i'd like to use a few of 254 cable connections on a private tv cable network to
link windows and mac computers for file sharing. i believe i need a cable modem
at each location and might be able to use vpn. there is already an internet feed
on the network along with television signals.

i know now to install vpn.
what kind of cable modems do i need?
will vpn work in this setting?
am i asking the right questions?

What do you mean by "private TV cable network?" Is it completely owned and
managed by you? Where does the TV and internet feed come from?

yes, it is owned and maintained by us. there is a commercial tv and internet
feed by a cable tv company. a dozen of the 254 sites each has a cable modem
supplied by the cable tv company. the cable modem is connected to a wireless
access point that we supply. each a/p is limited to five computers by
mac-address filtering.

The answer to this question depends on how close the sites are to one
another. If they are close enough to reach a single wireless router, you
could do everything you want with a single wireless network. This would
also allow you to reduce your internet connection to a single cable modem.
Of course, you'd have to evaluate if the bandwidth provided by a single
cable modem is sufficient for your needs.

terrain is not wireless friendly. steep hills and dense trees separate the
sites. am i correct that both a cable modem and a router is required at each
site?
