My wifi connection has been dying very regularly. I notice when I run netctl-auto enable-all I reconnect within 5 seconds every time. (My connection has dropped twice while posting this.)

Why does this work, and what does this suggest about the actual problem? How can I solve this for good?

If you need more info, please ask and I'll gladly supply it.

I think the output of iwconfig and sudo lspci -nnk | grep -i -A5 network would be awesome. Also, make sure that you are near the access point. – Braiam Feb 21 '14 at 21:45
I don't think it tells us really anything useful towards debugging the underlying issue. Debugging wifi issues is notoriously difficult. Please provide this output: lshw -c network & take a look at dmesg when this issue arises. Include that as well, just the last 20 or so lines should suffice for dmesg. We'll likely be asking for more info so don't get frustrated, debugging these issues is a "process". – slm Feb 21 '14 at 21:46
@Braiam done, and done. – Korgan Rivera Feb 21 '14 at 22:01
@sim okay, done. – Korgan Rivera Feb 21 '14 at 22:07
@KorganRivera - the output from dmesg is that from when the card started to act up and drop? – slm Feb 22 '14 at 1:19
