• Update router or home gateway firmware. If your home network
uses a router, home gateway, or wireless access point, it may
need a firmware update. Firmware is a software program that is
loaded onto a hardware device. You can usually find any
updated firmware at the Customer Support website for the
manufacturer of your hardware.

TiVo Premiere 4/XL4, check that its IP address is unique on
your network. Also, confirm that the first three sets of numbers
of the TiVo Premiere 4/XL4's IP address are the same as those
of other devices on the network. (For example, if your
computer's IP address starts with 192.168.1, then your TiVo
Premiere 4/XL4's IP address must also start with 192.168.1.)

screen. If you do not see a MAC address listed, the TiVo
Premiere 4/XL4 does not recognize the network adapter you

• Check connection to the network adapter. Unplug the network
adapter from the back of your TiVo Premiere 4/XL4, wait 10

cable is pushed all the way in.

access point or wireless router is receiving power and that the
"link" light is on.
