Hello
I have just bought TL-WA801ND and I dont know how to connect it to my dsl router.
When I was using my old router all I had to do is to change in WAN tab option to STATIC IP ADDRESS and then put my IP address, gateway, DNS.
Here at TL-WA801ND I see no wan option. There is only Lan tab - there is option to change Lan to static Ip-address but It does not work like wan - there is no field for DNS.

Is there anyway to connect my DSL modem to tp-link ? I am connecting DSL modem with ethernet cable and as I said at tp-link I should put (Ip address, gateway, DNS).
