[Q] Strange wifi/wireless problem - Desire Q&A, Help & Troubleshooting

Hi everyone,
My g7 is having problem with wifi (and bluetooth, but I mostly use wifi). The issue is the wifi signal strength is extremely low. Only when I put the phone just next to the wifi AP, it will get a strength of 3-4 (not full) slots. In most cases if you walk away from the AP for about 5 meters, the strength will go down to almost nothing and becomes very unstable.
bluetooth? even in discoverable mode, it is not discoverable.
I think it might be a problem of some kind of antenna inside it. how could I check? i have disassembled it.
I noticed when I remove the chin of it, the phone signal will go to zero (the GSM signal) and I know there is an antenna in it. Isn't the wifi sharing antenna with the mobile network?
My radio is latest according to the forum. Trying cm7.0.3 and oxygen 2.2.1, both same issues.

hardware defect
working fine for me on both and no bug have been reported on both roms.
must be your hardware defect, sorry. still in warranty ?

Random Reception problems

My Trinity has decided it's had enough of working and is doing some crazy stuff. Firstly if you have the phone in Automatic registration it never gets signal but will say G or 3G etc. At this point I cannot make or receive calls or texts. The only way I have managed to get it to work is by turning Auto to Manual and selecting the network..yet sometimes this doesnt work, it will show reception but calls and texts still dont work, Data works tho!!
The only way I can get a working phone is selecting GSM from the network type instead of Auto. Obviously it sounds like a 3G/UMTS problem with the phone, Sim works fine in other phones. Have tried reflashing ROM and Radio.
ANy Ideas
are you sure you have good 3G coverage in your area?
I would phone your operator.
I had a similar problem on Vodafone only when set to auto. The phone tries to pick up the 3G weak signal and so it's always droppin off and on.
The guy at Voda suggested that my phone was paired to a 3G base station several KM away, when it could have used the GSM station a few 100 metres away.
A plus of using GSM is battery life lasts much longer!
Of course there could be a hardware fault which would be unfortunate.

I assume that you've configured your phone to your operator and that you've tried different radio ROMS to ensure optimal "fit" between your specific PDA and network operator. If you haven't and none of sickboy555's suggestions work, maybe you should check these two alternatives out as well?
Cheers!

Well the problem initially started at random, did actually do anything, also I have tried about 4 different ROMS now and all have the same problem. I'm on
In terms of reception I have full 3G signal (4 bars according to the screen) as I am just outside the centre of the city yet nothing comes through but data. tis V strange. I may retry 3G when I'm somewhere else just in case its down to the local Cell.
I've decided to bite the bullet and just disabled 3G most of the time, if I need faster data I'll turn it on for that until I can upgrade to the TyTN 2. mmmmmm

Crappy wifi?

I'm running Damage Control 3.2.3 since I got the Evo about a month ago so I don't have too much time running the stock ROM.
I've noticed the wifi signal sucks! I can be using the wifi sitting on the couch a few from the router and my signal dropouts out every so often. I'm also running the latest radio (2.05.00.06.10).
Anyone have wifi issues?
Sent from my PC36100 using XDA App
Mine isn't THAT bad. But I have noticed the signal seems abnormally lower than other devices. And there are places where I can't even see a wifi signal that other devices can see and connect to.
Anyone have any insight as to why our Evo's arent good with Wifi Reception ?
problems with wifi, reset router.
I had problems with my wifi signal. thought that it was because of my flashing back and worth from rom to rom. Finally, decided to reset my router and voila! signal problems were gone.
this is totally non-specific to a router.
My laptop had full strength. My evo has one bar. Same thing at home, other people's homes, hot spots, etc. My friends iPhone picks up wifi signals i can't even see. It's pretty annoying. Probably just an inferior antenna inside the phone.

[Q] What does the antenna do?

