Also seem to be experiencing this issue. Ubuntu gives the error:

Connection failed Activation of network connection failed.

This appears to be fixed on the 4.18.0-18-generic #19~18.04.1-Ubuntu kernel. Also just for completeness, this issue did not occur when using 4.18.0-17 on a network that doesn't use EAP.

Edit: Also, bluetooth works too on this kernel version and latest HP BIOS.

Oh. It still seems to happen and looks like a deauth but the connection doesn't drop like before still :(

Hey, do you mind re-testing with the new version present in master? Thanks.

I'm not currently able to test this, it'll be a few weeks

The disconnects appear to be fixed with the latest version. However it does stop transferring data if you don't use it for a few minutes, which usually requires a disconnect and reconnect to fix.

@thehamsterjam you mean after a period of inactivity? Do you have dmesg logs of that? Probably related to power management.

Yes after a period of inactivity, I did try disabling power saving with rtw_power_mgnt=0 modprobe param, which didn't help. This dmesg log is with no modprobe params.
