Also, here's some copy paste from forums I found on how to out your isp router into bridge mode, in case you truly need it for TV:
Select ADVANCED SETUP Select PROCEED at advanced user challenge screen Select WAN IP ADDRESSING under the IP ADDRESS section on the left-hand menu. In SECTION 2, Select RFC 1483 Transparent Bridging Select Apply to save any changes at bottom of screen. The "Internet" light on the front of the modem should go solid RED. This indicates the modem is in Bridge mode.
