Would you happen to know what the maximum MTU you could use on the wireless interface? For example, if I have an ethernet network that can support jumbo frames like on a gigabit interface, how large of an MTU could I use on the wireless interface. In my case I'm using Atheros wireless devices, so I don't know if that matters. Gus
