This doesn't make any sense! Surely modems and routers don't connect like this?

You have an IP address conflict between the Zyxel and Linksys; Linksys also uses 192.168.1.1 for its LAN address. You'll need to change the LAN address for the Linksys to resolve the conflict. You may want to reset the Linksys to factory defaults and start from scratch.

- Connect you computer to one of the LAN ports (not the Internet port) on the Linksys. Don't connect the Zyxel at this time.

- Access the Linksys GUI through your browser. http://192.168.1.1

- On the basic setup page, change the Local IP to 192.168.2.1 and save settings. You'll lose access to the page after doing this, but you can verify the change by using the new IP to access the GUI.

- Reconnect your modem to the Linksys Internet port. Reboot modem, router and all devices.

The exact steps depend on your Linksys model, but the basics are the same.
