Ok I have 3 Tivos Tivo 1 is a Premiere (Tivo-LR) Tivo 2 is a S2DT (Tivo-FB) Tivo 3 is a S2DT (Tivo-BB) Tivo-LR can see both S2 tivos. but the S2 tivos only can see the S2 tivos and not the premiere. I have go online disabled View sharing, run updates waited until tivo2go showed i,i,i and the reenabled view sharing. waited until tivo2go showed a,a,a. But still not working. This started about 3 weeks ago. Around that same time I switched out the router/modem. Not sure it it stopped working before or after. I had a 2Wire DSL Modem/Router, switched to a Zyxel PK5001Z modem/router. All 3 tivos are hardwired. All are in the same subnet. All has same Ip #s 10.9.0.2, 10.9.0.3, 10.9.0.4. subnet 255.255.255.0.
