[dba-Tech] routers

Oh, here's another question -- if we use a wireless router, can we still use
cable to connect to systems that are close enough? Or, is it totally one or
the other?

You are going to be connecting Desktop systems or Laptops?  Do these systems
have wireless adapters already?  The laptops might or might not and the
desktops most certainly do not and will need one of those.
  With those you might want to match the brand of wireless adapter that goes
on the PC to the brand of wireless router so they are talking the same
variation. For example in my situation with the Linksys 54G with Speed
booster I would want to use the wireless adapter from Linksys that also has
the speedbooster tag.  I think that would be more important than matching
the router to the modem. In my opinion.
