My original OnePlus One worked great in my area, my Moto E also get's signal all the time so this is not a network coverage issue. I have an OPO that will let me make calls perfectly with great clarity, and then a moment later will say it does cannot find a signal. If left on it will mostly have no signal but after a few power cycles boom there you go, full signal! I would think it was an antenna issue except when it does work I have full signal, not a weak signal like on my old S3 with antenna issues.
I am hoping this is just a modem issue that can be fixed by flashing the latest stock rom/modem but I am hoping I can get some input on the problem.
Thanks for your time!

have you dropped the device? it could be hardware.....too. Have you tried different modems or not? If not that would be a start. (https://forum.xda-developers.com/oneplus-one/general/firmware-modem-oneplus-one-t3462214). If the modems dont help then here what i would check...only if you confident.
Open the OPO and make sure the screws have not come lose as sometimes that can cause issues with signal.
Recently i has something similar but no as bad as you, i ended up replacing the, Speaker Antenna module, microphone flex. you could also replace the coax- i was suppose to be but the one i got sent was too long so i had to stick with the original one.
This is what they ebay guy sent me before i replaced the parts:
first thing to replace is the Coaxial cable (which carry's signal), check both coaxial sockets and the ports on the board it connects to
-Second (like you said) Mic Flex, although it is a tough call between the lower speaker unit and the mic flex as they are equally as likley to be at fault)
the speaker unit contains the GSM Antenna, the Mic flex simply takes the Signal to the main board from the speaker Module.
both would be Ideal unless you have time. speaker unit is relatively cheap.
finally check for any lose connections or wear to any of the Gold inside the phone where it makes a connection, using some wet and dry sandpaper rub the Gold plates Very very lightly to reveal a shinny Gold, some on the mic flex, some on the speaker unit, some on the other flex's,
and finally tighten all screws properly, often the screws can work their way out, pulling the connections away from each other.
I would suggest check the connection and wear to the gold as mentioned if u dont want to replace the parts. I found that the coax on mine has been disconnected on one end so i fixed this but it didnt help hence i ended up replacing the parts.
Service was spotty for me too.. I would have LTE and then the next second EDGE or no service at all. I eventually had to fastboot flash CyanogenOS 13 (latest stock for our device) and start over but it fixed my problem. I have not had a problem since.

I am not sure how many of you faced poor wifi reception on your HTC One S.
I had very poor reception right from day one. Tried various Stock ROMs, CM10, AOKP, CM10.1 etc.
Searching on google didnt help and all I could get was issues related radio (luckily I never had issues with Cellphone signals) and
some issues were related to Wifi on JB.
I came to the conclusion that my issue was only specific to my hardware.
Wifi signal reception was just one point around 80db or so.
There was no warranty on my phone since it was used T-Mobile purchased in India.
When I almost lost the hope, one fine day googling landed me on a similar issue with our big brother htc one x.
Here is the thread - http://forum.xda-developers.com/showthread.php?t=1688538
When I did the squeeze test on my one s, I could notice improvement in reception. I was so glad to nail down the problem area.
I didnt want to solder my HOS, instead took three threads of copper (from Electric wire) and threaded them together (like "U" as shown in picture)
Placed them at the point of contact (shown as "1" in the picture) so as to make good contact with the back cover (shown as "2")
Just put the cover back, and my wifi reception is awesome now!!!!!!!!!!!!!!!

