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Most common: Bad or outdated router firmware (client-side) Less common: Bad or outdated router firmware (server-side) If your connection to most servers fails with one of the error messages listed above (or you experience the other symptoms), this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.

Troubleshooting

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

Linksys BEFSR11, 41 and 81 routers seem to be causing this a great deal with the latest firmware version available from their website. If you have the BEFSR11 or 41 router, you need to run the 1.45.7 firmware to solve this problem. The current firmware version that Linksys has on their website: (1.45.11) and some older versions (before 1.45.7) of the firmware can cause these same problems. You can download the known good Linksys 1.45.7 firmware for both the BEFSR11 and BEFSR41 V2 routers at:

LinkSYS Firmware Update

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

Recommended steps:

• 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.
• Disable Wireless Zero Service (included in Windows XP). You can access these settings in Control Panel > Administrative Tools > Services.
