Go into the Windows firewall and remove anything it has for WoW. Then re-add the game to the firewall. (Should you need assistance, try to Google for the information on the Windows firewall). Here are the port numbers in case you need them:
World of Warcraft & Burning Crusade use TCP port number 3724 to play and UDP port 3724 for in game Voice chat. The Blizzard Downloader, which downloads patches, also uses TCP ports 6112 and the range 6881-6999. Battle.net accounts use port 1119.

Power Cycle your modem and router to reset them and allow them to re-establish a connection to your ISP. Please follow these steps to completely power cycle the devices in your network connection:
- Shut down all computers connected to the modem/router.
- Power down/unplug the router if you use one.
- Power down/unplug the modem.
- Allow to sit for 60 seconds, unplugged.
- Turn on the modem, allow to completely boot up till the front panel connection lights show a steady connection.
- Turn on the router, if you have one, and allow to completely boot up as well.
- Start the computer(s) and allow to completely boot up.
If that does not work, try this:

- Wait a few seconds for a reply that the IP address has been released.
- Type: "ipconfig /renew" (without quotation marks) in the DOS window.
