Advertisements Posting this in case it may help others. I searched the Tivo web site and these forums but did not find a solution. I got a Tivo S3 for Christmas 2006. I set it up with the official Tivo WiFi USB adapter. My network setup is a Netgear WGR614 router and WG602 Wireless access point in the room next to the Tivo. Everything worked fine except that after a few days the daily update failed with a message "Gateway Not Found". The status indicated the WiFi was connected with excellent signal strength. I ran a connection test which also failed. I ran the network setup again without changing any settings. Ran the connection test and it passed. Connected for an update and everything was fine. A few days later, the update failed with the same message. This went on for some time. Every few days I would check the Network settings and after 2-3 days the update would fail with the same message. I tried various changes including setting a fixed IP on both the Tivo and my Router. I upgraded the rounter and access point to the latest firmware. The problem still occurred every 2-3 days. The solution I found was to disable the DHCP client on the access point and manually set a fixed IP Address, subnet mask and Default Gateway address for the access point. I also assigned the fixed IP for the Tivo but I'm not sure that is necessary. It has been almost 2 weeks now and no update failures so I'm pretty sure the problem is fixed.
