WG602v4 Manual: When I enter a URL or IP address I get a timeout error.

A number of things could be causing this. Try the following troubleshooting steps:

Check whether other PCs work. If they do, ensure that your PCs TCP/IP settings are correct. If using a Fixed (Static) IP Address, check the Subnet Mask, Default Gateway, DNS, and IP Addresses.

If the PCs are configured correctly, but still not working, ensure that the WG602v4 is connected and turned on. Connect to it and check its settings. If you cannot connect to it, check the LAN and power connections.

If the WG602v4 is configured correctly, check your Internet connection (DSL/Cable modem etc.) to make sure that it is working correctly.
