The wlan0 <–> eth0 ethernet bridge I have on my server now essentially works well, apart from a few issues.
The most serious seems to be that the wireless card will suddenly stop working – in the sense of disassociating and then refusing to re-associate. The first time it did this it took 10 days, the second about three: I think this is a known problem – as I read about it when I was tearing my hair out about how to set the thing up, though I cannot find a reference to it now – will keep on searching.
The other is a less serious problem – as I know how to fix it. When the machine comes up the wireless part of the bridge is disabled but can be restarted with:
iwconfig wlan0 mode master
I am not even sure the restart is needed – but I know the combo works.
Here’s the relevant bits of the
