Galaxy S3 I9301 - Low WiFi Signal Even After Factory Reset - Galaxy S III Q&A, Help & Troubleshooting

i9300 - Low WiFi signal
Hi guys,..
I need a help. My phone has very low WiFi signal. I thought it could be ROM's problem so i flashed stock ROM back > but it hasn't helped.
I checked wifi antena, i tried to put it out and run phone without that, but phone still could connect to WiFi without antenna.
I have S3 NEO (i9301) motherboard, but there is no antena like in S3. ( i wanted to change antena).
Do you have some advice for me?
Thank you a lot:crying:

[Q] problem with GSM network

i notice that my phone have problem of losing connections (phone signal) quite often which causes the phone cant make or receive call. i usually go outstations and everytime when i travel i have this problem. i thought it was the problem from the android 1.6 but after updating to android 2.1 through the SE website the problem is still there. recently i end up with the conclusion that my phone have problem with GSM signal, whenever i go to outstation where there is no 3g/WCDMA in the area but suppose to have the GSM signal i got this problem. please bear in mind that i have change and tried the setting for WCDMA ONLY,GSM ONLY & WCDMA/GSM PREFERED but the problem still persist, and please bear in mind i have tested with my other phone and it works fine at those places. please advise if this is the problem of the phone itself or just the setting of my phone.

[Q] galaxy s2 keeps losing wifi connection

Hi,
We have 2 galaxy s2's in the house one works fine but the other (luckily for me its my wifes) keeps disconnecting from the home wifi, it even requires the password to be re-entered each time. I have cross referenced settings on the 2 handsets but can find no differences.

SAMSUNG Galaxy S3 I9300 Drop Signal Issue

Hi. My Galaxy S3 i9300 drops network connection from time to time for no reason. I have a full coverage in the city, all the signal bars are full, however it drops the signal sometimes and reconnects again. That's very annoying while talking on the phone. What I tried so far:
Clear cache
Hard reset
Changed to another custom stock rom
Installed another kernel and modem driver
All these makes me think that it's a hardware issue. Anyone who knows what it might be and how can I fix it? I have a hot air gun and I am able to replace parts if one knows which part might be faulty on the motherboard. Thanks!
*#*#4636#*#* and change to gsm only (mobile network will not work, changes work untill reboot). Use that if johnny_GSR post dont work for you.

4G connection problems. Help!

Good afternoon,
I have a galaxy s6 925i,
I'm having problems on the network,
Performing some tests and realized that the problem is with the cell phone.
Before my phone took the 4G network normally, after I switched to the NN4 ROM I realized that my 4G signal did not work anymore. I thought it was cell phone coverage issues.
I changed operator and continued with the same problem.
I changed the ROM, did the wipes and nothing.
I put the original ROM, I installed the MODEM file and CSC and it did not work.
My wife owns a Galaxy S7 and I use my chip normally in 4G.
At the moment I am with the ZTO ROM my signal is very intermittent and I do not know what to do.
If anyone can help me.
I thank you all.
