Look at this ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 2290 ether cc:b2:55:00:68:1f media: IEEE 802.11 Wireless Ethernet autoselect mode 11ng <hostap> status: running But when freebsd creates wlan0 it's lowered to 1500. I tried with another ath WiFi card this way - worked fine with 2290 MTU in a bridge. BTW 2290 is max value, but it seems than noone looked into wifi MTU under freebsd, theoretically it could be about 7k to 9k - normal jumbo frame. 2290 is some kinda way of baby jumbo frames - they're slightly bigger than 1.5k. So next is the bridge. By default bridge uses the MTU of a first member, so if it will be a stock ethernet i-face so it'll be again 1500. If you're asking me why am I to use increased MTU - I see it reasonable. > you also don't need to say ht, it'll automatically do ht for you. > > -a > -- amd_miek Think different. Just superior.