I have a HTC with the dodgey wifi antenna in the back. I want to know if this faulty antenna will effect the phone in any other way except for making it unable to connect to wifi.
I'm not sure whether to send it in for repair as I will be without a phone for a long time
AFAIK, WiFi antenna is (as name says) WiFi antenna. Your 2G/3G has separate antennas. So, mostly WiFi is affected. Of course, if WiFi antenna is dodgy, then there could be interference from WiFi to your cellular area that can cause poor reception, but I cant be sure. Why dont you take it to the service center? after all you paid a fair amount of money to buy this device!
This was an issue that HTC has recognised officially, so you can get it fixed or in some cases I've heard a complete replacement unit. AFAIK, like nandann mentioned, it should only affect your WiFi connection, other functions should fine.

New Problem GPS

Hi guys.
I have a strange problem with the gps.
I've been with lg4 for 1 year and had no problems, this week strangely I started to fail the gps, it connects sporadically, I checked the GPS fix and GPS status toolbar, and it does not work.
Doing tests I discovered that when disconnecting the data network the gps works great in a second it locates me. I just turn on the 3g data network the gps reception is lost. If I leave only 2g network and gps works perfect the gps the bad thing is that the data network is very slow.
Conclusion:
1. It is not a problem with the GPS of the phone because it receives the signal from the satellites.
2. When disconnecting the data network works perfect
3. When connecting the data network but only in 2g works perfect
4. When entering the 3g data network, the GPS fails.
Any suggestions?
I forgot that I am not a leading user to pay attention to my question
I have similar problem with G4 from the beginig. But I have not a solution. Quick connect to GPS but sporadically lost signal
for the one that interests you.
I had this same problem in an HTC m10, I thought it was a defect of the smartphone I sold it and I was with a huawei y5 ii and it always worked perfect, it was not very efficient but the GPS always worked for me. After a few months I decided to buy LG G4 for the low price and good benefits. After a few months and after overheating the GPS began to fail as described above and as did the HTC, I also remember that the HTC overheated bastabte and as it was metal felt even more.
The case is that strangely presented the same failure, after consulting a thousand times online and seeing that there was no answer and that the XDA teachers did not pay attention to my question. I took him to an LG service center and they told me the following:
1. When a metal is heated, it expands and contracts with the temperature ... that is not new.
2. When this happens on a smartphone the connections of the antennas that are usually like sheets of springs, stop making good contact with the phone's cover. This is because they are pressed and remain flat without making contact with the antenna.
3. This causes that it does not detect well the networks ... well it is data network, cellular network or as it is the case the signals GPS.
4. The smartphone should be released and verify that all connections are in good condition.
5. In my case, the technician lifted all connection patices so that they made a stronger contact.
with this not only fix the GPS but the cell signal is always at maximum.:laugh::laugh:
If I had known this I would not have sold the HTC
I tried the smartphone all day yesterday with UBER and the GPS function worked perfectly, please close the issue RESOLVED

Loosing signal/network

Phone looses signal(mostly network) on different areas where there is signal. I read that this could be caused by updates, so I did a fresh install of latest A10 version (it did fix wifi problems), it got better, but still is not acceptable for daily use. Then I installed latest oreo rom, again it got a little bit better, but still not good enough. Afterwards I discovered that if signal has gotten weak setting preferred network type from 4G to 3G or vice versa gets connectivity back instantly. Also for some reason the sim slots are swapped in settings and slot 2 doesn't get signal at all(only saw this when I got oreo, can't say if this was present on A10).
Is this a software or a hardware problem? I got this phone in a pawnshop(had to get a cheap phone ASAP but couldn't afford a new one at the moment) a few days ago and if it has a hardware problem then I still have time to return it, otherwise I would like to fix it and keep it.
Seems like I have found a workaround, I installed latest POSP custom rom and set 4G/3G only in network settings, it still can loose network signal for a few seconds in a low signal area, but a few seconds isn't causing problems. Still have to do some testing but I'm inclined to think that this is a hardware failure, but if my workaround does the job I'm fine with it till I can afford to buy a new phone.
