Bug Description
Running Intrepid on an Eee PC 900, kernel linux-image-
01:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)
I'm getting frequent dropouts on the wireless, maybe every 1-2 minutes when it's in heavy use. daemon.log shows something like this:
Oct 5 14:08:44 eee NetworkManager: <debug> [1223240924.781343] periodic_update(): Roamed from BSSID 00:11:22:33:44:55 (networkname) to (none) ((none))
Oct 5 14:08:45 eee NetworkManager: <info> (wlan0): supplicant connection state change: 7 -> 3
Oct 5 14:08:46 eee NetworkManager: <info> (wlan0): supplicant connection state change: 3 -> 0
Oct 5 14:08:46 eee NetworkManager: <info> (wlan0): supplicant connection state change: 0 -> 4
Oct 5 14:08:46 eee NetworkManager: <info> (wlan0): supplicant connection state change: 4 -> 7
Oct 5 14:08:50 eee NetworkManager: <debug> [1223240930.785415] periodic_update(): Roamed from BSSID (none) ((none)) to 00:11:22:33:44:55 (networkname)
(changed MAC and SSID)
Sometimes the 'supplicant connection state change' section goes on for quite a while, maybe almost a minute. During that time the wireless is dead. Sometimes the 'supplicant connection state change' start up without the roaming messages (and the wireless again is down).
This is on a WEP network with a 64-bit hex key.
I saw some bugs that looked fairly similar, but not quite identical, so sorry if this is a dup.
Thanks for any help.
Hi,
on my eeepc 701, I have the same problem. Network-Managers seems to login in my wlan-network (WPA), but the speed changes very fast from 6MBit to 48MBit and back, although with hardy and madwifi, the connection is stable.
pings are sometimes lost.
I hope, this helps
Greeting
Klaus
