CM7 nightlies signal issue...

Just was wondering if anyone else was experiencing poor signal with wifi and cell with these gingerbread roms and if there was anything that can help? I have the latest nightly installed and wifi is always at 1 bar most of the time and cell signal is 2 bars or less in a strong sprint area...thanks in advance!

I'm sure this will be fixed once a stable release is out. Keep in mind they ARE nightlies. Otherwise try wiping and reflashing

I'm having the same issue - on build 24 on mytouch 4g (sorry for posting in wrong forum, but didn't see any mention in the mt4g forum.

1. my service signal literally never goes over 2 bars
2. Gps keeps getting lost, it feels like it gets it for a sec updates location then freezes(Google nav)
Haven't noticed any problems with wifi

Cyanogen gives your the REAL signal strength. Compare you db in the system info to that on a sense rom. The numbers will be the same.

I installed n24 and have a full 4 bars of 3g signal! Last night I had full bars for wifi as well.

Jaimster that is what I am experiencing as well with signal...doesn't like to go over 2 bars...and wifi is weak...there is a gps fix which involves flashing a sense rom and dialing the ## code for clearing the gps...then reflashing back to the cm 7 rom...it worked for me and a lot of others...I'll try the latest nightly and see what happens with signal

I normally have around 2 bars standard, though had max bars in better area coverage. They are nightlies and should be fixed once it becomes stable.

I get horrible reception on the nightlies, probably because it's a nightly and not a stable release so I'm not complaining. But, my wifi is only 1 bar if I take more then 5 steps from the router, and only gets 3 if I'm within reach of it. Cell and 3g are just as bad as I have not seen above 2 bars either, no matter where I am. Switched back to mikfroyo tonight because of it. I'm sure it will be fixed in a stable and more so in a RC though because Cyanogen and his team are pretty badass lol.

Regarding wifi at least, when the phones first came out the wifi reception was crap, it wasn't until the 3rd or 4th update did the signal strength more than double. Seems like Cyanogen is still working off the wifi drivers from the very first evo RUU still, since many people say wifi is worse on CM for 6.x and 7, compared to the latest sense.

I have the same problem too. Extremely weak wifi and cell reception. Have the exact same problem in other CM-based ROMs such as the CM7-EX.l33t. I have to be within 10 feet of my router to hold on to a connection. With other sense-based ROMs and the stock ROM, I would stay connected all over the house and my cell strength indicator was a solid 4 bars.
Using Wifi Analyzer, I get -35db with the stock sense ROM and -75db with the cm7 nightly (currently on 27).
Hope they get this fixed soon.

The following method has worked for many. This should fix your GPS:

Thank you GALT!
I understand when most folks have said GPS works they are referring to lock. I am talking about tracking! I drove around the neighborhood and google maps tracked me perfectly (with a little label saying 'accurate to within 20 meters').
Admittedly, it was a 5 minute drive. I have a 3 hour one later today and I will test it again. I will use the navigation and report back.
You will need:
1. A 'sense' ROM currently running on your phone (I had Fresh 3.5.1)
2. MSL reader installed (get it from the market)
2. Have CM7 (build 17 worked for me) and the latest gapps (I used the ones from 2011-01-15) downloaded to your SD card
Steps:
1. Open MSL reader and get your MSL (jot it down)
2. Launch phone dialer and dial ##GPSCLRX#
3. It will ask you for your MSL, enter it.
4. Upon hitting OK, your phone will just say reboot in 10 secs, let it reboot.
Phew!
5. After it has rebooted, boot to recovery (i used clockworkmod 2.6.0.1)
6. Nandroid backup (if you are so inclined)
7. Wipe cache, Dalvik and then wipe data/factory reset
4. Flash CM7 b17 from your sd-card
9. Flash gapps
10. Reboot and walk through set-up. Your gapps will be downloaded from the market. Wait for all the downloads to complete.
11. Use GPS as normal and enjoy the GPS goodness
I am not a developer but this worked for me and I hope it works for you too.

