[Q] A different wifi problem - Galaxy S III Q&A, Help & Troubleshooting

Hello, people!
I have the following problem: my galaxy s3 recognizes the wifi networks around. Sometimes, when the wifi is full of signal, my phone can connect. In this case, if I turn around or lost one of the signal bars, the phone still connected, but I can't open any website, or use the whatsapp app.
However, in general, I can't connect in any wifi network. What can it be? I've tested a lot of ROMs, kernels, but I still have no results.
Thanks!

You have a hardware fault, possibly the aerial module.

So I have to change the wifi board?

as far as i know the wifi module is part of the main motherboard, so if thats broken than a whole motherboard or phone replacement would have to be done
however it could be a broken aerial or a loose aerial cable ( just because it will identify a full signal doesn't necessarily mean the signal is strong enough to support data flow).
if you can get your hands on an aerial and are brave enough to open up your phone, then its worth the shot, otherwise just take it to a service center and theyll find out whats wrong with it

[Q] Wifi connection problems

I'm able to connect to any wifi network but only if I'm three or four meters away from the router, if I'm in another room or whatever I can't. With my old smartphone I could acces to my wifi network from my bedroom and now I can't with the razr. Do you know if its a hardware problem with the wifi receptor or if its something that has to do with the software? Please help
Wifi could definitely work better on the razr. The signal was decent on FTS rom (ICS) and now on liquidsmooth 2.9 and 4.2.2 it's even worse...
^ This, it seems wifi has been getting worse as the updates come, its not as drastic as a few meters away from the router but i now lose signal in places that were pretty solid before. If you really have to be a few meters away i'd take that baby apart and check out whats going on in there :silly:
If the wifi signal is weak, maybe the antenna has moved.
Can you unmount the phone or did it already??
You need to check all the border metal conections.
The wifi antenna, is marked in the attached picture.
I hope you can fix it.

[Q] Weak wifi reception

Hey guys,
So I've been having some problems with my wifi reception on my Galaxy S4. I'm not entirely sure as to what the problem is, but hopefully you guys can help me.
Unless I am very close to my router (~10 ft.), my wifi reception is marginal. However, sometimes, when I am far away from my router, and I put pressure on the back of my phone near the power button, the wifi signal instantly boosts up again. It is for this reason that I originally thought that the problem was with the wifi antenna. I changed the back housing which contains the wifi antenna, but to no avail. I have done everything you would find online such as keeping wifi on when sleeping, etc.
Please help me out. I really need my wifi.
Thanks.

Help Fixing GPS - Timmy E86 (mediatek)

My 2nd post with this accound but ive been a member for qutie a while but was inactive for a few years and cant recover my account.
Anyhow i bought a Timmy E86 . Its pretty cheap but pretty good apart from the GPS
It has the mediatek 6582 chip.
Ive been through just about every mediatek gps fix.

When i got the phone GPS signal was non existant. even after using many different gps fix apps.
I then discoverd that without the cover on and the antenna peeled back i managed to get signal, put cover back on and signal goes. So the cover is blocking signal.
I extended the antenna with a make shift foil antenna, which improved the signal slightly and allowed signal with the cover on. Great thinking its fixed, however navigation was terrible, loosing signal and the heading facing wrong way.
Then it lost all signal again after a restart and woukldnt get signal again randomly until smoe while later. Satilites show but zero signal.
The antenna is rubbish on this phone,
I know this is probably the main source of the problem, i plan on remove the case cleaning the contacts and installing a better antenna, either made of copper tape or perhaps something else.
But im pretty sure theres something else wrong deeper down in the software.
I done some further testing yesterday managed to get gps signal and 3d fix. Since i was being a passanger rather than driver i could see what was gong on. as soon as we started moving the satilite signals would drop to 0.....
ni thoughts?

Finally tracked the issue down to really poor GPS antenna.
Remoived it, replaced it with bare copper wire from a power cord , made sure it was well twisted so all the strands were together and neat.
Used the end of the GPS antanna that contacted the board and soldered it to the the pad of the old gps antanne end, so that when the case went back in it contacted the board pin.
Success. GPS lock indoors at a window and still picking up satilites away from window but not enough for lock.
Until i screwed everything back together and tried to put the back on, the cable was too thick and it pushed the board. GPS signal no longer works.
Even tried replacing with thinner cable and solering direct to board but same result. satalites in view but no signal, not even outside now.
Guess ive either burned out the gps somewhere or something on the board got damaged from the cable pushing on it. Even removed the SMD contact pin and soldered wire directly onto the board. Still nothing

Given up on getting this to work. either ive broken something in the gps or the phones setup has went iffy.
Satilites are apparently in view but dont ever get a signal from any, all 12 satalites sit there with zero signal even outdoors.
The easy solution?
Use my old phone that can get a lock inside next to a window as a bluetooth GPS reciever. Using Bluetooth GPS output, and then the bluetooth GPS app on my timmy phone.
Result? Perfect navigation using Tom Tom GO. This is actually a much better solution since the phones GPS is off its using much less power. My old phone is an alcatel one touch which is pretty good for battery even with gps on plus with the screen off doesnt need charged while using it for hours as gps+bluetooth.
Another advantage, i can have a gps app open on old phone for speed and have a GPS speedometer running while navagation running on my larger timmy e86.
My recomendation is just get a bluetooth GPS reciever if your gps sucks.

