Hi,
I'm running Arch on a Thinkpad T440p. I have some large, long-running downloads to finish, but I've been finding that leaving them running overnight hasn't been working. Although I don't know exactly what's happening yet, it seems like no/next-to-no progress is made overnight despite things coming down at reasonable speed when I leave them.
I've tried the obvious things: I have TLP installed and wireless PM turned off when on AC power. iwconfig confirms that power management is off for my wireless adapter. Obviously automatic suspend on AC power is also off in the GNOME settings. I'm blanking my screen after 15 minutes - and would ideally like to continue doing so.
If it makes any difference, I'm using an OpenVpn connection. Through the night I'm seeing this sort of thing every 20 minutes or so (this log is in reverse order, latest to earliest):

I'm not sure whether to interpret that as the wifi waking up periodically, and trying to reconnect to the router, or if it's consistently on but occasionally losing connection.
I've just tried setting my regulatory domain for the wifi card (which wasn't set previously) - not sure if that will make any difference. Any pointers on things I can do to acquire more info/debug this further? Or just some obvious setting that I've missed that's worth changing?
Cheers
