I have a wireless router, a linksys wrt54g, connected to my cable
modem running my local lan, on the 2nd floor of my house, in a room
dedicated to being a home office. All is fine with that, I even get
reception out at the pool in the summertime using the variety of cards
and builtin wireless on the several laptops that my family and friends
and I have. The router also has 4 ethernet ports that I have
connected to various desktop and laptop units in the previously
mentioned office.

On the main floor of the house, I have two tivo units (in the same
room). One of this is connected to the network by a tivo usb to
wireless adapter. Now, I could connect the 2nd tivo to another usb to
wireless adapter.

However, I would like to consider buying something else to connect
said tivos to the network, since most of their network traffic will be
tivo-to-tivo or tivo to internet, and not tivo to pc, and I'd like to
minimize the traffic over the wireless.

I don't think there is a wireless router that has multiple usb ports.
Or is there? How about one with both usb and ethernet connections, so
I could plug a loptop into it and not use the laptops wireless card,
as well as serving the tivos. If not that, is there some kind of
router (a bridge perhaps) that will connect wirelessly and provoide
ehternet and then with usb-to-ethernet adapters allow me to plug the
several tivo units in? What kind of hardware should I be looking at,
and a rough idea of price (e.g. at best buy or cdw or somewhere else
someone might recommend)?

Thanks,
