ProSAFE Dual Band Wireless-N Access Point with RFID Support, WNDAP380R
When You Enter a URL or IP Address a Time-Out Error
Occurs
A number of things could be causing this.
Try the following troubleshooting steps:
•
Check whether other computers on the LAN work correctly. If they do, ensure that your
computer’s TCP/IP settings are correct. If you use a fixed (static) IP address, check the
subnet mask, default gateway, DNS, and IP addresses of the wireless access point (see
Configure the IP Settings
on page
21).
•
If the computer is configured correctly but still not working, ensure that the wireless
access point is connected and turned on. Access it and check its settings. If you cannot
connect to the wireless access point, check the LAN and power connections.
•
If the wireless access point is configured correctly, check your Internet connection (for
example, your cable modem) to make sure that it is working correctly.
Troubleshoot a TCP/IP Network Using the Ping Utility
Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request
packet to the designated device. The device then responds with an echo reply. You can easily
troubleshoot a TCP/IP network by using the ping utility in your computer.
