Hi,
I've just discovered one issue in the network settings / documentation.
When configuring / bringing up the bridge interface br0 before the switch eth0.0 and wireless ath0 interfaces were up I was getting errors - undefined / nonexistent interface. The bridge script was trying to include interface(s) which doesn't exist yet.
The resolution was to move the bridge br0 interface configuration part in the /etc/network/interfaces file to the end of file just after the switch eth0.0 and wireless ath0 interfaces config parts.
I am using FreeWRT 1.0 on my WGT634U, but I believe it is a rather documentation issue.
Regards,
Stano
