The SPA2102 is the latest dual FXS port analog VoIP adapter from Linksys. The SPA2102 features a built in router to separate your VoIP network from other devices or you can use the SPA2102 as your router to connect other devices to on your network.
Connect the ethernet cable from your PC to the LAN port of the SPA2102.
Then connect your cable or DSL modem's ethernet cable to the SPA2102 Internet port. If necessary, disconnect the RJ-11 telephone cable of your telephone from the telephone wall jack. Then connect that end to the SPA2102 phone 1 port. If you have a second telephone, plug that into phone 2 port. Now, power up your PC, cable and DSL modem and your SPA2102.
If your internet connection requires a user name and password (usually only DSL subscribers), you will need the setup instructions provided by your Internet Service Provider (ISP). If you do not have this information, then contact your ISP before continuing.
The instructions from your ISP tell you how to setup your PC for Internet access. Because you are now using the SPA2102 to share Internet access among several computers, you will use the setup information to configure the SPA2102 instead of the computer.
