Thank you for helping!

The router is wired to the server with a usb cable and all of the laptops connect to the router via wiresless. The router is connected to the modem with a usb cable.

Although this doesn't makes sense the more I think about it. When the internet would go do down. The laptops would not connect with the server.

I made a note that the wired ip address to the server was .25, but the wireless IP address to the server was .210. I made a note to myself that I discovered that if the internet went down, and if I switched the connection on the server to the wireless connection, and if everyone's laptop was connected wirelessly, that the internal network would work. I then think that I "bridged" something so that the internal network would work regardess whether the server was connected with a usb or wirelessly.

Right now I can turn the internet modem off and everything works great (the server is plugged in and the laptops are wireless). I'm just trying to figure out what I did from an educational standpoint.

Does this make any sense? Again, I really appreciate that you have the patience to hear such a half baked story.

   "connect to it" _how_? What, exactly, is connected to what, exactly?

   "connect to the server" _how_?

   "couldn't" is not a useful problem description. It does not say what
you did. It does not say what happened when you did it. As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

   With my weak psychic powers, I have no idea. I don't know why you'd
need to do anything. An Internet connection is not required to have a
functional LAN.

     By "usb cable" you actually mean "Ethernet cable"?

     That's a modem+router in one package. What, exactly, is your "the
  modem"? What, exactly, is your "The router"? What, exactly, is
  connected to what, exactly? (Hint: If a device has different types of
  ports, then "connected to device" is not enough detail.)
  
     If you actually have a C7000, and its router section is still active,
  and it's connected to some _other_ router, then you'd seem to be
  cascading multiple routers, which could cause multiple problems.

     Treating that as one sentence, ...
  
     "connect" _how_?
  
     If "the internet would go do down" because of a problem with the
  router (whatever it might be), then any traffic through that
  (unspecified) router might be affected.

     Don't abbreviate IP addresses, unless everyone knows what you're
  omitting. If you actually have cascaded two routers, then the hidden
  parts of those addresses could be significant.
  
     A computer/device, strictly speaking, does not have an IP address; a
  network _interface_ can have an IP address. If your (unspecified) "the
  server" has two network interfaces, then each one could (probably
  should) have its own IP address. If the omitted parts of those
  (partial) addresses are the same, then I'd expect problems if both were
  active at the same time. And if the omitted parts of those (partial)
  addresses are different, then I'd expect _different_ problems.

     I don't know what that means. What, exactly, did you change where?

     I think that you don't know enough to judge why any of what's
  happening is happening. You haven't described what you did, or what
  happened when you did it, clearly enough for me to conclude anything.
  
     Currently, I know less than I thought that I did about your
  (unspecified) "the modem" and your new (unspecified) "The router".

     I can't tell you what you did. I expect you to tell _me_ what you
  did, and what happened when you did it. And what you have. And how
  it's all connected.

     Less all the time.

     It's about exhausted. Put your story back into the oven, and come
  back with a more complete and coherent description of everything?
