My MB865 (Atrix 2) started losing signal and restarting. When it does re-acquire a signal, it is always a strong signal (5 bars ~ -65-dB). The problem has been getting worse and it is getting more difficult to acquire/retain a signal. Often the phone will spontaneously re-start as well. The re-starting seems to happen more frequently when I am charging the phone or do not have a signal.
My son has the exact same phone with the exact same configuration, and his is working perfectly. Side-by-side, he will have 5 bars while I'm not able to get a signal at all.
I have been told that this is likely an antenna issue, but I'm truly not sure.
Could a faulty antenna cause the re-starting issue described above? If it is a faulty antenna, is this something I could replace myself? I was unable to turn up anything useful in my search for a replacement antenna for this phone, so I'm not sure where to even get one.
Thanks in advance.
I am having nearly same issue with my atrix 2
I cant make or receive any calls/sms
The signal reception have decreased a lot.
I would like to know what you did to fix the issue

I bought a different phone.
Because I love my new Nexus 5 so much, I "had" to go swimming with it for about 10 mins until I *realized* it's not water-proof. :silly:
Anyway, I opened it up and did my best to save it. And it boots up and functions again. :victory: However, there are three sequels:
1. LCD display shows water streaks in the background and the contrast is bad but can still see;
2. The vertical center line of the touch sensor doesn't seem to work; Elsewhere works fine;
3. Very weak WiFi reception and hardly be able to connect to any wifi network unless it's in the proximity of the router.
The first two problems can be "easily" fixed by replacing a new digitizer/screen assembly. But the #3 is the most critical issue. If it's not fixable, this phone is pretty much useless to me.
I've read that many people complained about the weak wifi issue on Nexus 5. But mine was very good and always had strong signal before it went swimming. I've tried cleaning up the WiFi/BT circuits and even made sure to have the WiFi/BT antenna on the back cover to have good contact with the contact pin on the main board. But still got weak reception.
Has anyone had similar issue and how to fix weak wifi reception problem? Or where can I get it fixed?
Thanks a bunch!
Hello guys and girls,
after experiencing some GPS problems (loss of signal on the road and/or late fix) I did the fix found on youtube (Where you place a bit of paper/tape under the GPS antenna contacts). It worked just fine, my GPS fix is now happening faster and I did not lose the signal ever since. But I am now facing some (weird?) problem: My GSM connection (GRPS, EDGE) is really really bad. In my room I don't get any signal at all, outside I get like 1 out of 4 bars of signal strength, but I lose it after a few seconds. I normally have 4 out of 4 bars in my room. BUT: My 3G connection works fine, 3G, LTE, same connectivity as before.
My friends phone (same carrier) does get the full GRPS/EDGE connection in my room, so it's not the carrier having problems. I didn't do any updates or anything in the last weeks. It would be a huge coincidence, if a software bug happened while I fixed the GPS problem, so I assume it's a hardware related thing?
How might I fix that, what possible solutions are there?
Tried the following so far:
Restarting multiple times, with our without airplane mode
Re-inserting the sim-car
Switching between LTE only, GSM/LTE, GSM only
Flashing new/other modem
Replacing the speaker/antenna-module
-> nothing changed
out of sheer curiousity, and after reading your post, im stuck wondering.. why do you want or need your gprs and edge connection when your 3G/LTE is fine? data speeds are very slow, and drain lots of battery using anything internet or download related..
Yeah, sure, 3G/LTE is better and coverage is really good where I live, that's why it's not an emergency for me, but it's very important to get it back to work properly.
I know at least 2 situations where I really need GSM (GPRS,EDGE):
1) At work (huge metal building, no 3G/LTE, only GSM) -> I can't call, text or do anything with my phone (don't worry, I am allowed to do so and no, there is no WiFi)
2) On the road, especially the german autobahn has large areas where there is no 3G/LTE coverage, so I can't use my navigation-software properly and can't respond to calls or whatsoever
So all in all: GSM in really important for me. Please help me. :crying:
ahh.. I see.
and your GPRS/edge was fine before the GPS "fix"? maybe something got loosened?
Before I did the fix it worked perfectly fine. Directly after I did it, the gsm was gone so I figured that I somehow damaged the antenna. But since I replaced it and nothing changed I am not sure what to do now. Are there other antennas, are there other modules that influence gsm, that I might have damaged or loosened?
That's what can happen when you tinker with guts of your phone. You risk damaging or messing it up. Sorry, I don't mean to sound like a jerk.

Yes, dave2metz, I know. I was fully aware of that when I opened my phone for the first time to fix the GPS thing. But I am not here for moral advice.
Any ideas how I could fix my problem are highly appreciated!
Edit:
Just checked: The sim-card is not the cause of the problem either. I would really appreciate some good ideas guys..
No idea what I might try?
My best guess is that this is a hardware related problem. But how does one fix it? I replaced the antenna (the bottom thing), nothing changed. So that specific antenna was not the cause of the problem.
Are there other antennas?
Are there antenna-connections that I could check?
Any other hardware things that I might check?
Anything that might have lost the physcical contact inside the phone because of that GPS fix?
Could it, against all odds, be a software problem?
Please, I am really in need of a working phone. If I can't fix it I need to replace it sooner or later because GSM is essential.
If anyone can provide me with an idea or something that leads me to a fix, I will reward you (amazon gift-card or whatsoever).
Cheers,

Did you figure it out?

