Intel AX211 Slow and Unstable

Hi,

 

Few weeks back I got Samsung Galaxy Book 4 Pro 16 inch variant with following config:

 

Intel(R) Core(TM) Ultra 5 125H, 16 GB Ram, windows 11

Intel(R) Wi-Fi 6E AX211 160MHz with driver version 23.40.0.4 and all other windows & bios updates has been installed.

 

I have a 200 Mbps connection and my router config is:

 

Device: Huawei HG8145V EchoLife HG8145V GPON Terminal (CLASS B+)
Hardware Version: 13A9.A
Software Version: V3R017C10S200

 

Recently when I was playing a game, I experienced some lag which then made me do a speed test so that I can understand where's the issue. To my surprise, its only this laptop which is experiencing slow speed and high jitter.  I did speed test at same place from my s22 Ultra phone and also 2013 iMac; both gave satisfactory results. If I remember correctly, this was not the case when I did fresh boot on day 1. 

 

Wifi Details:

 

SSID: AIR 5GHZ
Protocol: Wi-Fi 5 (802.11ac)
Security type: WPA2-Personal
Network band: 5 GHz
Network channel: 36
Link speed (Receive/Transmit): 520/520 (Mbps)

 

Here are speed test photos on my laptop and mobile (s22 ultra)...

My issue is similar to something what discussed here :

I have uninstalled/installed and played with driver settings several times but that did not fix the problem.
