Only 2G/EDGE after teardown on Nexus 5 - Nexus 5 Q&A, Help & Troubleshooting

Only 2G/EDGE after teardown
Hello,
yesterday i fixed the broken screen of my Nexus 5 (European version).
Today i noticed that only EDGE is working and that i dont recieve 3G.
My dataplan doesnt support LTE so i cant check the LTE connectivity.
I double checked the coax antenna cables and they fit well.
How can i determine which part was damaged? Or are there any suggestion what could be wrong?
kind regards

Today i noticed the HSPDA Symbol at the train station.
It seems to me that the overall signal is very weak.
I ordered a new antenna cable and hope that it will fix the problem.
Are there any suggestion what could disturb the overal signal strength?

UMTS, HSDPA, GSM Repeater? For a better Signal

Hey, I am looking for a little GSM Repeater, to get a better HSDPA Signal in my house with my Touch Diamond.
Does this already exists?
I'm not to fussy about HSDPA as I have Wi-fi but just being able to get a normal phone signal would be great, I'm sure I read somewhere about one which connects to home telephone line to get a better signal somehow. Any ideas would be great
Damian
I found a lot of antennas to get a much better signal... BUT it is made for cars... so for a short distance between the antenna and the phone.
And most of them are cable attached.....
I saw some antennas for houses, but they are too expensiv and made for a whole house and not only one room...

[Q] Signal Issues

hello all. my issue is this. i live in a area with poor signal. extremely poor actually. in my bedroom while im in bed, ill b lucky to get 2 bars. in class, i usually lose signal all together. which in turn sucks more battery as its always searching 4 a signal. do you think a different radio would make a difference? a friend in my class is on the same provider with his sa,sung galaxy s 2 and gets 3 bars in class..while i cannot even connect to the network. is it possible thi is a hardware issue?

Hi,
I notice you are on 3.6.2 XE.
Was it the same signal problems on previous versions?
What radio are you on?
There is a ril thread HERE.
Maybe you should check it out.
Don't do much efforts as i have the same signal issues...
My problem is that my room is in basement of the home.. I get 2-3 bars and its most of the time searching for a signal...
my friends have to message me first to call me coz they always
I flashed 2-3 radio files but no gain... My desire signals were better than my Sensation...
but that's for sure when you have 3 bars strength signals then it works fine... on 2 bars it won't even dial a number giving no network error...
So just live with it our buy some other set with good signals...
Poor Reception Issue
Hi there, i live in the uk and have a similar issue living in a mobile reception blackspot, it doesnt matter what network or handset you have the reception is crap. I found a solution that works for me, maybe they will have something similar out there. see here - http://www.vodafone.co.uk/personal/price-plans/network-and-coverage/sure-signal/index.htm

Weak Wifi reception

A few users reported weak WiFi signal strength on N5. Good WiFi signal strength is very important for me and this is one of things I like on my current SGS, so Im wondering how good is Wlan strength on yours N5 ?
Also Androidizen posted video about WiFi problem:
I received my N5 yesterday and i am facing this weak WiFi signal problem.
I compared it with my Iphone 5.
i was 8 feet away having my back to router, iphone 5 showed full strength signals while N5 showed 3/4 signal strength.
Ive had my nexus 5 for a few days now, and the main thing that is annoying me is the wifi, the signal is so flaky one minute im on full bars, next minute its on 1 or 2, then back to full. this can be in line of sight with the router. Ive tried a few routers at home and at work, same issue. I have tried an iphone, nokia and samsung and they all have a much better range. I'm contemplating taking this back now and getting a refund, as i don't think its acceptable. does anyone else get this constant fluctuation?
I have also noticed when you put your hand over the top of the phone the signal can drop completely. Not taht i do this, but other phones i have do not suffer with this.
i take it not many people are seeing this issue, are others with the phone able to check the wifi range and fluctuations in comparison with other devices. How can it go from full bars to 2, then back to full constantly when other phones are solid. Trying to work out if its worth exchanging for another. Speeds just change from say 72mbs to like 19mbs non stop. Thanks
Side by side with my Nexus 4 I'm getting the same strength and speed.

Do not use the bars when comparing signal.
Download an app that shows you the actual signal level in dbm. Bars can be set to whatever the developer wants. I could make you have full bars at -110 dbm which would be a useless connection, but still show full bars. For the most part, you should disregard them.
Would be possible to boost WiFi reception with a software tweak? Even if Google doesnt provide a fix, could be WiFi signal strength increased in custom roms? I hope some developer will know to answer this.
I have chance to get N5 32gb next week and I really want it, but since Im a lot in other countries, good WiFi signal strength is very important for me (to connect on WiFi hotspots)
Thanx
Is it an issue of signal strength only? Does it ever disconnect you completely? "Strength" would be much less of a concern than disconnects, now THAT would be annoying.

