I have 3 TiVos. The one in the family room is a Toshiba TiVo/DVD model and the other 2 are regular TiVos. They are all connected via ethernet to a router in the home office. We have been successfully transferring shows among the TiVos and to various household computers for ages.

Recently, we modified the router setup on the TiVo in the family room, so that instead of connecting directly (TiVo to USB/Ethernet Adapter to ethernet cable to router), it is connected as follows: TiVo to USB/Ethernet Adapter to ethernet cable to routher to ethernet cable to router (reason: we have a Slingbox also connected to the first router). Now, we can transfer FROM the family room TiVo to the others, but not TO the family room TiVo from the others - the transfers start, but they stop, so far after 0 minutes, 2 minutes, and 18 minutes (all 1 hour shows).

Does anyone know why, or what we can do to correct the problem?

Hmmm....are you doing double NAT with the IP addresses and using different subnets on the two routers? I.e., let's say the original router is using 192.168.1.X, is the second one using 192.168.2.X and connecting it's WAN port to a regular port on the first router?

If you're using the same subnet on both, it could be getting confused as the same subnet should always be on the same network segment, not across a routed connection....if you're doing double NAT as described above, and the family room DVR has a 192.168.2.X address and the others have 192.168.1.X addresses, I'm surprised they even see each other. I think others have said this was a problem, I haven't tried it myself.

To just expand your network, a hub/switch would have been all that was needed. I don't know what a Slingbox is, did that require the second router for some reason instead of a hub/switch? Or do you have the second router configured to just act as a switch on the same network segment? What brand/model are these?

The problem may be something else entirely, I'm just thinking out loud...but those are what comes to mind first.

Replace the Router with a Hub or Switch. You only need one router between your internal network and the internet. Or since you have the hardware already, make sure Tivo, slingbox an cable to second router are all connected to the "Internal" ports of the first router. In this configuration you're just using the switch portion of the box.

Hi HiTech. I don't know the answer to all your questions, but here's why we added the additional router. Slingbox is a new gadget that connects to your tv/TiVo and allows you via its software to watch your TV/TiVo on any computer via the internet. So, for example, I have the Slingbox connected to my TV/TiVo in the family room. I load the Slingbox software on my work computer, and can access both live TV at home, and anything on my TiVo at home. Obviously, in order to do that, the Slingbox needs to be connected to my home network for internet access. So, rather than run another 70 foot ethernet cable directly from the slingbox to the router in the home office (to which all the TiVos are connected), we added another router to the mix -- we connect both the TiVo and the Slingbox to the router at the TV/TiVo, and then have one 70 foot ethernet cord running out from that router to another router in the office (the one to which the other TiVos are connected). I would assume this is the problem, but does it really make sense that it works in one direction (i.e. transfers FROM the family room TiVO), but not in the other direction (i.e. transfers TO the family room TiVO)?

Petew, I saw your response after I finished typing. We will check. Does it make sense that this is only a one-way problem?

Are you using the WAN port of the offending router? If so, don't.
As petew said, use one of the standard Ethernet ports on the router, not the WAN port. Most routers have a built-in switch so there isn't any need to buy another. Just leave the WAN port empty and it will act like any other unmanaged switch.
You should also make sure the DHCP server is turned off on the second router.
