I still haven't gotten around to testing it myself but afaik you have to use the "swconfig" command line app to configure VLAN's on Atheros models.
For the QoS I don't think even the new GUI (formerly paid premium now free) can do that if you even have it in your build, but it is possibly with tc and iptables commands. _________________ Read the forum announcements thoroughly! Be cautious if you're inexperienced.
Available for paid consulting. (Don't PM about complicated setups otherwise)
Looking for bricks and spare routers to expand my collection. (not interested in G spec models)
