Let me preface this by saying this phone was damaged. I had to replace the digitizer.
I just started using this, and flashed Pacman's latest nightly on the phone before getting my SIM, so I can't confirm or deny whether or not this works on stock. That would open up another question entirely.
My phone is completely losing all connection to the AT&T network almost anywhere indoors, and in a lot of places outdoors. I do however get complete, fully functioning connectivity in some locations.
For example I picked up my SIM from the AT&T store today, had no connection inside the store. Went outside and immediately got LTE connectivity, placed a call. After driving across the street to eat the connection completely dropped again. It returned as I got close to my job's office, stayed at full strength and then dropped off again once I went inside the building.
It did not return at any point while I was inside the building. After leaving it regained its full strength and remained at full strength, including through a speedtest, until I came inside my apartment. It has not come back since, including when I went out into the parking lot, where it previously had a strong connection.
This makes no sense to me whatsoever.
Went back to stock, so disregard the earlier part of my post about not knowing the best way to do that. I'm on raw 4.1.1 now. Still have the same issue. This is the phone status page.

Are you on the latest stock build? My Note is starting to do the same thing now on the latest stock build

No, I reverted all the way back to the original shipped build, 4.1.1.
I was using the latest baseband though when I had AOSP on there. Both did same thing.
A few observations since my first two posts. The signal strength does change of course.
Going near windows in my apartment makes the DBM go into the -90s and the asu go anywhere from 2 to 8. If the asu goes above 10 I get 3G and brief connectivity. Yet to see what the signal strength is on full LTE.
Anywhere in my apartment with no connectivity though is between -110 and -115 dbm, all with 0 asu.

I currently cant connect to 4g at my house, sprint and clear show im in a good spot for 4g but I cant seem to connect. About 3 weeks ago when I got the phone I wasn't in a covered area but it appears they just added a new tower and now I am. I didn't try to connect again before I flashed a new ROM however. Ive also tried standing outside on my deck to no avail.
Specs are attached as well as my coverage map. If we can get this fixed I'll paypal you a beer.

The coverage map for my city is completely wrong. Using Sensorly to map for a couple weeks showed what I have already observed, massive holes in the coverage here despite Sprint showing solid coverage.
That doesn't mean that's the case where you are at. Find someone else who gets 4g and try yours in the same area.
Agreed, I believe that most coverage maps are for the most part utter BS. Try going back to stock to rule out rom issues. Were you ever able to connect to 4g in a known 4g area?

if you've installed the latest OTA and wimax and you have your phone rooted, this might be the problem.

Yeah I had connected a few times before I flashed just not at my house. Im going to be going to a place where I had service today and ill check if I can connect then.
Since installing RC2 & after my wifi signal seems to be lower than it was. I can be right next to the access point & have full signal strength then just walk away 15 ft & it drops more than half. Any way to really calibrate or fine tune it?

Well, best you could do would be to re-flash RC2, or my better suggestion would be to flash to the latest nightly, as they incldue fixes for gps, wifi, and other things.
You do realize that a "bar" is not any type of unit of signal strength measurement? Basically cm7 uses different thresholds for number of "bars" displayed. The signal strength is the same.
I compared with a co-workers EVO and anothers G2 and their # of bars was 2x higher than mine. So if that is not indicative in CMod7 than that's fine. I just wanted to make sure that the wifi was still functioning correctly. I wish there was a wifi diagnostic I could run.
Yeah. Have the same problem on Nightlies 19 but if you say the strength is the same then I guess it isn't really a problem.

Just wanted to show an example.

