Lost Signal, Never Came Back [Fishing]

I'm just fishing for some others who might have experienced this problem, and then for any possible solutions.
Short: When I lose signal for an extended period of time, it never comes back. I have to perform a reboot or turn airplane mode on and off (which seems to take around 2-3 minutes when this issue occurs) for signal to return.
Long (to give you a better idea of what I'm talking about):
The other day I visited the Marine Corps Museum. While inside, I lost signal. After about an hour or so we left the museum and headed towards DC (that's Washington, D.C. - the nation's capital and one of the best areas to be a T-Mobile customer).
I hadn't tried to use my phone since I had first walked inside the museum, but about 20 minutes after leaving I pulled out my phone to text message a friend and I noticed I still had no signal. I waited for a minute to see if the signal would come back, but it never did.
I rebooted my phone and my signal returned (full bar HSDPA).
I know I wasn't in a bad signal area. I was on Route 1 North, which I know for a fact has great data coverage with T-Mobile. There are a couple of spots on I-95 that drop signal, but it's usually between Fredericksburg and Stafford for about 0.5 miles (I was nowhere near there).
Has anyone experienced a similar issue?

I have this same issue daily. I do not get a signal at work and have to reboot or turn airplane mode on then off to regain a signal. It is frustrating to say the least.

I'd like to draw your attention to those two threads: http://forum.xda-developers.com/showthread.php?t=632552 and http://forum.cyanogenmod.com/index.php?/topic/1599-loss-of-signal-no-reacquisition-issue/
Right now I'm logging the output of logcat to SD card, waiting for the issue to reappear... it would be awesome if we had a way to reliably reproduce the issue, but so far, I didn't find one.

Dropping Signal

Hey there people.
Hoping I've not missed an existing thread.
I'm having problems with X10 dropping its signal seemingly through its own free will. Had phone since mid april and not had any problems with. But the other week me and the missus noticed occasionally i wasn't receiving texts she had sent me. This happened every now and again for a few days. I then noticed when i picked up phone it'd show signal on 3G as maybe 2 or 3 bars then suddenly drop too nothing, showing the little x indicating no signal. After a few seconds up to a min it'd pick signal back up and work again. I no for a fact its not me been in an area without 3G coverage because it happens at work and until this started happening i got a strong 3G signal there. It doesn't seem too switch too edge either any more. Its set too GSM/WCDMA prefered. I'm on 02.
Anyone else have similar problems or any clues on what the problem it.
Cheers

No internet on edge PERIOD!!!!

I hate to ask this........if its in another forum or not but do you guys have the same problem running your internet when you are on edge. What sucks is my house switches from H to E and when on E there is no action. If there are others let me know cause I this is my second phone already due to black screen.

I get internet access on edge... it's slow but it works.

I'm having the same issue with the edge... I'm in Salt Lake City, where are you?

Same here, in southern Arizona. This is also my second phone. First one bricked mysteriously I can't access the app store or do ANYTHING data-related in EDGE mode. 3G works very well, but I get nothing whenever I'm in EDGE. At least I have wifi at home.
I've called customer support and their recommendation was to do a factory reset. I tried that, no improvement. I get slightly more stable connections after changing my radio to GSM (auto PRL) in the phone information menu, but it's still awful.
I'm thinking of calling back again in a week or so and bugging them to give me a third phone. Maybe the second batch with tighter hinges will be out by then...

I am on my third G2 and all of them have had much the same issues. All have had loose hinges. The last one I received started out by rebooting on its own as I charged it. With my Nexus One and my Vibrant I always get 1-3 bars of 3g with the G2s I get virtually no H consistently or 3g and 2-3 bars of E or a lot of G. This last one will go from suddenly having 4 bars of H to 1 bar of G it just does not stay on H and I get numerous No signals. Getting on the market at times is frustrating and downloading is a real adventure. I like the phone but am becoming disenchanted as it seems with this last G2 I am uncovering different problems every day. I have had black screen freezes random reboots etc. Also while in a conversation on the phone it put the call on hold without my doing anything. Perhaps the sensor malfunctioned and my ear hit the hold or mute button but this should not happen. I have also dropped calls and have had calls come in with no notification except for notice of voice mail after the fact. I am about ready to throw in the towel and send it back for a refund. If anyone has any ideas or fixes for any of the issues I have mentioned I would greatly appreciate hearing them
Just had a screen freeze and when it booted backup by itself it just went into a loop of home screen to black screen and home screen to black screen. Had to power off and pull battery and reboot and it now seems okay. That probably does it for me. I am tired of the constant problems and after 3 devices all with similar or same issues and more being uncovered every day,I am coming to believe that another replacement will not be the answer.

