As mentioned in the "2.6 kernel and b43 driver", I now have my b43
driver working as a WPA client, but I see some strange problems of ssh
connections freezing every once in a while.
As mentioned, when such a connection freezes, ping still works.
Better yet, here's a tcpdump of the communication between my desktop
"pastel" (using rt73usb) and my wl700ge "proxy" (running the b43 driver)
with an ssh connection frozen, where "home" is the AP (some other home
router, running supposedly some kind of *BSD derivative with an Atheros
card, IIUC the syslog output):
02:58:19.805177 arp who-has proxy (Broadcast) tell home
02:58:31.248256 IP pastel.33328 > proxy.ssh: P 240:288(48) ack 1 win 103

02:58:36.250125 arp who-has pastel tell proxy
02:58:36.250135 arp reply pastel is-at 00:17:3f:ac:95:4e (oui Unknown)
02:58:49.978873 arp who-has proxy (Broadcast) tell home
02:58:58.493356 IP pastel.33328 > proxy.ssh: P 384:432(48) ack 1 win 103
02:58:58.497070 IP proxy.ssh > pastel.33328: . ack 432 win 5584
02:59:20.903055 IP pastel > proxy: ICMP echo request, id 44863, seq 1, length 64
02:59:20.907145 IP proxy > pastel: ICMP echo reply, id 44863, seq 1, length 64
Each packet "IP pastel.33328 > proxy.ssh" is in response to my hitting
some key in the SSH session: so clearly, "pastel" sends the message and
"proxy" (i.e. the b43 running machine) receives it and
acknowledges reception.
Anybody has an idea what might be going on, what I might want to double
check and investigate?
I've appended the relevant part of my /etc/config as well as the
resulting `ifconfig' and route.
