WWAN Bridging Help Please

[meetm]

Hello...

I have a Sierrawireless 555
http://www.sierrawireless.com/ProductsOrdering/AC5551xRTT.asp and have
internet access through this card, I want to be able to use the LAN
connection (RJ45) on my laptop to let my friend connect to the internet
throught my laptop when I visit. Her PC has a network card in it but isn't
connected to a network or doesn't have a modem for internent access, she can
only use it for software programs and games, etc.

Thanks for your help.

Hi, meetm
You could install Internet Connection Sharing (see MS Help on your computer
about this, ICS), but there is no need to do that because then you're
computer would have to be running for the other computer to use the net.
Your wireless router probably also has at least one jack to connect physical
cable to, and that could go into a "hub" to expand how many can connect to
it that way, so just run the cable from the existing NIC to the router that
way (or replace the NIC with a wieless one or just add a wireless NIC if you
have an extra slot).

Hi WinGuy,

You are right about Meetm being able to use Internet Connection Sharing. The other part about the router is not applicable. The
Sierra AirCard is a cellular connection. It plugs into a PCMCIA slot and in his case uses the CDMA network.

I use a Sierra AirCard 750, and it is GSM/GPRS cellular. It only get speeds between 36Kbps & 60Kbps. It is about as fast as a
dial-up connection, which means if you share it, your throughput is going to be atrocious.

Hi, C.Joseph Drayton
Then how is the other computer supposed to get assigned a valid address that
can be seen on the internet? That's the purpose of the router, as you
probably know the router gets the internet visible address from the ISP, and
does the necessary translation of the various router assigned LAN addresses
to that one internet visible address. ICS basically does the same in
practice. The software you are using may be hard coded to use their own
physical device and thereby not be sharable nor usable with ICS, but I'm not
sure on that. Basically, it seems to me that you're trying to loop ICS
through that specialized software and it might not be designed to work that
way via ICS. Your problem doesn't sound to me, now, to be Windows related
per se and I'm suspecting you need a solution from that 3rd party
manufacture (they might have some equivalent of ICS to work with their
product).

Hi WinGuy,

If I am understanding your question, the answer is that ICS acts as a 'gateway' to the Internet. I don't KNOW how ICS works, but
in the case of my Sierra AirCard 750 it does work.

The AirCard is treated like a network connection. The AirCard is assigned an IP when it initially connects (address is dynamic
(ie. changes with each connection)).

I tried it last night, after I saw the original message in this thread, and it took all of about 15 minutes to set up where my
girlfriends desktop was the guest and my laptop using the AirCard was the Host.

One thing to note, is that with my AirCard or the OP's AirCard, they are an always on connection unlike a dial-up connection.

Hi, C.Joseph Drayton
Ok that rules out a potential propriatary issue, then. Perhaps you could
tell meetm how you set things up? Did you use 2 NIC's by any chance, with
the host having been assigned a static LAN address for use as a gateway
address and one being the AirCard itself and both on the same host machine,
the wired one on the host connecting to the wired NIC on the guest machine?
Just curious how you did it. I'll bow out of the topic and just watch since
you've found a way that might be of help to meetm.

Hi WinGuy,

All I did was disconnect my Cable modem from my network. Then I ran ICS and away it went. I didn't do a lot of playing with it
since as I said, I have a cable broadband setup. I just wanted to see if ICS would work.

Aha ... an idea, then, is that the connection for the device needs to be
right-clicked and made the default one, because maybe it's trying to use a
different existing default connection. Worth a shot, I guess.
