Ok, I'll list all the information because it would seem that I have no clue.
I am using (trying that is) a D-Link wireless ADSL Router (model DSL G604T). This computer will be the 'host' on, and I'm trying to set it up. I'm pretty sure I need static IP, so I do the ipconfig thing in 'run', get my ip, default gateway and default gateway. Then I put that info in the TCP/IP part of my wireless properties in Network Connections, but the internet still wont work.
I try putting in 10.1.1.1 but it doesn't work either - it used to but I don't know what happened.
I don't know if this will make sense, this isn't my area I'm afraid, but any help would be immensely appreciated. I'm getting very desperate.
