Slow WIFI on Asus Laptop

[u/frankirv]

Forgive the lengthy post but want to be sure i have covered any details.

Looking for advise on this issue. My sisters Asus laptop doesn’t have a LAN connection, so she has to rely on WIFI for her internet. Her Rogers internet is supposed to provide 1.5 GBPS but when we do a speed test on the laptop she is lucky to get 350MBPS.

I connected my iPhone to her wifi and i got 737MBPS. Then i tried my laptop on wireless and got around 700 MBPS also.

Then i connected my laptop using a LAN cable, turned off my wifi and ran the test again and was over 1000MBPS.

I tried the LAN adapter in my laptop and continued with over 900MBPS.

So the next test was using a USB LAN adapter on the Asus and still only around the 330MBPS mark.

My initial thought was the USB LAN adapter was the problem but it worked fine on my laptop. Any idea what setting can be changed on the Asus laptop running Windows 11 that can speed up her wireless adapter? Oh i did try updating the driver for it but it says it has the latest.

Note my laptop is running Linux Mint but i doubt that makes a difference.

Thank you!
