    Im lost now.. Can you describe your home network including the model numbers of the routers, switches and Hubs.

    I am thinking what you are describing as a Hub is actually a NAT router.

    Starting from comcast cable in to comcast modem. Modem > Linksys BEFSR41v4 router all located on my second floor in the office. Flow on second floor > the Linksys router > Netgear Ethernet Hub EN104> premiere in MBR. 1st floor flow in LR. From Linksys router in 2nd floor office > Netgear wireless router WNR 2000 (acting as access point) > sereis 2 TiVo hard wired and also a second series 2 wireless. That is all that is germain to this issue.

    Currently I have changed up the connection and eliminated the Netgear Hub so on the second floor everything is connected to the Linksys router only.

    I think the problem is with the Netgear WNR 2000 can you temporary replace it with the Netgear HUB? At least for the wired Series2

    I would agree with you HomeUser and that is what I thought at first. So for troubleshooting purposes I eliminated the Netgear WNR 2000 as well as the ethernet hub EN104. So I had the premiere and one of my series 2 connected to my Linksys router with nothing in between and this did not fix the problem.

    Wow, Maybe Bshrock is on to something with the Linksys firmware update. Have you done anything special in the Linksys settings? I am assuming the Linksys router is the NAT, DNS and DHCP server.

    The linksys is a small home router. I do not think it has NAT functionality. DHCP doesn't apply as the tivos have static IPs that are outside the DHCP range of the router. I am going to try upgrading the firmware. However most of the updating probably affects routing to the WAN. The LAN should be a more simple pass through. I am tempted to try a switch and connect everything through the switch. That way all LAN traffic would not even go through the router.

    Oops I guess I am wrong. My router does have NAT

    Because they all have fixed IP's you can eliminate problems in routing by using the HUB for all the DVR's then replace the hub with the routers.

    Why didn't I think of that. I do not understand the second part. Why would I replace the hub with the routers. If I got it to work I would just leave the hub for for TiVo traffic.

    Problem with the Hub is there is no isolation between devices. When 2 devices transmit at the same time results collisions forcing both to re-send the packet reducing the throughput.

    Maybe the Premiere software got upgraded to IPv6, and now it's too snooty to have anything to do with the IPv4 S2s.

    Problem solved. I connected all my tivos to my hub and low and behold I can see the premiere. On the first floor I still am connected to the Netgear WNR 2000 that is acting as a wireless acess point and then to the hub. In spite of this it still works fine. So the problem was with the main router the linksys.

    I know that hubs broadcast and switches build an ARP table on the first broadcast so it can forward to a singe port using mac addressing. Ideally I want to get a switch that is large enough to handle all the devices on my LAN.

    Or look at the settings of the routers and when you figure what needs to be changed report back what you find to help others with the same issues.

    Figuring out the settings on the router is above my head at the moment. Before I tried switching the tivos to the hub I disabled NAT on the router. When I did that I could not connect to the internet. currently I do not understand why that is, but I will. Tivo support gives out a list of inside ports that should unrestricted. I never opened up those ports. I do not want to open ports and reduce my security. Also I and experts I know have never heard where LAN ports are restricted by a router. I have been taught that the only ports are firewall ports that restrict traffic going in and out to the internet. I may try connecting back to the router just to see what happens. I may updat the firmware or upgrade to DDWRT and then see what happens. However best practice would be to have a switch forwarding all LAN traffic thereby only using the router to route to the internet. Why have a layer 3 device doing layer 2 tasks?
