peterh 1 Posted April 10, 2007 Open start, run, cmd.exe and type IPCONFIG /ALL, then let us know what your setup is? How are you connected to internet? Wireless router, wired router, or usb modem or 56k modem? Share this post Link to post
Myke 0 Posted April 11, 2007 While in the command prompt, try releasing and renewing your IP. 1. type IPCONFIG /RELEASE 2. type IPCONFIG /RENEW 3. type EXIT If your issue still ocurrs, then it might be a router configuration problem. Try unplugging everything from your router, including the power cable. After 30 seconds, plug in your router's power cable and wait for the self-test to complete. Then plug your computer's ethernet cable into the router. Afterwards, repeat steps 1-3 above. Share this post Link to post
Wilhelmus 1 Posted April 11, 2007 You'll need to run the command prompt with Administrator rights before you can use the ipconfig command properly (right-click the command prompt shotcut in start menu and select Run as Administrator). Share this post Link to post
