I9505 very weak wifi reception - Galaxy S 4 Q&A, Help & Troubleshooting

My Galaxy S4 LTE aka I9505, running 4.4.2 stock rom, has a very weak wifi reception. I have to go very near, like meters away from the router, in order to get signals. While other phones and tablets can even detect and connect inside the room, which is second floor. Tried all sorts of wifi fix apps, flashed the relevant modem and flashed many different 4.4.2 official stock roms but no luck at all. Also, changing the router settings e.g. SSID name, WPA/WPA2, AES, channels, ghz, doesn't seem working also.
Baseband version: I9505XXUFNBE
The previous user told me the wifi reception only turned weak after he rooted the phone, and it might be a kernel's problem in stead of hardware. May I know is there any kernel that can solve this problem? Can someone with I9505 that has strong wifi reception show me what kernel him/her is using?
A million thanks in advance.

[Q] [SGH-I337M] [Smsung Galaxy S4 Rogers] Problem of connectivity

I have 2 Rogers's SGH I337M. The Modem have version I337MVLUAMG1.
I am in Cuba, the connection use operator ETECSA. This net uses technology
GSM of 900MHz.
I am having serious problems of connectivity. When starting, phones get
connected and they get registered to the net normally. Later they lose
the record in the net. Then he gets connected again. This happens to me
even with the indicator of signal full. Who calls me, largely receive that I am
off or out of the area of coverage. Besides when I can make a call they
do not listen to me correctly.
I have seen other S4's models that work correctly here.
I may be possible modifying the modem with someone version model?
Somebody can help me solving this subject.
Thanks...

[Q] How can I fix my note 3's signal reception?

So... my Note 3 is like new, no exterior damage at all, I've taken well care of it, but I'm having some problems with signal reception.
Using LTE/GSM/WCDMA mode (or LTE preff with CM based roms) where the phone prefers 4G signal, I have 1 or 0 bars of signal, I miss calls and texts and web browsing using data is really slow!
Using GSM/WCDMA (3G mode in CM based roms) I have like full bars but slow internet using data, I don't miss any calls or texts (at least I didn't notice it) but when I am in the train and I pass through a tunnel, the signal is lost and it never recovers, I have to remove my battery and reboot the phone to regain signal (my other phone, a Galaxy Nexus, loses signal only inside the tunnel, then in seconds it reconnects again like it should, I also have full bars everywhere and no problems with the same SIM card, I also have an LG G2 at home and LTE works very well with the same SIM on that phone, it's just Note 3 that has really poor or no reception at all).
I don't think this is normal and I don't renember having problems like this in the past, how can I fix it? Please help me since I can't find any info by browsing and everyone knows Samsung isn't cheap when it comes to fixing things with knox 0x1, and I am fine fixing it myself if I know what to do.
Do phones use different antennas for LTE and 3G/2G? Is it an antenna problem? How can I pinpoint the problem? How can I repair it?
Thanks in advance.
EDIT: forgot to mention, I've tested this on many custom roms (CM13, CM12.1, RR, N5 ports, S6 ports, Aryamod, Stock Samsung Lollipop, Stock Kitkat) the problem is the same everywhere so I think it is hardware problem.

No wifi in a brand new yd201 from Hong Kong

Hi
I'd appreciate if anyone could help me with this.
I received a new yd201 last week, and I haven't been able to connect the wifi. It doesn't detect my wifi signal even if I'm touching the router with my left hand when trying. I've tried all the tricks I could find in the internet in order to solve this: change settings, (including developer settings), hard resets... but nothing changed.
There are about 15 wifi signals I can see with any device at home, but Yotaphone only shows 1, and it's my neighbour's.
Thanks
If it is possible you have to understand difference between WiFi of your neighbor and your. It is possible changing region in the wifi advanced menu change your situation... or changing in the same menu the frequency band of WiFi.
Did you look in the extended wifi settings if the wifi frequency is set to automatic?
It could be set on 2,4 Gz or 5 Ghz.
Some Routers only have 2,4 Ghz.
You can try putting 2,4
It is possible the router of your neighbor is only 2.4
I have tried every trick there is available in internet.
It shows only 5 Ghz channels, no matter which otion is selected in the advanced settings menu. If I select 2.4 Ghz no chanel appears ever.
Wrong Radio Rom installed? (f.i. 2.3-2.4 GHz is 4G in Asia, HK-Radio-Rom installed?)
In most other countries
YD201 should work with RU-Radio
YD206 should work with CN-Radio
You are shure, that your Yotaphone is YD201? IMEI is 356...?

I'm pretty sure the RU/CN radio has nothing to do with this problem
I'm using a YD206 with RU-Radio and I can use wifi/bluetooth/2G/3G/4G all fine.

SM-N910G WiFi & Cell Signal Issue

Hey guys,
I've been using my Note 4 for a couple years and it was running smoothly before but now it started showing issue, I hope y'all can help me with these problems..
Problem 1: Dual-Band WiFi Connectivity Issue
My N910G could not connect or even find any 5GHz frequency WiFi connection(neither my home WiFi nor the others),
but it shows no issue connecting the 2.5GHz frequency. My home router is working perfectly fine and my other devices which supports 5Ghz band have no issues connecting to my home router so I don't think this is the router at fault. I've tried reset my N910G to factory setting, at the setup it miraculously connect to the 5GHz band without a problem but as soon as I turn the WiFi off or leave it after a while, it disconnected and it does not show any 5GHz after that.
Problem 2: N910G Poor Cell Signal Strength
Okay, now this is a bit tricky. Recently, I changed to a new cell company and sign up for a postpaid package with LTE data only, the sim card is new but as soon as I insert it into my N910G and reboot it. The signal strength of my phone only range from 0 to 2(which is from -80dBm and above) and rarely reaches 4 or 5(highest) but I still can connect to the 4G network, it's just the signal is very poor. At first, I thought it was the sim card at fault but I tried trying it out on another phone and it works just fine.
Can someone help me out with these two problems? Is it because of faulty hardware or software? Does flashing a new custom rom helps to solve these problems?
