Not to give away too much specific information, but I've got a new TMO MDA and the building I am in actually has TMO repeaters. Other TMO phones get perfect reception, and I can even put this new sim into my old unlocked HTC Typhoon and get perfect reception, yet my new TMO MDA won't get any signal.
I'm attempting to scour the registry to find some bit of info or a bit to flip or something of that sort to diagnose the issue. Our TMO rep apparently has RF engineers working on the issue, but if I can fix it sooner than they can I'd be happy.
So, basically, only these new MDAs (other new MDA owners are experiencing the same issue, as well as SDA owners) fail to authenticate to the repeaters in this building. I doubt the repeaters have a list of phones that allow authentication, since the Typhoon was never released by TMO and that can authenticate fine. So I'm thinking there is some bit on the MDAs that is sticking to one band frequency or another, or something to that effect.
Any idea where I could look for info, whether it be a web source or maybe a registry key I could tweak or something of the sort? I got the engineer mode to work (after another registry tweak to turn it on), and it isn't showing any information since the phone isn't connecting to any tower/repeater.
when you go to select networks to use, does the phone give you a list of possible cell networks?
Sorry if i sound obvious....but:
1. Have you compared the Roms on the phones? Maybe the new phone has a different rom which is causing the problem.
2. Have you tried the phone anywhere else outside your building...
3. The engineering mode will still work even without a SIM installed, so if your getting blank information then I think you have an old Rom
Hope this helps
Answers to questions in the thread:
1. If I go to select my networks manually, and it searches for networks, all it finds is the Cingular network, which I can not connect to. It won't find the TMO network at all. But I know it exists because other TMO phones work fine with full reception, and even my old Typhoon works with my new TMO sim in it.
2. The roms on all the MDAs shipped from TMO USA 1.8.10.2 and GSM rom 01.09.10.
3. Phone works entirely fine outside of the building. The building is shielded, but there are repeaters in the building for current TMO users. I know they work since other TMO phones other than the new MDA and SDAs work fine.
4. As for engineering mode... interestingly enough, now that I do have reception (I'm at home right now), I also get blanks. I thought that because I didn't get any reception, I wasn't getting anything from the engineering mode. But interestingly enough, I still don't even though I have reception.
Methinks I do need just the GSM rom. Someone mentioned it in another thread in the Wizard Upgrade forum. Where might I get just that ROM, maybe I'll give it a shot and see if it fixes before doing a full ROM upgrade (which I'd like to do for performance reasons, but I haven't gotten a definitive answer whether I can revert back to bone stone TMO roms with extended roms and everything yet).
I woould suggest getting hold of one of the phones that works, back up the registry, and restore it to the phone that doesn't work. That would tell you if its a registry setting, or a phone/rom problem

