Known Causes

  • Most common: Bad or outdated router firmware (client-side)
  • Less common: Bad or outdated router firmware (server-side)

If your connection to most servers fails with one of the error messages listed above (or you experience the other symptoms), this is a firmware issue with your router.

If your connection to one server fails, it is likely a problem with the network the server you are trying to connect to is operating on.



If you have a stand-alone router, bypass your router and plug directly into your modem to see if the connection continues to fail.

Please visit your router manufacturer's website for Firmware updates. If you have questions about installing or updating your Firmware, please contact the router manufacturer for assistance.

ActionTec DSL Modems which encounter this problem will need to be replaced, as no firmware update is available.

Recommended steps:

  1. Disable QoS and uPnP. You need to go into the router and disable UPnP and QoS if it's there, and you should only have TCP/IP checked in the network properties for your Internet connection.
  2. Disable Wireless Zero Service (included in Windows XP). You can access these settings in Control Panel > Administrative Tools > Services.
