Hey! I am having a similar problem. I have moved into a new apartment with internet connection already here, and am trying to get my TP-Link TL-WR542G router to work with it. I have managed to manually set up the router several times with different address numbers (at the moment 192.168.1.10) and can manage to connect to where the little lights on the network diagnostic tool get to "ISP" in green, but the Internet and Server is always in yellow. I can connect through the cable straight to the net, so I know it's not the connection, it has to be my router, but I am completely stumped as to what else to do. Unfortunately I cannot call my isp for help as I am in a non-English speaking country and they can't help me no matter how much I scream at them!

Any advice you can give this frazzled lady would be greatly appreciated! I am at my wits end! Thank you!!!!