Well, there are no phones that work.
The phones that do work are your run of the mill non-smartphone phones, not a WM5 phone.
Actually, that's not true since my Typhoon is running Windows Mobile 5, but it is entirely different than the MDA.
Only all the stock MDAs shipped from TMO are failing to authenticate to these repeaters. Makes me think that updated the radio rom would help, or something on the repeaters is blocking just these two phones (the Wizard and the Tornado).
Try updating the wizard with one of these roms:
ftp://xda:[email protected]/Wizard/Roms/Tmobile/
Well, I updated the radio rom to 01.12.10...
And still wont connect to these repeaters. The phone seemed snappier to connect when I stepped outside of the building, though. So there is a plus. However, there has to be some reason the repeaters in this building are not allowing my phone to auth.
Hi guys, i know this is a common problem amongst some of us, there are several threads discussing the connection drops but please there must be someone out there who knows something about it.
Basically with HSDPA enabled, the connection will last a random period of time before disconnecting by itself and displaying: cannot connect for an unknown reason.
When HSDPA is turned off, only 3G is used, although this works fine, it is fairly slower.
I am on T-Mobile UK, I have phoned their technical support, we have established it is not the sim card but the phone itself and have tried a variety of steps to solve this, for example receiving band settings for WCDMA, this has not fixed the problem.
I have tried changing the username and password combinations and have tried every combination of every advanced network option. I have used the T-Mobile stock rom 1.43, official HTC ROM 1.66, duttys hg, energyROM, artemis 5.0 and artemis 5.5 (would recommend btw) using MTTY before every flash, and every single different radio combination.
Myself, and many people here would be very grateful for any help posted.
Thanks in advance
Why don't you try Settings > Connections > Advanced network > GPRS tab > change from PAP to CHAP.. and reset... or viceversa.. that helped for me..
Thanks for the post, i've tried all that i've tried all advanced settings, at most they last for a day or so but after a while the connection dropouts seem to worsen
Ok ive just gotten off the phone for the third time with the technical support
basically what they've said is that the hsdpa WILL disconnect because the mobile towers simply can't handle the traffic.
He said in his honest opinion I should disable it because it simply won't work well and there is no fix.
Taking the piss juuuuust a little bit
Mine on t-mobile uk will show H, but usually drop down to 3G. It won't give me an error when it drops down though.
It sounds like its not transferring from H to 3G.
To be honest, i was unaware t-mobile ran HSDPA till I got my HD2 (never showed on my BB).
mine switches between 3G and H too, this happens when the connection is being used (for example loading a web page) when the job is finished (page has finished loading) it turns back to 3G right?
are you saying that your connection never disconnects?
may i ask which radio and rom you are using?
thanks!
For my personal experience, I have for over a month, on versions 1.48, 1.66 by HTC, artemis versions, versions of other French chefs. had no problems,
Login Exchange push 24/24 without any cuts, I solicited the network with opera I passed automatically 3g H, and since February it to completely fall with the problems that everyone encounters (lost connection for several minutes , unable to connect to 3G without hard reset)
to remove the sim chip, I try with another chip of the same operator, another chip from another operator, the problem is still there.
For several days I have also continued a Touch HD, it faces no problems, no problems in connection 24/24.
In short, impossible to challenge any operator, any base station, any sim card.
It is then that the problem come from HD2:
-Software: We all try every combination of rom and radio rom possible.
It is the hardware, maybe the chip integrated into a concern for design, manufacturing concerns on some series, may be dysfunctional due to incompatibilitée between several chips of the phone, short, HTC should look into the problem.

correct, it never disconnects.
It will switch seemlessly between them, when using or not using.
same one it came with. O2 HD2.
ROM 1.43.206.4 (70315) WWE
RADIO 2.04.50.22_2
I've also been struggling with this problem ever since I got my HD2 three weeks ago. However it seems like only a few people experience this.
My case is exactly like cgrec92 described. I'm on a 3.5G network in Denmark (3 Mobile), the phone shows the 3G connection at all times. When things do work and I use Opera/weather/Twitter/email etc, the symbol changes to H and I know the data connection is functioning. I can be using this for a whole hour without any problems.
However, if I put the phone down for a while and then pick it up again to use one of its data services, very often it does not connect to 3.5G (or H) anymore. It will still show the 3G icon on the screen, but there's no data connection. Then I go to Connection Manager and I can see that data connection shows as Off - and after a few seconds it goes back to On by itself That does not mean the problem is solved, as the phone still fails to establish any data connection. What I need to do then is manually turn off data connection and re-enable it again, which makes the 3G symbol immediately change to H. Then everything starts working again - until the next time it stops working...
I contacted the HTC customer service and they said it might be a driver-related issue, recommended a hard reset. I did that and for a few hours I thought it solved the problem, but no, data connection still disconnects by itself.
I spoke to 3 Mobile's technical service and they told me to update my software, which I had already done previously (I'm running stock 1.66 ROM Danish). They also said they never received any such complains about the HD2.
Like cgrec92 I've also played with all kinds of network/band settings, but it did not make any difference.
***
One question: isn't the phone supposed to automatically connect via EDGE when it cannot connect via HSDPA? Because in my case it will only establish data connection via H, never EDGE.
Any advice is greatly appreciated!
My take on this FWIW
It's not the phone!
It's the radio ROM installed.
I live in an an area where T-mobile say I can't get HSDPA.
However, I know that I can. How? Because 3 network uses the same local cell and transmitter as T-mobile and their signal will rip your eyes out!!!!!!!!!
All information obtained from a good friend of mine who works for BT, who, service manage the cells for the networks.
Plus, in this location, the cell traffic is then handled by BTs digiatal backbone which takes it who knows where after that.
So I have a very isolated situation in which I know there is a decent HSDPA signal, but I have had trouble with drop outs on my two previous phones (Nokis 5800 and HTC Touch Diamond 2) and originally on my two T-mobile mobile broadband feeds using Huawei E220 cell network modems.
All fixed when I finally found the right Radio and flashed it on the phones and unlocked and flashed the latest modem firmware.
My broadband connections are always on and never drop out and my HSDPA signal on my HD2 is through the roof!
To further emphasise the point all the equipment is used (when home based) behind solar glass which is notorious for blocking mobile phone signals.
Land on the best one and you will get incresed battery life as well.
Bottom line is try the latest radios (2.08.50.08_02 in my case) and I think you may be surprised at the results.

