The internet was working fine until yesterday, so this has me baffled. Wired computer is fine. The wireless computer can ping the router, but not ping any external websites (google.com). Here are the settings: DHCP Enabled: No IP Address: 192.168.1.30 Subnet Mask: 255.255.255.0 Default Gateway: 192.168.1.10 DNS Servers: 192.168.1.10 not sure what other information might be useful. again, i can ping the router through cmd, but can't access any websites, nothing that requires an internet connection works. I cant even access my router through the browser (IE7). Please help...

Have you done a power or soft reboot of the router? Can you access the router admin interface from the wired PC? I've occasionally had the wireless part of my router cease working and a reboot of the unit resolves the problem. Goin' Fishin' (Some day)

Strikes me as odd IP addresses. Seems like you put those numbers in for some reason. If it did work before with those numbers then maybe the router got reset somehow. Try the default ip settings. Might have to use dhcp on your computer or put static in that is in the subnet of the default ip of the router.

Try to ping 4.2.2.2. If you get a reply, you can actually get out to the Internet, but if pinging google.com or yahoo.com does not return anything, then sounds like a DNS issue. (DNS resolve friendly names like yahoo.com to IP addresses.) Your settings indicate the router is supposed to be doing DNS resolution for you. You can try manually setting the the DNS IP address in your IP settings to the DNS addresses used by your ISP, or you can try the generic 4.2.2.2, 4.2.2.3, and 4.2.2.4 and see if your able to ping website names or bring up webpages that way. (But even with no DNS resolution, you should still be able to bring up your router config page using 192.168.1.10. If not, sounds like good chance you have router problems.) Assume that I already did an Internet search.

Does your wire network work? go into the router and look for your ISP DNS IP address and then statically assign it to your wireless card! On the way to becoming the greatest Cisco and Microsoft expert!

I did try a reboot, where I basically unplug the power cord from the router, wait about 30 seconds and plug it back in. But that didnt fix the problem. I don't see any IP address on the router itself, but my service provider is AT&T and it is an AT&T router. I am able to ping 4.2.2.2, but again, not google.com or yahoo.com. Not really sure what to do. The settings i put in my original post were done by someone else whom i no longer have access to, but it was supposedly to make it more secure or soemthing... I'm really not too knowledgable... all i know is that it was working one day (for a few years) and not working the next day. any other suggestions? I appreciate the responses =)

If you can ping 4.2.2.2, but not google.com or yahoo.com, then it's a DNS issue. - Try right clicking My Network Places and click Properties. - Right click on your network adapter icon, usually says "Local Area Connection..." and click Propeties. - In the conneciton properties window, scroll down and double click "Internet Protocol (TCP/IP) - Change the settings to "Obtain IP address automatically" and "Obtain DNS address automatically". Reboot for good measure. If it still doesn't work, you'll just have to contact your ISP tech support people. Assume that I already did an Internet search.
