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 ?

Do I require a special configuration on the wireless router?
In other words, if I was setting it up for a home network, I would
enable DHCP server. Would I disable this for our scenario?
Are there any others to be aware of?
Thank you in advance.


I assume you have DCHP running on the DC now ? If so then just disable
DHCP on the AP. I usually use all static in my setups. Get the wireless
up and running as it is out of the box...no encryption, etc. Then after
you are satisfied that it works, enable encryption, and authentication.
You can choke down acces by MAC address, allowing only your PC's MAC's
access. While this MAY have an affect on performance, depending on how
cheap a router you have, and everyone will say a MAC filter is easy to
get by, if there is (virtually) no performance hit, it will stop CASUAL
users...neighbors that run across an open AP.