I have the same problem with the connection dropping. What I did to make it work was to disable HDSPA and putting GPRS to CHAP instead of PAP, and so far I have no problems at all
Thanks for the reply and tips. I also did the same earlier today, except that I did not change PAP to CHAP :O. I was waiting until tomorrow before I posted any results, but I gotta say so far the connection has been stable just like yours.
I also called HTC's customer service in Denmark and the fellow I spoke to was very helpful but he said he has never heard about such problems. He sent me updated network settings via sms, but it did not fix the problem.
I mean, only some users around the world suffer from this problem, right? So what is it that's wrong with our devices? Is it a production fault? If I exchange my phone for a brand new one maybe I won't be unlucky again? When 3 DK finally told you the problem was unfixable, did they mention other users with the same issue? Did they ever offer to replace your phone?

Erm!
It's your radio!
But, I think I did say that in a previous post.
You had a helpful fellow who sent you updated settings?
And he thought that was going to fix your problem?
That was helpful!
It's your radio!
The technicalities are beyond a customer assistant at the end of a phone. They work from a script.
I'll send you the settings.
Have you done this?
Have you done that ?
Never heard of anyone else with your problem!
It's your radio!
T-mobile uses PAP protocol (at least they do here in the UK) and it's a handshake protocol so changing that won't really do anything to the signal definition.
You have it or you don't.
It's your radio!
There is no "production fault".
You are not "lucky" or "unlucky".
You are in an area where you will suffer from this because of the ???????
THE RADIO!
I think I have made my point.
If it turns out that you don't have a radio issue then please feel free to admonish me.
Until then----------
It's your radio!
well I don't mean to sound rude but do you SERIOUSLY think we haven't tried that? ive tried every possible radio available here and every different rom, so excuse us for trying new things.im glad your not having any troubles yourself because it is really annoying
perhaps you could post us your rom and radio?
I don't suppose you could post us your settings in advanced network?
did you use the connection setup?
thanks for your help
Yes, I was about to mention something similar. I haven't tried combining different ROMS & Radios myself, but I know people like cgrec92 who have with no good results.
And if it is the radio, then every 3 Denmark user like me would be experiencing the same problem, correct? I don't think that's the case. Actually when you read the forums you will find users from different countries with this problem, and they/we are not the only ones with a certain combination of ROM/Radio.
So yes, by disabling HDSPA I finally managed to have a stable data connection (but no 3.5G, obviously). At this point no one seems to know the cause of this issue, but I suppose it's naive to expect a future ROM to solve it, after all it's not a widespread problem. Is HTC even working on it? Are we sure it's not our devices that are faulty?
I honestly have no idea, but I cannot just accept this problem and live with it after all the money I put into this phone. That's why I brought up the possibility of having it exchanged for a brand new one in hopes that it will not have this problem.
Any ideas?