thx it worked

Hi
In case you still have you HOS can please make a photo of your 'repair' (meaning the wire placed on the contacts)?
I tried what you said and it didn't work, maybe I'm doing something wrong.
Thanks a lot
OK, this is the only thread on the whole internet that make sense ..tried the hardware fix, soldered the U shaped wire on both ends of antenna metal in phone... didnt work...
trying something else--
is that your IMEI?
No.. The imei is fine and 3g is working great.. It seems some problem with WiFi partition or radio... I will try flashing both AMS confirm
Sent from my GT-I9100 using xda app-developers app
THANKS!!!
I tried everything on this thread: androidcentral dot com about "htc-one-wifi-problem-connecting" (google it - this forum won't let me post a link)
and then some...
I stripped some 20 gauge speaker wire and made the U shape. No soldier either. Works great. Thought I might have to tape the cover on since it popped off a couple times the first couple days, but it's seating fine, now.
THANKS!!!
Use WiFi Analyzer (free app) to check your signal with the squeeze test to avoid what happened to munnibhai (and the thread above might be useful if it isn't a hardware issue).
Worked for me as well. More of a mini-pancake shape of fine copper wires worked best for me.

I don't have the back of my phone anymore. I needed a new phone and when I got it it was missing the back to the top. Is there any other way to boost the wifi signal? I literally have to sit in front of the router to catch a signal it is extremely frustrating. Any suggestions would be appreciated. Thanks!
Hi,
yesterday my brand new Photon Q arrived, which - after doing the SIM mod - hopefully will replace my Sony Xperia Pro.
While playing around with the Photon there was some thing that disappointed me a lot:
The sensitivity of WLAN is very poor. I own 6 android devices with WLAN, and the Photon has the poorest WLAN sensitivity of all.
Using it about 10 m away from my router, through a thin wall of bricks, it tells me connection rates of about 2 MBit only (varies from 1 - 5 MBit).
My Xperia Pro shows - at the same place - connection rates from 60 to 65 MBit!
What are your expierences with WLAN on your Photon Q devices - compared to other devices you own?
Thank you.
P.S.: 2 m away from the router the speed is 60-65 MBit too, so maybe I have an issue with the antenna of the photon Q?
Hi.
Although this is pretty old, I feel like answering to it, since there never has been any answer.
What was it, that caused your poor WLAN? I guess, the guys who do the SIM mod, when they cut the small gap the inner cover where you insert the SIM later, they sometimes damage the antenna in that spot, which may be the WLAN antenna. What do you think?
I have a SIM-modded PQ, but no problems with wi-fi.When I disaśembled PQ I haven't seen anything antenna-like (wires, fractal mazes) on the motherboard...
The back piece of the phone that holds the speaker and camera flash also contains the antennas. On the bottom there is a piece of black tape that I'm pretty sure covers one. Maybe this piece was damaged where an antenna is located?

That's correct. It holds all sorts of antennas, and on the back of the battery there must be the NFC antenna, right?
The seller, who modded the phone now told me, that at the bottm, where he made the SIM slot, there is the GSM antenna, not the WLAN one. So, today I'll get to open it and have a look, what else looks disordered. Maybe some plug on the mainboard or some of the antenna contact is bad. And just in case - I have one more cover from another PQ.
But if all this doesn't help - I'm grateful for more ideas
Yes, on the back of battery that's NFC antenna. Dismounting PQ is quite easy, but you have to have a T5 torx screwdriver.
I know how to unscrew the cover and even the mainboard of the PQ and I have precise tools.
Having done so and having replaced the cover with the slightly damaged antenna by another one where everything is intact - I experience the same weak WLAN It says 1 MBit/s in 2m distance or up to 20 MBit/s, when I am 10cm next to the access point. What else can be wrong or damaged?
If the cover is ok, maybe connectors to PCB are dirty/damaged (but you've probably already checked it). And how about another router? Maybe the one you're using is damaged or "doesn't like" PQ?
Thanks for the ideas, but from what I can see, they look good and clean and bent the right way to make safe contact And yes I tries other access points. I tried with my Droid4 providing a hotspot, my tablet, at my family's house, my girlfriend's, at work, at home... It's the same everywhere: very close or up to 3 meters, no obstacles, I have signal, but 1 or 6 MBit/s only, Further away or a door in between it's gone.
Can Android (CM 12.1 / 5.1.1) cause this, or must there be a hardware issue? How likely is it that these kind of problems are caused by a broken WLAN chip rather than an antenna problem?
I bought it in this condition from a guy who modded it (SIM mod)

