I have a Linksys wrt45g wireless router currently serving as the hub/gateway (is that the right term here) of my wireless network. However, I recently bought a newer linksys router that I will replace it with. I also have three TiVos in a room that have individual wireless clients. Since, most of the communication between the TiVos is either to the internet or between them when I trnasfer programs, I was thinking I'd like to replace the 3 wireless clients with the wrt45g acting as the client to the wireless network, but acting as a switch (or hub) between them. That way if I'm am transfering a program from one TiVo to another there won't be any wireless traffic. However, the wrt45g will not have a direct connection to the internet (as I don't have a cable modem in the TV room and don't want to install a 2nd cable modem (might not even be contractually permitted to without paying more). I also don't want to run a physical cable from the office with the cable modem to the TV room.
Is what I want to do, run the wrt45g as a client, easy to do? Does it require special software instead of the default install software? Can someone point me to instructions or suggestions?