I referred to my radio in my previous post -20.08.50.08_02.
My OS ROM is Leo Lite 3.
Connection setup used and no further settings.
My explanation for this is the fringe nature of the received signal.
The radio its constantly 'hunting' for a signal and the radio software has difficulty in locking on.
BTW OS ROM and settings ready don't affect the efficiency of the radio signal.

I appreciate the help, but he doesn't seem to understand the issue here. It's not that we have low connection, or that we cannot connect to the 3.5G network. The problem is that the phone's data connection will automatically disconnect even when we are in an area with full 3.5G signal. The phone will connect for a while and then, moments later, in the same spot and with full signal, data connection is terminated. So I just can't see how the radio has anything to do with that, especially when there are hundreds of other users out there with the same ROM & Radio as us and in the same network. And yet they do not experience this problem.
Ive have similar issues but it depends where i am it appears that some towers its ok where others its not!

The radio differentiates between all the different levels and types of signal and it depends on how exact it interprets the signal. They are supposedly optimized before release and then re optimized with each newly released version. Network operators then have their own network parameters and again the radio has to accommodate this as well. One radio will never satisfy all these criteria and some of you will be in the wrong place at the wrong time on the wrong network with the least effective radio.
I can assure you that I most certainly do understand the problem and that is why, in my own case, I have resolved it.
Hi All,
For 2 weeks or so now I've been having an issue with my Hero's internet connection. Didn't notice specifically when it started as it only affects the 3G connection and I mostly get HSDPA in my area. I use WiFi at home anyway.
When the notification bar shows 3G, the upstream arrow flashes periodically but there is no traffic downstream. Market downloads fail, anything which requires an internet connection will timeout.
However as soon as it switches up to H connection, it starts downloading immediately. If I switch to 2G only GPRS and EDGE connections work fine too.
Around the time the issue started I was trying a few different 2.1 roms for the first time. Have flashed several different roms since and have the same issue. Currently using VillainRom5.5. I was already using Radio 63.18.55.06JU_6.35.09.26 but have reflashed this too. Have flashed the stock Orange RUU, RUU_Herrange_UK_2.73.61.5_release_signed_NoDriv er.exe, but the issue remains.
Didn't have a problem, especially at home, before trying the 2.1 roms. I have good signal regardless which connection I have, currently 3 bars.
Thought it might just be an issue around my house but have tested all over and it's the same. Became an issue this week as I was visiting Somerset and in area's without HSDPA. Had to switch to 2G only in order to get internet connection.
Have searched here and other forums but cannot find anything specifically like this, any help greatly appreciated!
Cheers,
hello,
I had a lot of problems with connections (3G/HSDPA/2G) with loose of signal.
I tried a lot of ROMS to solve this problem. But It wasn't the right way...
In fact, My SIMcard was defective. I had to change it, and now all is OK.
I'm not sure that it will be the right issue for you, but perhaps It could be...

Cheers for your reply.
Have contacted Orange today, the customer services guy tried some stuff and asked me to test and call back. Hasn't helped so will call them back in a mo and report back.
Hi,
I am having a very similar issue and I am also on Orange. My issue started after around the time I flashed Villian 5.3 but I doubt this is the issue as I have flashed other ROMS since and have the problem. Have you also done the 2.1 battery stuff by *#*#4636#*#*? I did this around the same time the issue started and I thought it was because I had set it to GSM (auto) but I put it back to WCDMA but that made no difference.
My phone keeps showing 3G then swapping to HSDPA. This is both an my house and in the city. I always got H no matter where I was but now keeps swapping after a couple of mins or when I use internet. I've reflashed ROM, radios and tried a friends Orange SIM and I get the same.
I also have the exact same problem on the 3 network in the uk, definately not a sim problem as before I rooted and flashed it all worked perfectly. Hasnt been too much of an issue as most of my city has hspda coverage but if I go out of town its a pain.
Problem started as soon as I flashed a villain ROM and is present in all 2.1 ROMs I have tried although I have noticed that the legend ports seem more stable and connect a little better, so am currently running the villain 4 ROM. Updating the radio made no difference and I am starting to wonder if it is some thing to do with using a CDMA port?

