I would appreciate any help available! I was building a WAP using a PC Engines ALIX board (AMD Geode LX800), DNMA92 wireless card (Atheros 92xx) and Voyage Linux (based on Debian Lenny, 2.6.30 kernel with hostapd 0.6.9 and libnl1.1). It was all working but, the wireless card would drop connectivity for no apparent reason after an undetermined time (minutes to hours). Stations (Win or cellphone) would no longer see it at all, as if it was no longer transmitting. The Voyage maintainer advised that ath9k isn't that stable at 2.6.30. So, I upgraded the kernel to 2.6.32 using the Debian Lenny backport. I then installed the "stable" compat-wireless, 2.6.32.16. Hostapd appears to start OK. However, the wireless SSID is only visible to the Windows clients for a short time - seconds/minutes - and they aren't able to connect. There were no errors in the hostapd startup and it does its key rotations periodically. All that's logged from hostapd -dd during the actual time that the Win clients can see it and are trying to connect is: 1278785975.350851: STA 00:13:02:be:7b:f9 sent probe request for broadcast SSID 1278785975.353034: MGMT (TX callback) ACK 1278785975.353073: mgmt::proberesp cb (repeated a few times) The Win7 station used to connect automatically but now doesn't and when I click "connect" it fails and shortly thereafter the SSID disappears from the list. Nothing in /var/log. iw phy phy0 info and iw dev wlan0 info appear to report sensible info as does iwconfig. During boot I do get messages about "VIA Padlock Hash Engine not detected" and modprobe: FATAL: Error inserting padlock_sha (/lib/modules/2.6.32-bpo.5-686/kern...): No such device >>From googling it's not clear to me at least whether this is relevant. Suggestions? What further diagnostics could I do? Thanks, Norm Henderson
