Internet but no internet?

I have a network with three computers on it. Two connected physically (RJ45) to the router, a third connected via wireless. It's a linksys router, with a dlink USB device to connect via the wireless.

I am in a situation where the two physical connections work fine...the wireless appears to as well, but I can't seem to get the internet to work. It acquires an IP address, I can talk to the router, log into it, check the settings etc. But when I try to run internet explorer or firefox it won't load any of the pages. I've tried reseting all portions in various combinations, releasing and renewing both the WAN address on the router and the address on the wireless computer. Tried shutting off all the other computers etc. Nothing. Tried disabling the firewall, disabling any other potential connections. Nothing. And it all seemed to start spontaneously.

Any advice?

No, I cannot ping outside the network, it says something like "host not found". If I'm not getting a gateway, how do I solve that problem?

Settings are identical, except the obvious difference in the physical MAC address and device type.

Other ideas?

I've tried reseting the router numerous times, also tried reseting the DSL modem, try punching in the gateway manually, nothing. Went back to automatic, nothing.

Any other ideas?

Deleted, rebooted, reinstalled, nothing. Letting windows automatically set it up, been through virtually every setting I can think of, nothing.

It's like it's not querying the wireless when I try to access the internet. If I punch in the router address, the activity light on the d-link flickers, if I punch in an internet address, it doesn't, at least no more than it does when the computer is sitting idle.

I thought about the stacks or winsock as well, I had that problem in the past with another system, but in that case as I recall I couldn't access the router either...though I could be mistaken, it was a long time ago.

Any other ideas? Any thoughts on forcing the internet connection to the wireless? I've disabled all the other network devices, still nothing.

Any thoughts? Your help is appreciated.

Have you tried pinging via IP? It could very well be a DNS issue. One of google's addresses is 64.233.161.104. Try pinging that.

If you are able to work the local subnet, your stack is fine as well as the wireless card. It has to be either DNS or a routing issue.

If it's a DNS issue. All ISP run there own DNS Servers. It's possiable their servers went off line, but rarely more than a could hrs, reason most have 2.

It's possiable that your router is either not getting it from the ISP or your router is not passing it on to you.

I would recommend doing a power cycle of the modem and router and PC. Then check to see if the router pulled the info from the ISP. If not check your router settings.
