I have an Intel(R) PRO/100 VE Network Connection and I use this to connect to my router. However, I can not actually get on-line.
When I check the status of the connection, it says that it is connected under the General Tab but if you press the support tab, where it says connection status, the IP Address, Subnet Mask and Default Gateway fields are blank.
I've attempted to Repair the connection, only to be told that TCP/IP is not enabled for this connection (it was!). So I check to see if I there's a problem with the TCP/IP Settings, only to be told that "In Order to Configure TCP.IP Settings, You Must Install and Enable a Network Adapter Card". There is already a Network Card installed and Windows sees it in Device Manager; in fact, the LAN Properties window even allows me to access Intel's Configuration Dialog Box.
I have since tried a friends usb wireless adapter on my PC and it can connect to the internet perfectly.