*sigh*
Sense shows which is higher: 1X or 3G, regardless of what you're using. Sense also has 6 bars and stacks things so that what should be two bars shows up as four and so on.
This is why I hate bars, and want the -dB display from CM6 in CM7.

Can anyone explain the erratic signal?

My phone acts very weird and I don't know if it's normal or not. My phone's signal jumps between full bars and then 1 or no bars when I surf the web or send a picture message. It's downright annoying. Sure, it usually sends and receives data, but the fluctuating signal is getting to be beyond annoying. Anyone else having this problem? I'm on the current version of the Frozen Syndicate ROM.

We all would like a valid reason besides spring saying "were currently fixing our antenna's."

What he said. This is very common on the Epic. Happens to me a lot =\
Running SRF 1.1.0 as well.

Someone please correct me if I am wrong, but I thought it had to do with the modem builds with the epic. I don't think it is a Sprint universal issue, because I did not have this issue on any of my previous sprint devices (that I remember).

Correct, it's the modem. That's why you see people on the forum complaining about the EC05 modem sometimes because it has signal bar issues, or stuff like that.

My phone does the same thing, even if it's sitting and NOT moving. Even my data speeds fluctuate sooooo much, it sucks. Sometimes Youtube will work great, other times they won't even start to load.

Hmmm...
It probably is the tower. Could be the modem to blame as well. Here in my house, I connect to my Airrave. 98% of the time, I have full bars with a stable connection with relatively consistent fast 3G speeds. The 2%, I get some wonky lag and usually then go and reset the Airrave. Everything works fine after I reset it.
I was just out of town in Vegas over the weekend and I had MAJOR problems sending MMS's, highly erratic data speeds, fluctuating signal, and overall connection problems. That was even when I wasn't holding the phone. Voice data and sending SMS's were very reliable, but forget sending MMS's or having good 4G speeds. I'm starting to think 4G is a drain both battery and money wise. Using 4G is like driving a classic car: It doesn't always start up, they're hard to find, they're finicky; but when it works properly, it's badass!
Random question: Is there an app that has a status bar for sending SMS and MMS's like the iPhone? For example, on the iPhone when you send an SMS or MMS, there's a status bar that shows the status of that message. If it's going out or lagging, etc. Is there an app that does that? I think that's a cool feature. Handcent just has a circular pinwheel, but stops when it goes out.

I would think it has to do with the modem as well. I have an EB13 based ROM, but an EC05 modem. I've noticed similar things, just not very frequently. It's strange...I'll have "great" signal, then for no reason, it'll dorp to 1x coverage and that SUCKS.
I'm thinking of going back to the EB13 modem as most people seem to think it's quite a bit better than the EC05 modem. I do think even that varies from phone to phone though, so I think it's mostly trial and error until you find what works best for you.

I have a fantastic update. Well it is for me, and might be for all f you also. Last night I decided to odin the EC05 modem again. And guess what? My signals beeen great!! Its always constant! No 4bars then zero in same spot no more!!
I already had the EC05 modem before I decided to do this. I recommmend odin'in you modem again!!
BIG NOTE*** I used the phone location for the modem.tar NOT pda.

I am having issues as well, i haven't been able to send any MMS for the past 24 hours. Regular texts go through just fine.

I'm having big problems with this recently in a location where I usually get very strong signal with 4G. Can anyone point me to step by step instructions of how to safely and correctly flash just the modem file?

Flash in Odin.

Any ideas
Sent from my netarchy_toast, froyo beast of a machine evo!

mine was doing the alot too but i flashed the newest radios as of 07/04/2011 and it stopped going into 1x alot

I started having this problem recently as well, I live in the Boston area. I believe I have the latest radios, 2.15.00.05.02. I had been running the stock rooted rom, which only shows a 3G icon regardless of actual connection speed. I noticed that when I flashed the Synergy Sense 3.0 ROM that my phone was sitting in 1x most of the time. I tried flashing Deck's ASOP 1.2.1 and was seeing the same speed issues. I ran a Speed Test on each of the ROMs and was getting less than 100kbps. I'm currently back on the stock rooted ROM while I try to debug the speed issues.

