I have set up a FreeBSD access point, it is equipped with a ralink based
card and works most of the time. I would appreciate some help for
troubleshooting ``the rest of the time''. Thanks!
First there is nothing fancy about my wirelesse setup, I merely use the
ralink card as an ethernet switch to create a LAN. I therefore
configured my ralink R2600 ral0 interface, an ethernet card and bridged
them together as described in if_bridge(4) or ifconfig(8). Note that
only the bridge has got an IP address. Also, hostapd is up and running,
managing the ral0 interface. This setup somehow works: I can succefully
connect stations to the AP.
However, from times to times, the ral(4) driver emits a `device timeout'
message and the interface is hen stuck. All connections to the AP are
lost and no station would notice the AP anymore.
I could not successfully reset the interface with the sequence:
# /etc/rc.d/netif stop ral0
# /etc/rc.d/hostapd stop
# /etc/rc.d/netif start ral0
# /etc/rc.d/hostapd start
Although it does not emit any error message, the AP remains
undetectable. Rebooting the machine brings back the AP to a working
state, but that is annoying!
I am running amd64/7.2, the ralink chip is reported to be 2600 or 2610
by the kernel.