no i agree...whenever im on a sense rom or MIUI i have almost full signal and im 20-30ft away...but ever since ive been on CM7 i can be standing or sitting in the exact same place and i'll have one signal bar and sometimes it'll even lose almost all of it's signal for a few seconds...the only time its at full signal strength is when i am right next to it...i just assume it's something with CM7 that still has to be fixed...but i definitely notice a speed difference between 2 bars and one
As stated above, use the latest Nightly. Works fine for me. Especially considering I can pick up AP's on the opposite side of a commercial building.
So i picked up a Galaxy Nexus, was brand new (almost, package was opened but never used, checked the UPtime on the battery was only mins..) anyway. im and pretty certain it wasnt hacked or anything. it was just someone trying to sell their new free phone from a contract. model number i9250m
So i brought it to my GF's house, where i have never had any wifi issues, it would show normal good bars, connect and then get the IP.. internet would work fine, then all of a sudden, nothing.. turning Wifi on/off again, would sometimes allowe it to reset, but still, nothing more than 20 seconds... when i would use it in the bathroom (router is in the landlords on the other side of the wall.) it would work fine. No other devices in the house would give any issues over wifi...
SInce it was only 4.0.2 i though i would upgrade.. so i tried the nightly build cyanogen mod rom, cm-9-20120602-NIGHTLY-maguro-signed.zip still the same issue, even at my house, nothing, unless im 2 feet from the router.. 4-10 feet and a wall, no luck at all.
after some reasearch, they said change it to 5.0 ghz from 2.4, using one or the other didnt really change anything, (i think 5.0 didnt even work) i installed wifi analiser, here is what it is showing

with this reception, wifi only works from 4 feet. and is not that stable.. when it is connecting, it is super fast, but not consistant at all.
I have changed teh channel from 6 to 11, since wifi analizer said it was a better one..
I am using AWS (wind mobilicity) network. ANyone have any input or help?
thanks

i just replaced my new gnex for the very reason you stated. the phone also got very warm while charging and took grainy pictures.
so far the replacement is doing all 3 things much better.
i would suggest trying to get a replacement.
the funniest thing, i have 2 boxes (internet with built in router) and a seperate linksys, (used as a switch) i just disabled wif on the switch and everything works! that doesn really explain the problem at my g/fs house,
this was weird, because i was hacing the same issue with my Nexus S and an Ipad.. hopefully i dont have a faulty Wifi.. thanks for the help..
That's weird. You have super strong signal. I don't know why it isn't working. Haven't seen many posts about this issue.
Hey fellow GNex'ers!
I'm currently running CM10.2 on my Sprint GNex. I just pulled my phone off the charger, set it in my car, drove home from work (for lunch), then back to work. Once I got to work (hadn't even turned the screen on since I unplugged it), I checked the battery: 88%. Now, not even 70 minutes later it's reading 82%, a loss of 6% with no texts, no screen on, no notifications, and my 3g is 3 bars, which is pretty good for where I am (and the fact that there are no notifications / data usage).
Can anyone explain what it could be killing my battery? I'll post the betterbattstats screens later (when I get back out to my car), but for the rest of the afternoon I'm going to leave it there so I can get a better idea of what's killing the battery. I'm so sick of my battery draining when I'm not even touching it!
My wife's GNex did practically the same thing this morning. Her phone died in about 5 hours, but she turned the phone off about an hour after turning it on... She's running stock 4.1.2
Edit: Lost 2% in 11 minutes, so we'll round it up to 1% per 6 minutes right now...
do you not have LTE available in your area? if not, thats your problem.

I do have LTE in my area, but I've noticed LTE takes up even more power than 3g. However, my work is at an Army post, and since the towers aren't located on the post itself, it's kind of rare for me to have a solid LTE signal. I don't make any attempts to change the way Android decides which to use though, because I find that it's fairly intelligent about switching from LTE to 3g when LTE gets low, and vice-versa.

So these are images showing that I lost 30% battery while only using the screen for 12 minutes... That's just ridiculous!

Dropped my I317 from the lift to the floor inside Subway, height is around 3m plus.
It is still working well after the drop, Screen no damage, 4G LTE network connected, call quality well.
Just the screen protector get split.
But started this morning, it has totally no signal in my office building,
I get intermittent signal loss when I back home, some time 1 -2 par, some time no signal
When I go outside buildings, signal is good with 4G speed
Is this problem related with the drop?
How to fix it? replace antenna cable or flash modem?
Thank you for any sharing!

Sounds like you might have a old modem. Setting, about device, baseband version=modem
For newer modems look here>>Section #3:good:
Thanks Bajanman,
It seems that my baseband is still there, version I317UCBMK6,
I use the following 4,3 rom I317-UCUBMK6, what should I do with the modem setting?
