[Solved] WiFi Problem

[azrobert]

Running Mate 20.1

I have a Shuttle XS35-701 with a RTL8191SE WiFi adapter.

Ookla Speedtest shows 17Mbps download and 30Mbps upload.
The download sb approximately 50Mbps.

If I remember correctly, I had an older version of Linux that ran correctly.

System Info shows rtl8192se driver. That’s 92, not 91.

I found a link suggesting rtl8192ce driver. If installed, how does the system know to use this driver?

Any suggestions on how to fix this?
Thanks

See if it's any better with power management turned off:

Code: Select all

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Reboot

I tried 3 different servers and the best was 33.21 down and 28.79 up.

The internet response has noticeably improved, so I can live with this. Am I right or wrong that it should be about 50 down. Is there anything else I can try? I won’t be using this compute much, so don’t spend a lot of time researching this.

Thank You!!!!!!!!!!!!!!

I don't know if it will help any, but you can try reloading the driver:

Code: Select all

 sudo modprobe -r rtl8192se && sudo modprobe rtl8192se && sudo systemctl restart network-manager.service 

[azrobert]

That command returned the low down numbers, so it looks like it removed the change from the 1st command. I re-entered the 1st command and re-booted. I'm now getting around 30 down again. I'm happy with this and will mark this topic as solved.

Thank you again!

Ok, unless someone else has an idea, that's the best it will be.
