I am not sure where to place this question so here goes.
My old linksys "G" router died after the power surge from Superstorm Sandy. Before the storm I had the linksys router connected to my cable modem in another room. I purchased Netgear WN 2000RPT Universal Range Extender containing a 4 port hub as a wireless hub and wired my TiVo into that. Everything worked great. The Hub saw the wirelss router and the TiVo saw the hub.
Yesterday, I purchased a new Netgear Dual Band N600 WNDR 3400 router and set everything up. All of my wirelss devices see the new router and work great and according to the indicator lights on the hub it sees the wirelss router. The TiVoHD in the room with the new router is plugged in directly and works fine. I have used the same SSID and Password on both devices. All of my wirelss PC's and iPhones can access and log into the internet through the Extender. However the TiVo, even though it looks like it was assigned an IP address 192.168.1.5 cannot access the internet. I contiue to get a message stating during configuring that the network cable is unplugged and I cannot access the internet. Also, the TiVo runs very slow now and trying to click through the menus can take minutes. I did not makes any changes to the new router and accepted all defaults including the SSID and password. I did change the SSID and password on the extender to match the router. The security protocol the SSID and the router use is WPA2 (I hope I am stating this correctly).
