I haven't read all your posts to see your situation incase it is
indeed a scattered description.
But I have never had any such issue with USB wireless adaptors.
They do the function of wireless NICS.
So they connect to the router-modem. Wireless USB adaptors get their
IP from there.
Not like USB modems
That's my experience of them anyway.
I have had set machines up for people before, with some connected with
a cable, others with wireless usb adaptors, no problems. Each device,
the wired NIC or wireless adaptor, gets an IP from the NAT router.
Now for some speculation.. and blatant blabbering.
I don't know if you have a USB modem.. In which case.. I vaguely
recall that sometimes or often they only allow one computer anyway.
They send one public IP.(via DHCP I suppose) to any devices e.g. wired
NICs. Or I suppose wireless usb adaptors. Speedtouch make such a
common usb modem I think, and I think people call it a half bridge
(something along the lines of it not doing routing!). That particular
one I heard of didn't have a wireless feature i.e. wouldn't see
wireless adaptors at all. But it is possible in theory for tere to be
a usb modem like that that is wireless and only takes one comp. |

Yes, it's a wireless modem I suppose -- that's where it fits in the
architecture anyhow. It lets its host connect to the Internet, and I was
hoping it would also allow a client on the network to leverage the
connection, but it will not. I get a report that two computers are using the
same IP address, and that's illegal.

the issue then, is not to do with it being wireless.
It's the fact that it is not doing NAT.
Cable modems (I have seen NTL cable modems, so talk from that
experience. like the NTL 250). It had 2 sockets, one for USB network
connection, one for Ethernet. You could only connect one computer to
it. Because it had the one IP.
I imagine that if one took a switch and connected it to it, then it
would still have that problem.
I have heard that on NAT Router/Modems. Where one can turn off NAT,
aka just tell it to act as a "switch/bridge" - it will do the modem
function too anyway. And then you login through windows (as one does
with a USB DSL "half bridge" modem e.g. speedtouch 330
http://en.wikipedia.org/wiki/SpeedTouch_330 ).
You'd probably get the same effect doing that. Only one computer able
to connect.
Infact, if one took a speedtouch 330 (wired usb modem, and added a
wireless access point, you'd probably get the same effect too - a
wireless usb modem, of the half bridge kind).
Now.. So, your problem is equal to the (no doubt commonly asked)
problem, of how to connect 2 computers to a cable modem.
(I could have said "to a usb dsl modem" or something, but anyhow. I
figured cable modem was very common and end users would ask in those
terms too, and get answers)
I found 2 results on that.
I have hardly researched it, only checked the first 2 links on it.
One essentially says get a NAT Router. (that will hand out different
IPs, one to each comp)
The other says use ICS. It involves putting 2 NICs in one computer(or
rather, having 2 NIs on it), connecting one to the USB modem, and one
to the other computer. . ICS uses NAT, so it will make sure the comp -
itself and the other one, have different IPs.
So that's that solved. Be interesting to know of any other solutions..
A point regarding dangers of a so-called direct conneciton and
benefits of a NAT Router. (the so-called "direct connection" is so-
called because it is more direct since it means no NAT Router. Just
computer to modem -Cable modem or DSL modem. Or computer has PCI DSL
Modem Or PCI Cable Modem - they do exist it seems!)
I haven't used ICS before.. But certainly in the case of a NAT Router,
it's actually typically more secure than a direct connection. .OR
rather...
A (colloqial-) "direct connection" to the internet, is typically
insecure.
Because if your machine gets hijacked e.g. you browse to a malicious
site and get a malicious server(a trojan) running. Then there is
nothing stopping harry the hacker from connecting to it(messing more
with your computer, or using your computer to attack e.g. spam
people). Whereas with a NAT Router, at least harry the hacker would
have to get past the NAT Router somehow.
The windows firewall would stop harry too, and would be fine, But, the
reality is that if you ran as administrative, (which one prob did to
get damaged through a browser hijack anyway), and if administrative,
that malicious software could bring down or make an exception in your
windows firewall. They often disable the windows firewall, it's a
common target. Really the computer is compromised in this situation..
So it's not really the windows firewalls fault. But in practice, NAT
Routers are very helpful in providing some better security, than a so-
called direct connection. |

correction.
with a USB modem, the usb port is I think an NI - network interface.
So with ICS, you'd only need one additional NI. (most motherboards for
years now have had an NI built in).
So you won't even need anything new to do this (though it's always
good to have NICs around, as it is working spares of any/every
component or software). |
