The title says all, I'm using Windows Vista SP2, with USB Wireless Adapter 802.11 b/g. My router is Charter, Ambit. There is nothing wrong with it, as I had a technician come today and install a new one, and my LAPTOP's wifi and my other desktop's Ethernet works perfectly. My desktop (with a prebuilt Wifi card) doesn't work, however. I have spent A LOT of effort into this, researched all forums and videos, nothing helps. I did this: -Disabled IPv6 -Checked Security Code -Turned on Network Discovery -Made sure there were no microwave ovens... -IP configurations are AUTOMATIC, not preferred. -Checked for new installations in IPV4/6, for clients services and protocals. -Rebooted my modem and computer. -Turned off Firewall/antivirus. -DId scans with Spyware Doctor and AVG (nothing found). -Rebooted WIFI adapter -Updated my driver, and yes it's the latest version. This problem happened suddenly, and I don't know how to fix it. I've been using WiFi on this computer for about 2 years, and it dropped out a few days ago. It'll say Local Only, Identifying Network, Limited Access, or No Connection every few minutes. Mostly Local Only and Identifying. Sometimes the adapter completely bla

But did you checked your internet connection from other computer? If you have a cable then connect to the router directly and check the internet. It is most likely that the router is not connected to internet. Most user computers take the IP from the router acting also as DHCP server and the settings seem to work fine. But the router may be disconnected from the internet. Check using another computer and make sure that the internet is on on the router. Repair the connection after the checkup. ping 192.168.1.1 ping 71.9.127.107 (DNS) ------->is it OK? As your Computer is taking the correct IP, it is not the autoconfiguration IP which is in the range 169.........
