usually the wireless on my laptop is fine except at the coffee shop where I study a lot. Get shoddy connection, but more troubling than that, sometimes I can't get an IP from the router at all while my friends are browsing away, and a reboot usually fixes it. Even more troubling is that sometimes i'll get little CPU "hiccups" when the connection is poor. They roughly correlate to these in dmesg:
[ 947.632309] ath9k: RX failed to go idle in 10 ms RXSM=0xdeadbeef
[ 954.851954] ath9k: timeout (100000 us) on reg 0x806c: 0xdeadbeef & 0x01f00000 != 0x00000000
[ 954.852125] ath9k: RX failed to go idle in 10 ms RXSM=0xdeadbeef
when I get this hiccups it will stutter my music player regardless of its nice priority. I try unloading and loading ath9k but that doesn't change anything. Anyone have any ideas?
