For other brands of routers, the set up should be similar. is the default IP address used by Linksys routers. We will use for the IP address of the WeBWorK laptop server (maybe running off a flash memory drive). is the default IP address usually used by D-Link and Netgear brands and is the default IP address for SMC and Belkin brands. These IP addresses can be changed but if you have a router with a default IP address different than, it is probably best to keep the default and to adjust the IP addresses in these instructions accordingly.

Your WeBWorK server will probably be a laptop and may be running off of a flash memory drive. Regardless, you have configure networking (if it hasn't been pre-configured) so that it communicates with the wi-fi router.

  1. Connect the ethernet cable from your laptop (or whatever you are using as your WeBWorK server) to port 1 on router (actually you can use any port)

We have a Linksys WRT310N Wireless-N Gigabit Router available for loan to be used when presenting a WeBWorK Demo Workshop. This router was set up