Did you end up figuring anything out for this? I have something along the same lines. I dropped my phone and smashed the screen. I was able to get a guy to replace the screen portion of the unit, but immediately after I got it back it had no cell reception. Rebooted came, back thought everything was cool.
After a couple weeks I notice my phone has lost reception occasionally. It's now gotten worse, I used to be able to reboot it about 5 or 6 times and then it would randomly come back. I've even had it come back without performing a reboot on its own.
I ended up taking the whole thing apart, reseating everything after having a day and half span where I have been unable to get it back and boom reception came back. Thought it was his repair job at that point, but it has since dropped the signal again and I can't get it back. Yesterday even I was showing LTE signal changing from low to strong etc, but my network was still down as I couldn't perform a search, maps, or anything.
I have my phone apart again. I've checked all the connections over and over and wondering what else to look for or try to replace. True my impact could have damaged a component on the mainboard, but my phone works fine in all other areas. I could replace the antenna wires and the antenna/speaker module, but I'm not sure it just a reception problem.
My phone also boots into airplane mode when it has no signal, but turning it off does not restore the connection or anything. Rebooting it puts it back into airplane mode. *#*#4636#*# shows my radio is off. Thinking it's a short or something somewhere, but I doubt I'll be able to fix it in that case - at least without a mainboard?
That's my other question, what part need to be replaced for experiencing no network and its not the antenna or antenna wires? Is the mainboard? Sister board? Currently researching teardown as this phone is modular and I'm sure I could source the part off ebay or something.
Hi,
There's one antenna for 2G/3G/4G so I think if this problem was caused by hardware, it would affect overall connection to mobile network.
I think that this might me software-related problem but actually can't figure out which. Only thing I'm currently thinking of it that your phone has problems with connecting to certain GSM band. For example in Europe are 900 MHz and 1800 MHz standard for GSM.
Lower frequencies bring you better coverage. Your phone might have trouble with connecting to them and automatically selects 1800 MHz layer.
If you are able to get another phone with SIM of the same network provider, I recommend you to download any networking app and compare data about cells. Mainly CID number. It's unique identifier of each cell in an area.
If both phones are connected to same cell (CIDs are equal), you have to compare RSSI values. Lower means better signal. RSSI is defined as a negative number in an interval of <-51; -113>. So -75 dBm is better than -89 dBm. In one place should be difference about +/- 5 dBm.
Reaching slightly different RSSI numbers while connected to same cell in same place might mean that your phone really have problems with radio.
hey mate,
My wife phon is having the same issue 4G works, 3G sort of works, 2G nothing.
[Did the GPS fix on my wife's Nexus 5 (and mine) also]
swapped sim, used another telco same issue.
when into service menu did *#*#4635#*#* , click the 3 dots, select radio band - only see USA band.
While my phone had automatic, usa bad , usa band, japan band.
she is running stock rom with unlocked boot loader, I am on CM11 but doubt that should make any difference.
if I work out what is going on will report back.
nexus 5 3g 4g damaged
hello guys?.. my htc nexus 5 got wet and i notice the signal strength got lost. when i open it up i notice the lines on the antenna got damage. how do i repair it? or should i replace it with new one? Pls help !!
Is issue still remaining?
Hi. I am having the same problem. Could anyone find a fix for this?
My GPS was and is fine. I didn't do the gps fix, but I have replaced my battery and I think it happened after the replace...
OK so I replaced a cracked screen, easy enough.
Now I get very poor cell reception. If I'm in a strong signal area it connects OK but the signal goes from full signal to none all the time.
This problem did not exist before, I had never seen the red X on the signal icon before.
Have checked all connections etc and done a restore but still the same.
I know I had to remove and replace the antenna module to replace the screen, I was careful not to damage it.
Any ideas or anyone else had this ?
Cheers

did you ever get this fixed? if so what was the fix?
I bricked my phone, sent it to an authorized repair center, they replaced the motherboard, display and battery and sent me the phone back.
Phone is working now, but GPS doesn't find ANY satelites and 5GHz wifi drops connectivity just 2 meters away from the router. Am i tripping and being stupid, or they really forgot to plug one of the antennas back to the motherboard? It just sounds like it, what else could it be? 2.4GHz works fine, Bluetooth works fine, 5G cellular cant tell because i have to root my phone (non supported country). GPS module seems to be working, it just acts like im burried underground, not finding even a single satelite. Wifi 5GHz i get full signal only when i put the phone on top of the router. 1.5-2m away and it drops connectivity completely.
Just do another RMA. lol
It sounds like they either did something wrong or there is some issue with the new motherboard.
You must have hired a inexperienced person.