Yes this happens to me pretty often. I live in a building in Brooklyn NY, and when I am moving around in the building, my data connection goes out and I get 5 bars of signal but no data, no G, E, 3G or H+.
Also if I'm in an area where data connection or the signal is spotty, it will go from H to E and then back to E, and then give me a error about not being able to get any data connection.

[Q] Signal bar goes from full to nothing randomly

Ever since I got a replacement phone Ive had this issue- while on the Sprint network my signal will randomly go from full to nothing at all. Yet when I use roam control to go into roaming, the signal always stays at full strength
The other thing I noticed is that when I dial into the 3282 menu, someone elses username is there instead of mine. When I run connectbot and use getprop, no MSL # is there either
Anyone know whats going on with the phone and if this can be fixed?

getprop ril.MSL
It is filtered from just getprop.
My signal has always done that.
Updated profile may fix the user name?

Thanks that command did the trick to get the msl- I was able to go in and manually change the username now.
Is there any settings in the data menu to improve the signal? Its almost like its jumping back and forth between a good and bad tower?

Not that I know of. That is what I suspect is the case with me as I have about 3 towers that are surrounding me from various sides and I think it is hopping between them... not sure there is anything to do for it but I haven't really seen any ill effects from it.

The weird thing is it never used to do this before when I first got the phone. When I was in the same areas the signal bar was always full and would never drop. I wonder if its a tower issue or something they changed with an update.
Sometimes when people call me they say it goes straight to voicemail though which worries me

Could be the modem. Some people think el30 is not as good as ei22 or ec05. Maybe try some others.
For calls calls going to vm, that can happen if you are using data in a 1x area. Also can happen if you have accidentally switched on ddtm in call settings.

This is going to be plain and a tad bit retarded but a solution is WiFi, as far 3G and 4G mine has always done this but i can testify that in my house i used to get ****ty service like 0 to 1 bar when i was on EC05 i switched EL30 now to FB15 and say much more improvement more consistent to 3-4 bars.
PRL updates could help if you roam around there. newest as of today is 60685

I've been having this problem too for about two months now. But as you said roaming works fine so I just assume it's a sprint tower issue and force roam whenever I'm on wifi.

I have had this issue for a year or so... started a while after I first rooted.
You can hold my epic in one hand, my wife's epic in the other... her bars stay steady, maybe fluctuate between 2 or 3 bars occasionally... mine randomly and erratically jump from 2 or 3 to nothing, stay there for 30 seconds or so... and jump back up.
While its annoying and distracting, I've never had a problem with dropping calls or losing data. I even took the phone apart to make sure the antenna had not come loose. Problem persisted over several roms and several modem Odin flashes, just won't go away!

Mine does the same, it'll have full bars, drop down to nothing, but my 3g/4g still work fine (off wifi)... i just ignore the signal bars because most of the time my data still works, albeit a tad slow.

[Q] Nexus 4 wifi range / bars issue

I have a nexus 4 16 gb rev 11 running 4.2.2. it seems like I have a weak wifi reception both at my workplace and at home.
1. When I'm at work 5 meters away from the router. the values I get from wifi analyzer keep on changing constantly from
-54dbm to 66dbm and the bars go from 2/4 to 4/4... Speedtest had good results (26Mbps down/29Mbps up).
2. I walked around the office, on the same levels of reception other devices (S3,S2,S,HTC desire,Gnex) showed more wifi bars. confusing...
3. When I put the Nexus 4 right next to the router it gets -24dBm. (speedtest 26 down/31 up)
I have 3 more days to replace my device and I dunno how to make sure it's just a software issue or a hardware issue. I dont understand
how come the bars keep changing on the same dBm levels that also change rapidly in different locations (I can stand at the same spot and get -71 and then -52 and get from 1 bar to 3) .

It could be the way you hold it. The antennas for the N4 is in the back panel. The wifi antenna is located at the bottom rear of the phone. A slight change in holding it (moving a finger) can make a difference. Also, some router antennas are directional, which could explain the slower speed when placed next to the router.
Hope this helps >.<

I tried just now to put it aside on a table and see if the values change and they still do even without me touching it,
I'm in my room right now and it changes from -90dBm and then -75dBm and then after a few seconds -88,-84,-82 and back to -75,
then again it goes back to -90dBm. In this location I get just one bar or no bars at all but the internet still works even with no bars. Why does this happen? =[
