Wireless network -- connected to network but no internet?

I have a secure network that has worked fine for a few years. I have an old computer in the basement that I don't use much -- last time was about 3 months ago. Today when I went on the computer, I was connected to my network as always, but for some reason I can't get on the internet (file sharing %26amp; printing works fine). I never had this problem before on this computer %26amp; all other computers on the network work fine. I've disabled all firewalls but I can't get any browser to work. The only thing that has changed in the last 3 months is that I added a PS3 to the network. Any suggestions?

Wireless network -- connected to network but no internet?
The problem sounds like to be DNS, firewall or default gateway. Check the following:





Check the current IP settings on your computer:





Start-%26gt;run-%26gt;cmd, enter "ipconfig /all" command and check that actually you have configured the correct IP address, Netmask, default gateway and DNS servers.





Now lets check connectivity, ping another computer from your PC on the same network. If it works it means that your IP addressing is fine.





Then ping your default gateway. If it works the Default gateway is available.





Then ping internet but do not use a name, use an ip address to check if the DNS is fine. For example instead of ping yahoo.com ping its ip address 216.109.112.135. If you dont get a response check if there is any firewall feature enabled on your default gateway or a NAT issue. If you get a response it means that you can get out to internet





if you have a response try then to ping using yahoo.com if it does not work it means that your DNS servers are not properly configured.





If there is a DHCP server in your network try to get an ip address form it, the server will provide all the necessary ip addresses to get you out to internet.
Reply:try to ping websites to see if you're connected to the internet and so you could determine if it's a firewall issue (start-%26gt;run-%26gt;cmd-%26gt;ping yahoo,com) if you get replies, then you are connected to the internet and might want to boot in safe mode. if you get 'request timed out' you might want to check your other computers (if there are any) to see if they're online.





also, try to surf using your My Computer or the run field (just type any website address and press Enter) to see if any third party browser extensions (ex. google toolbar or yahoo toolbar) are stopping you from getting online :)





good luck!
Reply:I had this same problem in the past. my solution was to reset the router and try reinstalling the network adapter to see if any thing has changed. (When i say reset the router, I mean turn it off and turn it back on). Hope this helps.
