I just upgraded my kernel from gentoo-sources-3.1.1 to gentoo-sources-3.2.0-r1 but now my wifi seems very slow and hanging a lot.
pinging google.com shows sometimes 4 results with 50ms then it will hang and show many results of > 10s. Browsing is almost not possible, but with time and patience it DOES load pages.
My wifi card is Network controller: Atheros Communications Inc. AR9485 Wireless Network Adapter (rev 01) using the ath9k driver.
I see no error at all in dmesg.
I barely changed anything in my config, here is the diff between my working 3.1.1 and the non working 3.2.0-r1:
