ath5k will frequently drop the wireless connection. This happens about once every two hours. I have to do `/etc/init.d/net.wlan0 restart` to reconnect. The drivers from Madwifi-ng with an older kernel DO work (it is what I was using before upgrading to 2.6.30-r1). `uname -a`: Linux lap 2.6.30-gentoo-r1 #1 SMP PREEMPT Fri Jun 19 04:48:01 EDT 2009 i686 Intel(R) Celeron(R) M processor 1.40GHz GenuineIntel GNU/Linux Reproducible: Always Actual Results: Expected Results: This is what /var/log/messages looks like (cron messages are removed): (I was disconnected, so I ran `/etc/init.d/net.wlan0 restart`) Jun 24 16:27:21 lap dhcpcd[10478]: wlan0: received SIGTERM, stopping Jun 24 16:27:21 lap wlan0: deauthenticating by local choice (reason=3) Jun 24 16:27:21 lap wlan0: direct probe to AP 00:18:39:da:1a:17 try 1 Jun 24 16:27:21 lap ADDRCONF(NETDEV_UP): wlan0: link is not ready Jun 24 16:27:21 lap wlan0 direct probe responded Jun 24 16:27:21 lap wlan0: authenticate with AP 00:18:39:da:1a:17 Jun 24 16:27:21 lap wlan0: authenticated Jun 24 16:27:21 lap wlan0: associate with AP 00:18:39:da:1a:17 Jun 24 16:27:21 lap wlan0: RX AssocResp from 00:18:39:da:1a:17 (capab=0x11 status=12 aid=0) Jun 24 16:27:21 lap wlan0: AP denied association (code=12) Jun 24 16:27:21 lap wlan0: authenticate with AP 00:18:39:da:1a:17 Jun 24 16:27:21 lap wlan0: authenticate with AP 00:18:39:da:1a:17 Jun 24 16:27:21 lap wlan0: authenticated Jun 24 16:27:21 lap wlan0: associate with AP 00:18:39:da:1a:17 Jun 24 16:27:21 lap wlan0: RX AssocResp from 00:18:39:da:1a:17 (capab=0x11 status=12 aid=0) Jun 24 16:27:21 lap wlan0: AP denied association (code=12) Jun 24 16:27:21 lap /etc/init.d/net.wlan0[15640]: Trying to force preferred in case they are hidden Jun 24 16:27:21 lap wlan0: authenticate with AP 00:18:39:da:1a:17 Jun 24 16:27:21 lap wlan0: authenticated Jun 24 16:27:21 lap wlan0: associate with AP 00:18:39:da:1a:17 Jun 24 16:27:21 lap wlan0: RX AssocResp from 00:18:39:da:1a:17 (capab=0x11 status=0 aid=3) Jun 24 16:27:21 lap wlan0: associated Jun 24 16:27:21 lap ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready Jun 24 16:27:22 lap dhcpcd[15708]: wlan0: dhcpcd 4.0.13 starting Jun 24 16:27:22 lap dhcpcd[15708]: wlan0: broadcasting for a lease Jun 24 16:27:23 lap dhcpcd[15708]: wlan0: offered 192.168.1.110 from 192.168.1.1 Jun 24 16:27:23 lap dhcpcd[15708]: wlan0: acknowledged 192.168.1.110 from 192.168.1.1 Jun 24 16:27:23 lap dhcpcd[15708]: wlan0: checking 192.168.1.110 is available on attached networks Jun 24 16:27:28 lap dhcpcd[15708]: wlan0: leased 192.168.1.110 for 86400 seconds Jun 24 16:27:31 lap wlan0: no IPv6 routers present Jun 24 16:27:58 lap ntpdate[15794]: step time server 128.10.252.6 offset 0.983321 sec (Then this happens about an hour later.

Well, I feel dumb. I figured out it was just a household wireless phone interfering with the signal. Whenever anyone used the phone, the computer would lose the connection to the wireless router. I changed the wireless router to a different channel and completely solved all of my problems.
