If you keep losing your wireless Internet connection on every computer connected to your network, try one of the following steps:

  • Disable your firewall and/or antivirus software if they’ve been recently changed or upgraded. If this solves the issue, contact the software manufacturer.
  • If you upgraded Windows XP, make sure the Windows firewall isn't running. If it is, disable it.
  • Reboot your network devices
    1. Shut down your computer.
    2. Turn off your modem and unplug it from the power outlet.
    3. Turn off the wireless router by pressing the power button in the back.
    4. Plug the modem in and turn it on. Wait two minutes until it’s completely restarted before moving on to Step 5.
    5. Turn on the wireless router. Wait two minutes until it's completely restarted before moving on to Step 6.
    6. Turn on the computer.

If this doesn’t restore your connection, try connecting your computer directly to your modem. Unplug your modem, wait one minute, then plug it back in. If you can connect to the Internet, turn off your modem and computer, and reconnect your router.
