How can I debug further? Message-ID: <4C5566A1.2040500@mintsource.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ath9k-devel@lists.ath9k.org Hi all, I have a Macbook Pro late 2006 model, with an ath9k (5008) wireless adapter that often (approx 10 times a day) appears to pause connectivity for a few minutes, before deciding it needs to re-authenticate. Can anybody advise me on the next steps to take, so I can get more information useful to solving this problem? Looking over my logs and other information, I couldn't find anything that would be solved following advice I have found online. I am using an up to date Arch Linux system, and have also tried the compat-wireless-2.6.34.1 stable kernel release. I had used network manager and it's applet at first, but I was unable to even re-authenticate with that, so I'm using wicd. Many thanks, Si ....info. When the connection "hangs", ifconfig & iwconfig show the following, just like it's still working: wlan0 Link encap:Ethernet HWaddr 00:17:12:1D:18:28 inet addr:192.168.1.10 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:448116 errors:0 dropped:0 overruns:0 frame:0 TX packets:317888 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:554291095 (528.6 Mb) TX bytes:74539778 (71.0 Mb) wlan0 IEEE 802.11abgn ESSID:"Mintsource 2.4GHz" Mode:Managed Frequency:2.432 GHz Access Point: 30:16:1A:16:14:AD Bit Rate=216 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=53/70 Signal level=-57 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 Leaving a terminal window open, pinging the router, I can see that no feedback is now coming back from ping, and all other connectivity is suspended too, but a few minutes later ping starts responding: ping: sendmsg: Network is unreachable At this point, other apps also give error feedback, but ifconfig and iwconfig don't respond much differently than before: wlan0 Link encap:Ethernet HWaddr 00:17:12:1D:18:28 inet addr:192.168.1.10 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:448329 errors:0 dropped:0 overruns:0 frame:0 TX packets:318349 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:554304167 (528.6 Mb) TX bytes:74609967 (71.1 Mb) wlan0 IEEE 802.11abgn ESSID:"Mintsource 2.4GHz" Mode:Managed Frequency:2.432 GHz Access Point: 30:16:1A:16:14:AD Bit Rate=216 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=52/70 Signal level=-58 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 Kernel.log reports nothing until the re-auth.
