Wi-Fi slower on Debian 9 than Windows 7 on the same PC

Postby phoenix_art » 2018-02-11 14:28

Dear Community!

I've got dualboot with Debian 9 and Windows 7 - both x64 - on a DELL LATITUDE E6430s. When I do speedtest on speedtest.net I got 50 Mbit slower speed on Debian than Windows.

My /etc/modprobe.d/iwlwifi.conf ->

"options iwlwifi bt_coex_active=0 swcrypto=1 11n_disable=8"

What could I do?

Thanks!

Try commenting out that option and reboot, Debian page says to use this workaround if you have radio conflict with WiFi if you use Bluetooth:

Thanks for the tip, but unfortunately I got less speed after reboot.

Revert that back then, or as seems you are affected by this let it stay but disable bluetooth service (as root or sudo):

Code: Select all
systemctl disable bluetooth.service


Or blacklist bluetooth and/or btusb kernel module/s...

Code: Select all
nano /etc/modprobe.d/blacklist.conf

and put in it:
Code: Select all
blacklist btusb


Reboot... it is shot in the dark, i have no idea how these conflict really.

I had disabled already, because I usually don't use btooth.

Thanks anyway.

Does it perform any better without the configuration file?

My Intel wireless cards seem to perform similarly under both GNU/Linux and Windows (and OpenBSD), fwiw.

I got the solution, now the speed is almost better than on Windows! :)