Yeah I did try that stuff, I too have set it back to WCDMA Preferred. Now you mention it I guess my issue did start around this time too so its likely to be linked.
It does seem too coincidental that we have done the same things and are having the same issues on Orange. I'm going to wait to see if ROM from the official 2.1 build sorts it out and if not swap the phone out. I've had Villian and now BeHero + and still have the issue. I've flashed different Radio's as well and that has not fixed it.

Ive had this problem for well over a month now, way before the gsm auto trick came on the forums and I started using it, I dont think thats the cause, dont think its a radio issue either as had it on two diff radio versions.
My issue started as soon as I flashed a eris port which as far as I know is cdma based and isnt that a different kind of network than we use over here??
Any devs want to chip in here and help some noobs plz?
I've always had this issue with Orange as well, regardless of ROM, prior or after to flashing. I thought it was just the Orange network capacity as when I use the phone out of peak hours (2-7am) its fine.
I have the stock Hero with 1.5, no roots or custom os & it happens to me on Orange UK.
No idea why, but don't think its to do with custom roms!

Yaeh i have the exact same issue, tried many different roms, including official orange roms. This issue started before i started playing with customer roms.
Anyone have any suggestions?
Just adding to the list. Same issue for me, Orange UK - not specific to any ROM (Stock or Custom)
I'm going to join the party and say I have this problem too.
Although I didn't notice until I read this and checked, I just assumed Oranges 3G network was unstable in peak times

I too am on orange uk and tried this and experienced the same issue.
The solution is just reflash rom and radio (no wipe etc so data remains). That fixed it for me.
Also don't mess with *#*#...... settings
I'm still having this issue, maybe it is just the Orange network thats to blame? Seems to be to a number of us cropping up.
Gonna get back onto Customer Services this weekend, see what they say this time.
Same problem here. I'm on Orange UK too. Seems like an Orange network problem rather than a ROM problem
Saw this on my G2 Touch Hero on t-mobile when using villainrom 5.2. Not seen it recently and don't think its related to flashing 6.0.

Thought I'd update this.
Been living with the issue since posting, tried a few roms, all with the same issue.
Tried the latest radio, that didn't help.
Flashed EzHero rom few days ago and 3G has been working fine since! Don't know whats in this rom which might do that, it doesn't display the 'H' icon anymore which is the only visual difference. Might just be coincidence but either way glad its working consistently again.
I've had the same issue here on the other side of the pond in Canada on the Telus Hero. I think it has something to do with the phone trying to default to the fastest connection. I'm assuming the providers don't want us connected to the faster networks constantly, so they have a disconnect on idle response; which in turn is being counter-acted by our hero's need for speed. That is one theory, but I have to include that when I first got my TELUS Hero, before rooting and installing MaDaCo 1.5 I would have stable 3G connections. Any ROM installed following the root of my phone has caused this same dilemma.
This is a big issue on orange one which I have never got to the bottom of.
Now my phone seems to work 99% of the time but it always switches to H before downloading.
It might be something to do with Orange switching to new "next generation" towers. Apparently last time I phoned orange my phone was connected to two towers (only supposed to be one) so it was impossible to triangulate my exact position.
This might have something to do with it.
I did a little searching around but didn't find much useful.
Anyways, About a week or so ago my HD2 running ChuckyROM-23125-Tabtastic.Jun.30.sfx, started displaying only the E for Edge data speeds. Normally, I would always have an H.
Any help?
May be the Rom, were u always using this Rom? Do you have the latest radio or software update? If not try updating your software or radio for your band. You can also try a different Rom to see if you have the same issue.
Good luck.