HTC WiFi issues

Here's the issue I have a HTC Desire 526. It's prepaid through Verizon Wireless I'm having severe Wi-Fi issues. In order for me to connect to my router I have to place my phone within an inch then use WPS to connect. Once I'm connected I cannot walk more than two feet before it disconnects. Once it disconnects it says either disabled or null under the SSID. While I'm connected I cannot use apps that that use high bandwidth like Twitch. While I'm connected to the internet I hold 5 bars never more, never less. I have attempted to clean the Wi-Fi antenna if I correctly located what appeared to be the Wi-Fi antennaa according to pictures on Google Images. As well as the GPS antenna I also unplugged and plugged all of the what appears to be brass or gold plated terminal thing wires back in. I have 3G and what appears to be three signal bars but it usually takes 2 to 3 minutes after the phone starts to turn on. I've never had any issues like this with any other device or router or Internet or anything. I may have while unscrewing the void screw possibly cracked the board somewhere that's what I'm thinking. I also broke whatever the microphone looking thing was attached to the screw, does anybody know what that is?
Also the Wi-Fi turns on and off normally it also scans other ssids which I know are fairly far away in The Neighbourhood so I don't think it's a Wi-Fi antenna issue.

LG G5 network problems after attempting GPS fix - only 4G/3G - no 2G signal

As the title goes I tried to make a GPS fix buy adding a little thin plastic under the pins showed in the video tutorial I used but after assembling back the phone noticed that I cannot connect to 2G anymore. I switch to 4G and 3G with full coverage but when I try to went back on 2G the network signal drops and phone says "Emergency calls only". I opened it again and removed the plastic board and switched it on and got slmost perfect 2G coverage but my microphone stopped working - nobody was able to hear me speaking so I opened it again and added a little card board piece on the place and now I have good mic with good 4G/3G signal but again with no 2G signal again. Can somebody tell me what I'm doing wrong ? Also where are the exact places of the 2G/3G/4G/GPS antenas ? I travel a lot on places with low 4G and even low 3G coverage so I really need the 2G mode again. Please help me fix it as it was before. I need 2G more than GPS so if somebody tell me how to reverse this would really appreciate it, thank you !

Ima follow this one closely. Mine has the very same issues ive bassicly asked the same thing
Mine does it one all three. Rarely picks up 2g gsm network gets crappy 3g and lte. I use lte discovery to verify all this. Now i have noticed that if i pinch the chin or hold the phone like laying in bed only by the chin i get killer signal and even pick up 2g at the same time as lte.
I watched other devices all get band 5 lte and gsm at the same time.
I cant find any confirmation on where the antennes are even located in this device.
Today I noticed that my sim tray stays slightly out of the phone body so I tried to push it in and it wasn't going any furder as before. So I though there must be something in the tray preventing it to push in till the end and I used a magnifyer to see inside and noticed a small plastic that seemed from the same material of the pick I used to open the phone so I got it out and now the sim tray is closing nice again and now I'm able to connect to 2G but still the reception is not good as it was and it drops from time to time... Still this is an advance in the right direction. I think I had broken or bent or moved something slightly off place from these several interventions so I'm f****d up.
Please guys don't try to make any gps fixes because you will do more harm than good ! That is my advice !
If still somebody can help me, please write ! Thank you !

Please share where the f**k is the 2g/3g/4g cellular antennas PLEASE !!!!
Nobody here is engineer at LG. And nobody here has any real solution for GPS / 2G / 3G fix. Looks like GPS breaks again even after sending it to repair. This LG G5 has been the crappiest phone I ever bought. I'll be buying a G6 soon.

The 3pins in the video are for the Volume buttons. The REAL GPS antenna are the ones next to the headphone jack.
So far I experimented that the cell antennas lies at the top of the phone since covering the top-middle section of the phone Cell signal drops.
Maybe the plastic shim you put in is too thick that it's interfere with other internal components, like the black RF antenna ribbon that runs across the top section of the G5. See if removing the plastic piece resolves the problem
Hi guys,
Just want to let you know that I gave the phone to a service and they found out that I broke some of the pins even without noticing. That is why this problem occured! They were able to replace them so now my phone is live and kicking again with full network coverage on all bands (2g,3g,4g). So happy with it ! So go ahead and bring your phones to a repair service center and make sure it will be a good one! First I went to affiliate LG service and they told me that most of the things are unrepairable and will have to change the whole motherboard which costs as a new phone so I lost any hope fixing it but later a friend of mine recommended another service where the guy told me he will inspect all the parts of the phone and will call me if he finds anything suspicious or broken. So I left the phone and after 2 days he called back and told me that 4 pins were broken and 2 more damaged and bent badly. He also told me he thinks that if we change them the problem should be solved so I agreed and he did fantastic work on the phone and now works as new !
So don't be disappointed and find a good service where they can try to help you. Also when you are doing some mods to your phones please be very careful!! I confess that I wasn't careful while doing the mod - I was at work and even didn't had the necessary tools for the task, also the colleagues were around and distracting me so I wasn't able to focus entirely on the task and did more harm than good! Good luck !
Thread may be closed, problem solved !
