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. -- Best regards, Michaël