Flash stock if you'd like to rule out issues with CM - although I doubt it, definitely sounds like a hardware issue.
I returned the phone to the seller, it was definitely something wrong with the hardware. I ordered a fully working board from another seller, since I still had a damaged Photon Q anyway, SIM modded it myselt and got everything working now, incl. GSM and WLAN. Thanks here.
Hello,
Firstly I'm looking for a comment from an expert who has taken Nexus5s apart before. Also I'm beyond the point of returning the phone as this fault developed after replacing a screen and ribbon cable (after I smashed my phone badly). Any help or advice would be great.
So since screen and USB flex replacement on my D821 i notice that my phone signal will connect with full bars, then drop completely, I can also only get 2g where i was able to get higher. The same sim works fine in my nokia. The Wifi Signal is fine and gps works ok but the 'no service' thing makes my phone unusable. I have tried making sure all contacts are clean and even replaced the loudspeaker unit and the black antenna cable but to no avail.
Can someone put up a picture of exactly the components that are involved in the phone signal / 3g setup? Is it possible something could have been damaged on the mainboard to cause this? I can search for networks, connect (sometimes) then it will just cut out.
I tried google for days but cant find a schematic. Basically im trying to determine if there are any other parts i should try exchanging before giving up. It makes no difference how i hold (or dont hold) the phone.
Thanks
Hi everyone,
I have recently cracked my screen and replaced it myself using youtube tutorials. I have (somehow) completed the task although I had many problems with the two side cables (black and white antenna cables, I hope you know what I mean as I don't know their proper names). Specifically, I wasn't able to slide them down the channels intended for that and at the same time I wasn't able to connect them properly in the jacks were they need to be plugged in. I thought I have somehow did it but it seems I did not do it properly as I do have frequent ups and downs with the network signal, I lose it constantly in places where I used to have full network signal and I can't reach LTE at all, there's no connection at all when switched to LTE. There's signal only when 3G is ticked in settings and internet signal remains to E, rarely if ever moves to H.
At the same time, Wi-Fi is good although I feel it worked better previously, but that can only be my imagination working.
So, I think it has something to do with those cables, as those were my main issue during reassembly. Is there any advice anyone can give me. They don't seem broken, but I can't fit them in the channels and in the jacks properly. Would it work if I put something like a sticky paper in the channels to hold the cables down. Also, is there any trick for connecting them in the jacks or I just need to be precise?
Or, is the problem something completely different?
Any advice would be much appreciated as my phone is rather new and I absolutely love it.
Thanks in advance
Those mini-coaxial sockets can be a bit harder to push in at times - just get a pair of good quality tweezers , get a good grip on the connector and push it down with some other tool. I can guarantee it is going to go in . If they don't make good contact you are either going to get intermitent network , or a very week network signal .
At some point in time - I can't tell exactly when - after replacing the earpiece speaker of my N5 and updating to the latest Lineage OS version 3G connectivity stopped working.
4G works fine, but if there's no 4G reception or the phone is forced into 3G mode using the settings it drops down all the way to 2G, although other phones on the same network have flawless 3G reception.
I have reflashed the radio and both the newest and oldest factory images available from Google and also tried cleaning the contact surfaces of the antennas in the back cover and I've also bent up the contact springs a little to ensure more contact pressure, but nothing has helped.
Since 4G coverage is far from 100% in my area this effectively limits the phone to 2G most of the time which makes it pretty useless.
Does anyone have an idea what could cause this problem?
Thanks
Open the smartphone again, check connection on both ends of black and grey antenna cable.

The black cable's connector on the upper, larger board was loose - most likely due to it being so close to the edge of the phone and me not paying attention when prying the back cover open.
I reconnected it and now 3G works again :victory:
Thank you
