Hi all!
Talking with some german guys they were having fun on me, because i said
tagged vlan are not working on wdrXXXX switch it seems we are just ignorant
and we are missing some knowld on how switch works on openwrt they said to me
that they tried on wdr3600 and it works fine and pointed to me to this page
http://freifunk.in-kiel.de/wiki/Konfiguration/Eigenes_WLAN
I do not have tp-link with me but i'll implement that as soon as possible and
hope someone with tp-link in hand can help me testing