I have read that some N5 owners lost WiFi connection when they were about 10 m away from router. This is unacceptable IMO. I hope software tweak can boost WiFi reception.
I confirm the weak wifi too.
signal
i have nexus 5 16gb white, signal is very very weak!!! i have N4 and GN and have perfect signal!
the problem of weak wifi, is all about the nexus? we have to wait for a fix or should call google and give it back?
I'm facing the same issue. I'm few feets from AP and I'm getting weak and unstable signal. The worse thing is that it is not picking up signal from my main AP (Edimax) at home... It does not "see" the network at all even all other devices at home use it fine.
Very weak signal with this phone, I got full bars on my previous phones in my office but now only 2 bars. If you put your hand near the top of the phone the signal completely drops.
Same issue here, very weak reception. No issues with may tablet or laptops, but Nexus isnt getting good signal. White 32GB.
Yup weak signal. Initially it didn't want to connect to 3g but that was fixed with the service menu. And now I am noticing weak WiFi signal.
I'm guessing this has to do with the antenna.
Its easy to open the phone I'm going to crack it open and see what I find.
Have you folks tried going into your N5's WiFi settings & look under the Advanced submen (press the 3 dots on the lower right of screen)
Tried turning off 5 Ghz band if your router is on the typical 2.4 Ghz band - and if you have the newer dual band N router, enable your 5 Ghz band - could be interferences from other nearby devices or AP ??
Install the free app, Wifi Analayzer from Play Store & run it - take a look at your AP's signal strength, try switching to a less congested channel since the airwaves are shared, regardless which of the 11 channels you are defaulting to ...
Mine is running just fine, -60 to -50 dBm with the N home router behind 2 sheetrock walls.
Compared to my Galaxy Nexus and Galaxy SIII, I have superior Wifi Signal on my Nexus 5 to a very positive surprise...however network drop outs for Cellular connection is quite annoying...
guys try to disable the wifi optimization under advanced wifi setting and set the band to 2.4 . it worked with me :good:
I have to use my 2.4GHz connection because the phone didn't work at all on the 5GHz.

I have this problem too. Sometimes my signal is so weak that it disconnects with the router and falls back on 3G.
I tried everything. Just went into Safe Mode, but Wifi is still weak, it doesnt matter.
I tried to only use 2,4GHz and turned Wifi optimalisation off. Still the same weak signal.
I tested it with the app "Wifi Analyzer" If I stand next to the router it gets about -50dBm. Then I tested it with my brothers Galaxy S2, he got -40dBm. Thats a difference of 10dBm. -40dBm is a stronger signal.
We tried it at the 2nd floor, and he got a better signal again. So it's obviously my Nexus.
Android 4.4.2, stock, no root or something. Google come with a solution please. My previous phone had the same ****ty Wifi (HTC One X).

Terrible LTE after changing charging port

Hello,
I swapped out a bad charging port on my wifes Nexus 5. Now this phone no longer will grab an LTE signal at our house. Prior to this install this phone would have 2-3 bars of LTE at our house. NOw it just displays H.. not even H+. Meanwhile my note 4 also has 3 bars of LTE>
I tried flashing the modem.
ANy suggestions before I return this charging port to the amazon seller??
The port will have nothing to do with the LTE signal. Something got rattled when you had it apart or in data settings it got set to 3g

Are you certain about this statement? THe charging port has 2 antenna wires going to it... I am also positive that with my Note2 the charging port was 100% the culprit with the LTE . I had to send back a charging port to a seller on amazon, and buy from someone else.
I have tried switching it from 3 g to LTE>
What I have found out is if I place the phone on LTE only and then near a window... it will finally pickup LTE, but not even display the strength of one bar.

It's something internally that is messed up. You aren't getting good LTE reception so either take it apart and try to fix it or live without LTE.

[NVIDIA Shield Tablet LTE] 4g antenna module

Hi guys.
I still have my Shield LTE tablet and since few days, the GSM signal was very poor. So i decided to open the Shield tablet and I figured out that a electronic ribbon (which goes to the back cover) was cut. I don't find any info about that cable so I wonder if it's the antenna or not. The tablet seems to works without it ( Wifi working, styllus is working,gps) so my only problem is the gsm signal (stuck in H+ instead of LTE or 4G).
Do you have any idea what's is this cable ?
I can take a picture to show you