That's odd that it would start acting that way out of the blue (which is what you're thinking, I'm sure lol).
I don't know for sure what's causing that, but here's where I'd start:
-Make sure that your network settings on your data connection haven't somehow gotten switched to "GSM" instead of "WCDMA". If you see the setting is at "Auto", then go ahead and select "WCDMA" and see if that clears it up
-How old is the sim card in your HD2? If it's more than a year old (i.e. you brought it over from your previous phone), you might want to get a new one from T-Mobile...it seems that older sims can have compatibility issues with the new HSDPA network that's being rolled out.
-If neither of those two help out, then try a flashing a different radio (just do NOT use any .51 radios, those will brick your US HD2). I know the one you've been using has worked fine until now, but again with the backend changes Tmo is making on the network, it's possible that the one you have just doesn't do as well in your location anymore.
Other testing methods I'd suggest include seeing if you have the same issue in other areas than you're usually using, and also see if anyone else you know in the same area on Tmo is having the same problem.
i believe it may be my SIM card. It is over two years old and has been on every phone i've owned(about 6).
Also, i couldn't find anything about changing from GSM to WCDMA, only something about enabling and disabling HSDRA/HSUPA

Yes, I'd def say it's time to get a newer sim Please post back here and let us know if that resolved the issue.
In the settings tab on your slider, click on "wireless controls", then tap the "phone" entry (not the swich, but the bar to the left of it), and on the following screen scroll to the bottom and choose "change baseband"...then you'll see the options there under "network type."
Hello everyone!
I am having a very hard time diagnosing an issue with my Nexus 6P. Android 7.1.1 Angler-03.78 Build: N4F26T on AT&T unlocked. My network keeps dropping consistently. It works fine for about 5-7 minutes after a reboot or after toggling Airplane Mode. It goes on to attach itself to LTE and then subsequently drops to HSDPA/3G and then just outright loses network. It intermittently then comes back but usually hangs on to HSDPA/3G and the voice quality and data speed are just terrible.
I tried the SIM in my old Galaxy nexus (which doesn't support LTE unfortunately) and the network didn't drop. So I am convinced something is going on with the phone. This issue crept up this last Monday (03/26) and has been going on ever since. Has anyone had similar issues? If not, could anyone tell me how to diagnose this issue before I have to send it to Huawei? Because I am not very keen on sending away the only proper handset I have.
Thanks
I had a similar problem on Cricket, which uses AT&T's network. I never had good cell coverage in my apartment but it suddenly got so bad that I could only make and receive calls in certain rooms. Cricket wasn't able to diagnose the issue and I ended up switching my service to Project Fi. The problem completely went away. I now have a strong cell signal with full bars everywhere in my apartment. I'm not sure that sending your phone back to Huawei will actually solve anything but good luck.

Oh, I can't switch from my carrier. And this particular issue just started occurring this week. I have been reading a few threads with different radio versions. I wonder if that will help.

Hello everyone!
I am having a very hard time diagnosing an issue with my Nexus 6P. Android 7.1.1 Angler-03.78 Build: N4F26T on AT&T unlocked. My network keeps dropping consistently. It works fine for about 5-7 minutes after a reboot or after toggling Airplane Mode. It goes on to attach itself to LTE and then subsequently drops to HSDPA/3G and then just outright loses network. It intermittently then comes back but usually hangs on to HSDPA/3G and the voice quality and data speed are just terrible.
I tried the SIM in my old Galaxy nexus (which doesn't support LTE unfortunately) and the network didn't drop. So I am convinced something is going on with the phone. This issue crept up this last Monday (03/26) and has been going on ever since. Has anyone had similar issues? If not, could anyone tell me how to diagnose this issue before I have to send it to Huawei? Because I am not very keen on sending away the only proper handset I have.
Thanks

