To maintain a stable connection to the UC Davis Wireless Network, your computer must support the ICMP echo request (ping) function. The Windows Firewall installed by Windows XP Service Pack 2 may not respond to such incoming ping requests, even if you had previously enabled ping in ICF (Internet Connection Firewall). In order to prevent frequent disconnections from the UC Davis Wireless Network, you must enable ICMP echo request.

Instructions for enabling ping for Windows Firewall

1. Open the Control Panel (Start Menu > Control Panel; or Start Menu > Settings > Control Panel)
2. Open Windows Firewall (click Network and Internet Connections then Windows Firewall; or double-click Windows Firewall
3. On the General tab of the Windows Firewall dialogue box. Make sure that the On (recommended) radio button is selected
4. Click the Advanced tab
5. Highlight your Wireless network connection and click the Settings button
6. Go to the ICMP tab
7. Check the "Allow incoming echo request" box and click on OK, and then OK again
8. Close the Control Panel
