Having some serious problems with my computer establishing a wireless connection. Here's the situation: I have a desktop which I have a Linksys Wireless G adapter connected to. I'm trying to connect to a linksys wireless router that someone forgot to put security on. I DO NOT have physical access to the router, unfortunately. Obviously I can log in to the router using the default IP/admin password, so I do have access to that.
My computer can recognize the network and connect but once it's connected it has no Internet access. I tried using the static DNS trick listed here : Windows 7 DNS server not responding
That worked for about 4 hours, then stopped. Now the troubleshooter is telling me the same thing - that it can't communicate with the device or resource (primary DNS server)
I'm running Windows 7 obviously, but if I can provide more information let me know.
Any help would be great.
