General Help

I have a dual boot configuration and connection is very slow compared with windows.
Below is my configuration:

Some Questions:

  • Are Secure Boot and Fast Boot in BIOS disabled?
  • Is Fast Start-Up in Windows disabled?
  • Did You checked the ''Additional Drivers'' Tab in Software & Updates if there is a Driver offered?
  • Does Your System run in Wayland or X11? You can check that with the Terminal Command echo $XDG_SESSION_TYPE

I see, You are in Kernel 7.0. Please try it with going back to the older 6.17 Kernel and check if it works better. To do that choose on the GRUB Menu on Startup ''Advanced Options'' and choose there the Option with the 6.17 Kernel (without Recovery Mode).

Yes, I seem to remember that a lot of network libraries were removed with the update to 7.0 and seem to also remember that A.I. was used for the Networking elements for kernel 7.0!

Secure Boot and fast Boot is disabled.
Fast startup disabled.
Only nvidea drivers for video card are offered.
Wayland.

I chose 6.17 and still the wifi is slow.

I would suggest to switch to X11/Xorg to check if it behaves different.

To switch, go to the Login Screen. click there on Your Profile so that the Password Feild appears. When it is appeared, You should see in the botton right Corner a Gear Icon. Click on it and choose the Option ''Zorin Desktop on Xorg'' and then log in.

I'm assuming your internet is slow when using Wifi. Could you check your region?
Terminal:

iw reg get

It should say something related to your region. For me it's DE although I'm situated in the Netherlands. If it's global or something then it will slow down your wifi speed.
If not correct you can change it with:

sudo iw reg set US

Or whatever country you're living.

To make it permanent:

sudo gedit /etc/default/crda

It should contain "REGDOMAIN=US".

It did help me to solve (a part of) my wifi speed problems.

It behaves the same under X11/Xorg.

8

The region was already set to US

You can try to reload the kernel modules

sudo modprobe -r iwlwifi

sudo modprobe iwlwifi

Also test if it helps to disable bluetooth to see if there are interferences between bluetooth and wifi.

Then, I would suggest to try it with switching back to the older 6.17 Kernel to see if it works better. To do that, choose on the GRUB Menu ''Advanced Options'' and there the Option with the 6.17 Kernel (without Recovery Mode).

You can also try to disable Power management for your wifi card.
Terminal:

sudo gedit /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Set wifi.powersave = 2 (3 = On)
Maybe that will help.
