Just replaced my router with a new ASUS RT-N66U. For everything on the network other than Tivo it is working great. Except none of the Tivos can complete a connection. Tivo reports Failed during configuring. Or on trying to test the network connection it reports failed to obtain account status. I can see the TiVo's on the network. All three are configured with static IP addresses. Kmttg can download from them. I can see pytivo and pull a video. Cannot push as none of my TiVos are connecting with the service. Is there some incompatibility of this router with Tivo or my ATT DSL connection? I did read some earlier posts about setting MTU to 1492 for a DSL connection but this router has no settings for MTU other than for PPOE connections which does not apply to me. Perhaps just the wrong router? My previous Linksys E3200 router works but has gotten very slow. If not the ASUS, can someone recommend a new router that has decent performance and configurable QoS?