I was just about to post a thread on this as well because it is frustrating me a lot. when i first got the phone i was full bars every where and now , especially after rooting , I have terrible signal and most times cant load web pages or download from market unless im on wifi

I have 2.15.00.09.01 radio is that the newest

An update on my situation. My 3G magically started working again last night. I think my 3G issue may have been related to the SMS/data outage that hit the Sprint network in the past 48 hours.

What data outage did they have
Sent from my PC36100 using XDA App

All i was aware of was an sms - mms outage like he said but im still experiencing these issues. It now seems to only be certain webpages. I can't make any google searches and some websites will only load once in a great while.

Yeah I'm still having 1x issues. It sucks. So what is the new radio or a d l link for it would be great
Sent from my PC36100 using XDA App

Check my sig for radio downloads. I am currently on the newest radios, and everything works perfectly for me.
Flash a rooted Sense ROM, based on the Evo (this disqualifies MikG, Director's Cut, Synergy and other Sense 2.1 ROMs, because those are based on the Evo Shift (I've had issues with Shift-based ROMs not reactivating)
Go into EPST (Dial ##3282#, Choose edit mode), enter your MSL code (download and use MSL Reader from the Market to get it), Data Profile, hit the menu button and choose restore. Just sit there, your phone will reboot and everything will go back to default. This should fix your 3G issue.
Then, just wipe everything and flash your favorite ROM!

4G losing connection and not reconnecting

Is anyone else having this? I still have 3g connected, but if I look at the phone periodically, the 4g has an X on it (red x, im on honeyglow) it will reconnect if I toggle it, but if it drops it will not reconnect, like from 3g or wifi.
Is this s known issue and is there a fix?
Oh, and Im on the LosTKernal OC to 1.6 (stable) and Starburst 1.6, it did it on 1.7 as well.
Thanks

Which kernels have you previously tried? I tried one that made my 4g stop connecting even after switching back to stock but I did find a fix so give me some details on what you've tried so far....
Sent from my SPH-D710 using xda premium

I think I have only used ZedoMax, and then this LosT Kernel, or versions of it.
I had midnight ROM, now have been running Starburst. I think another configuration I had dropped signal on data a lot and had trouble switching between WIFI 3g and 4g. But this has helped my LOS issues as best I can tell.
If I can get 4g to work (im in Dallas, lots of 4g) great, if not Ill just try to ignore it.
If you have a fix, that would be great.
Thanks!

Honestly, if I had a choice between this and the screen wake lag, I'd not worry about 4g.
The screen wake lag is rediculous, it takes 3 full seconds to wake up with my class 10 8g card in it.

Well, what I did was Odined Crawrj's odexed with root and Busybox. You would want the deodexed version obviously. Run that in PDA slot. It will keep your data but then you will have to Odin back akernel with CWM like LoSt. It fixed all of the 4g and Wifi not connecting crap I had going on from something I triedthat had borked changes

Dropping internet connection

So I've noticed on every stock GB ROM and every custom ROM ive tried (including some early ics roms) that whenever my phone decides to switch from 4g to 3g or if I switch the wifi off, basically every time the radio switches, the internet stops loading whatever it was loading. does anyone else have this issue? It gets pretty annoying sometimes although coverage has been pretty good lately.
I could try and list all the roms ive used but it doesnt matter, the problem is consistent.
Sent from my SPH-D710 using XDA

from what i've read, it's just an inherent problem with this, and most, phones that are capable of using both networks, when forced to switch from one to the other, the "handoff" is never clean.

Ok, so I started a market download over wifi. Turned the wifi off at 10%. Now it starts trying to connect 3g first, which connects almost instantly and the download resumes. But when 4g connects a second later, it just goes to sleep and the download stays where its at until something else wakes up the 4g. Not a huge deal I guess just bothersome that it even happens.

I wrote a download manager before and made the download thread delay and re-attempt if the connection was by abolished. Maybe stock touchwiz browser doesn't do that
