Here is my scenario:

We have a network of 10 computers and a server all connected to a
switch using ethernet.
The current connection to the Internet is 64k ISDN.
Cable modem and DSL are not available at this location.64K....ouch!







I found a reasonably priced 'wireless' network provider and a
signal is available.
I would like to connect the output of this modem to the input of a
wireless router.
The next step would be to add USB based wireless adapters to some
of the workstations so that they can obtain faster access to the
Internet. In other words, 10 computers and the servers would be one
network and maybe 6 of the 10 would be wireless on another. These
wireless connections would only need to share the Internet
connection but not printers or other resources within their
network.

Is it possible to configure Internet Explorer on just these 6
computers to use the wireless connection (and not the wired) to
access the Internet. The other 4 computers would still use the
wired connection thru the switch? How would I accomplish this?I
don't know the purpose of having the wireless on some workstations.
Wireless is ALWAYS slower than wired, especially when you have more
than one wireless client on an access point. Why spend the money on
the USB devices ?

How is the ISDN line connected now ? To the switch ? With a router ?
These servers, are they domain controller, or just file servers with
mapped drives ?

The short answer (not knowing your full network configuration)is all
you would need to do is connect the new WISP device to the switch,
and then change the default gateway on the machines you want to use
the WISP to the IP of the WISP device. It can be on the same network
as everything else.

It's all in the default gateway setting.

The output of the ISDN modem is the input to a hub. One of outputs of
the hub is input to a PC (required because of an applcation) and the
other is input to a SBS server (domain controller). The other NIC in
the server is input to a 24 port switch.
The reason for the USB wireless is because I did not think that the
switch could have 2 input Internet connections at dissimiliar speeds
(64k ISDN and 3 Mb wireless).


I'm not familiar with ISDN at all. ISDN never went over the way they
thought it was going to.

Now, from what I gather from your description, the Domain Controller is
between the 'rest' of the network and the ISDN access device ?

ISDN ---> HUB ---> Server ---> 24 Port Switch

Then the hub has another PC on it, and the rest of the PC's are connected
to the switch. The server is configured to do some type of NAT ? The PC's
have the server IP as it's default gateway/DNS ? Is the DC doing
firewalling/access control and/or proxy server as well ?

That is the biggest issue. If the DC is providing those functions, then
it is more difficult to do the setup.

Yes, you can have more than one internet connection available on a
switch. You can have 4 DSL/Cable modems w/4 routers. You can uplink the
LAN side on each router into the same switch. As long as the LAN
interface on each of those 4 routers is on the same subnet, and not
identical, like 192.168.1.1, .2, .3, .4, any PC on that subnet hooked
into that switch can use any of those connections. All it would take is
to change the default gateway to the specific router/cable modem you
wanted to use.

With your situation it really depens on what you are/want to do with the
DC. Setting the DC aside, the WISP device's router's LAN port can be set
to the same subnet as the rest of the LAN, and uplinked into the switch.
Then you can just change the gateway of whatever PC's to the IP of the
WISP router. But doing it that way would bypass any control your DC has
on the network. Of course, I just realized that is what you were looking
at doing anyway with the wireless cards.

Is the wireless Clearwire ?
