Updated immediately after the extreme slowdown problem occurred and fixed itself (experienced for ~8 minutes?).
This was also in /var/log/syslog, and seemed relevant. The problem started somewhere around the time of the second- or third-to-last line, and was fixed immediately after the last line appeared: Dec 26 14:37:03 eryn-ultrabook wpa_supplicant[1218]: WPA: Group rekeying completed with 02:1a:11:fd:16:63 [GTK=CCMP] Dec 26 14:47:03 eryn-ultrabook wpa_supplicant[1218]: WPA: Group rekeying completed with 02:1a:11:fd:16:63 [GTK=CCMP] Dec 26 14:51:23 eryn-ultrabook dhclient: DHCPREQUEST of 192.168.43.39 on wlan0 to 192.168.43.1 port 67 Dec 26 14:51:23 eryn-ultrabook dhclient: DHCPACK of 192.168.43.39 from 192.168.43.1 Dec 26 14:51:23 eryn-ultrabook dhclient: bound to 192.168.43.39 -- renewal in 1401 seconds.
