Hardware Support

Hi guys, i just switched from linux mint because my internal microphone never worked. I had the same issue here but a zorin os forum had my same issue and i fixed it after 3 days trying to fix it in linux mint. But in zorin os (also linux mint) the wifi is really slow and its hard to play games. please help. This is my internet card: Ice Lake-LP PCH CNVi WiFi
also im using a laptop this is the name: X509JA (intel i5-1035g1)
thank you

hi i also tested the wifi speed this is it https://imgur.com/a/t6QjJPR

i also tried it on my phone (im not close to the modem) and i got 119 download and 51 for upload. it looks like the problem is just the download

Have you yet disabled powersave on the Wifi?

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

user arrow keys to navigate. Change the value to 2 so it looks like:
wifi.powersave = 2

Tap ctl+o to overwrite, enter key to save current configuration, then ctl+x to exit the editor.

Cycle a full reboot to test.

I also recommend using 2.4GHz instead of 5 if your regional towers are 2.4, since having it set to 5GHz can cause conflict on signal transfer.

it didnt change much just 5/10 more mbps on download which is not that bad but i wanted it more faster because in total i got 22 for download. on my phone is almost 5 times that.

Have you tested your distance from router or if any interference is between the computer and router?

im a bit far from the router because my laptop is upstairs and the router is downstairs. but in the same position my phone gets a better result so its not the distance. also when i was on windows 11 i always got 100 or more fore download

Have you tried rebooting your router?

If Windows is working at same distance and position, I agree that this is a driver communication issue, not router position issue.
Can you try the pcie_aspm=off grub parameter? (NOTE: you would be changing to using the pcie_aspm=off parameter, NOT the nomodeset parameter):

Websearch using "Ice Lake-LP PCH CNVi WiFi Ubuntu 24.04" throws up several hits, but no solutions I have seen.

I wonder if a later linux kernel may help.

After the word splash
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Change to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off"
Then tap ctl+o, enter key, then ctl+x
Run

sudo update-grub

You can reverse the process and revert it to just
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Then tap ctl+o, enter key, then ctl+x
Run

sudo update-grub

Next, you can try Zab's suggestion of no higher than 6.3 kernel.

sorry im new to this how do you change the version of the kernel and also are older kernel safe to use and stable?

17

Yes, if you are not on cutting edge hardware. Newer hardware might need what is introduced in later kernels.

FYI. The last kernel I had for Z16.3 Core was 5.15.0-136, which is in the range 5.7 to 6.3.

Well you could always get an inexpensive (linux compatible) USB wifi adapter as alternative.