This is a known issue just this month I experienced it myself, Try flashing different radios I was on 03.78 and had signal drop issues 03.72 and 03.75 have had the best results.
I flashed radio 3.7.5 and it did zip for me. I was on Sprint where I never had any problems and switched to AT&T when I got the 6P and never got more than half the bars strength when the service was actually working. After I switched to Project Fi I am usually on the T-Mobile network and get full bar strength 100% of the time at home. If I use Signal Spy to manually switch to Sprint I still get full bar strength in every room in my apartment. This is with the exact same radio that I had problems with on AT&T. I don't know if the 6P doesn't play nice with certain networks or if those networks provide inferior coverage but Verizon users have had notorious problems with this phone that caused Google to issue a separate radio just for them. Verizon customers are the ones who claimed to benefit from flashing radio 3.7.5. I have never heard of that actually helping anyone else and it definitely didn't help me. If the problem is partly with your network then sending the phone back to Huawei won't make any difference. You can try flashing a different radio but in the end you might have to switch carriers and if you can't do that you might need to switch to a phone that your carrier actually recommends.

It's strange because this happened just this week. It was fine before this week. Everything worked, I got proper signal strength and the connection never dropped. Now on my commutes I can see there is no network when I am driving, no maps, no spotify nothing.

Okay, I guess that's what I am doing today. I haven't modded my phone in any way, I am still on stock android. I am going to have to start by unlocking bootloader and flashing TWRP.
Good luck. I was in the same boat. It just stopped working but there was no Rom update that could have caused a problem.

Where do I find the old versions? This thread doesn't have the old versions anymore. 03.79 doesn't resolve the issue.
EDIT: I used 03.75 and that doesn't do it either. Time to try 03.72. I am so disheartened.

Nope, no luck with 03.72 either. :crying:

Why not go to AT&T first, let them know about your issue and have them provision a new SIM for your phone (free). I seriously doubt a different radio is going to solve your problem, but if you want to try there is a dedicated thread in General for flashable bootloader/radio zips, but you would be better served installing ADB/Fastboot on your PC and using fastboot to flash them yourself. The latest radio is 03.81 (from 7.1.2) The stock image files on Google contain the radio and bootloader img files. If the new SIM doesn't fix it, you may end up backing up your data and doing a factory reset.

Okay the latest factory ROM didn't work, I did a complete wipe and a factory reset. I will go to AT&T tomorrow and see if a new sim helps (I doubt it because this SIM works fine in my backup phone Galaxy Nexus but I can't verify LTE with that).
I don't know what my options will be after this. I feel like I am spending more time maintaining my phone instead of using it. Just disappointed, that's all.

Yeah, I found it. Thank you. None of the versions helped though
I've been experiencing signal problems when downgrading which is not your case. But I got it solved by performing a factory reset. It's fairly straightforward once you have backed up your data. Worth a try?
Similar problem here I think I have found part of the problem
I have been having a similar problem ever since a recent update. I have tried everything found in this post. Recently I tried turning off my wifi and noticed the problem seems to go away. I have done a few searches to see if anyone has reported no phone with wifi on, none of the results so far have been very helpful.
Since I don't want to be without wifi, I have gone into the developer options and turned on cellular data always active, to see if this helps, so far this is working for me.

I did try that but it didn't work unfortunately. I called up Google and they sent me a refurb which was DOA but then later they sent me a new one which works just fine. So it was definitely a hardware issue on my old phone. I don't plan on updating my software because I just want this phone to work like a phone.

It happened either way. Wifi status didn't affect my issue. It used to die out completely. Google just sent me a new replacement (after a DOA refurb) and it seems to be holding. But I am not upgrading to 7.1.1 because I feel the issue might crop up again. So I am going to stick to 6.0 for now.
Update on my status
So far having wifi off has worked, until I ran Waze and then both GPS and Networking down till I quit and turned Airplane mode on and off. The previous change to Developer setting did not work.
I have been debating going back down to 6.*, has anyone had good results with this?
