can affect. Check your speeds before and after to see if it helps you or not! =)

Data dropping while I have full 4g signal (ATT)

Hello,
I am running AOKP JB v1 on ATT Gnex. I havent installed any other kernels or radios. My issue is that, while i have full coverage in an area i know i have data, while my signal bars show full with "H" above them, i cannot get data. Cannot send picture messages or go to google market or use browser. I think i need to flash a different baseband or radio but i have no idea which one i should be using or what is compatible. Can somebody please point me in the right direction. It is rather annoying to loose data constantly.
Well I really need help now. I flashed a radio but obviously it wasnt meant for JB. I have signal enough to text and make phone calls but no data at all now. It shows all grey bars with the H above it. Can anybody link to a working JB radio/baseband for GSM please?
I believe i should be use 9250XXLF1 but i cannot find a download for it
Edit: Found it here:

Try going back to stock completely. I do think its rather a network issue. Do you have the correct data plan for it?

I have been using the UGKL1 radio on ATT in Northern California - has worked well for me. Obviously, radios are very dependent on location but this radio was a big improvement for me.
They changed something with the network, allot of users reporting issues of data drops because its switching from umts to hspa and hspap constantly.

I see it constantly changing between the listed signals although the status bars show full w/ "H" above them. Tried multiple different roms. I switched from lumia 900 to this phone so my plan is good up to LTE. Shouldnt have an issue w/ that. Would flashing a different radio help?
