My internet is slow on Linux but fast on Windows

This is what is shows

odlund · June 15, 2023, 6:14am

Hey, great suggestions. Unfortunately, this didn’t work. I created a file ```
/etc/modprobe.d/iwlwifi.conf

odlund · June 15, 2023, 6:16am

Hey, it’s the wifi. I don’t have an ethernet cable connected. And with the same internet configuration on Windows, i am averaging 230mb/s downloads and 200ish uploads.

For better readability/visibility, please post the terminal output as text and not screenshots.
It would make it easier for the helpers to copy and quote on the output and also it would be searchable by forum’s search function.

Copy, paste, highlight and pres Ctrl-E to format.

@odlund :
What does the journal say? Which firmware is loaded etc.

Please share the output of the command “journalctl -b | grep -E "iwd|iwlwifi”

Also please share output of
ifconfig
and
netstat -r

@odlund

Try adding this also to the

/etc/modprobe.d/iwlwifi.conf

Add

11n_disable=8

Edit: You could also try disable bluetooth coexist by also adding.

iwlwifi bt_coex_active=0

Edit: You could also try the latest firmware.

@odlund
Do you actually have an AX capable WiFi 6 router? Otherwise it will be running on the AC standard or whatever your router supports.

Hey, this is what the command yields:

Hey, thank you for your support.
yes, my router supports wifi 6.

odlund · June 15, 2023, 5:00pm

This seems to be the latest firmware:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/
how would i go about installing it?

ricklinux · June 15, 2023, 6:26pm

If you look at the information that intel provides for that chip AX210.

626913_Intel_Wi-Fi_6E_AX210_Typhoon_Peak_2_Product_Brief_v1_2.pdf (178.9 KB)

Then here is the info from Linux Wireless.

https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#firmware

Edit currently it seems to be using this firmware version if i have this correct?

74.fe17486e.0 ty-a0-gf-a0-74.ucode op_mode iwlmvm

Edit: Also please look at the Arch Wiki.

Maybe try other kernel parameters listed.

odlund · June 15, 2023, 8:03pm

Hey, i installed the necessary drivers. added to the config, yet nothing has worked. Thank you for responding to my post up until this point. I think I just have to buy a new network card, really wished something else would’ve worked though.

ricklinux · June 16, 2023, 12:19pm

You could try disabling AX mode to see if it’s faster by adding options iwlwifi disable_11ax=1 to

/etc/modprobe.d/iwlwifi.conf

jrichard326 · June 16, 2023, 3:33pm

Since nobody mentioned it… It sounds like OP is dual booting Windows. If that is the case, is Windows fully shutdown, hibernation, fast start and hybrid sleep all disabled?

ricklinux · June 16, 2023, 6:24pm

@odlund
Forgot to ask if you have the Fast Startup Feature in Windows disabled under power management.
