Using a computer as a router?

Is there any kind of USB device I could get that would plug into a computer and broadcast a WiFi signal?

yeah.... any WiFi adapter broadcast and receives signals... and can be used as a WAP.

Be more specific on the requirements....
So it would only plug into the computer which already has an internet connection, and broadcast its own wifi signal? Could you link me to a few adapters that would do this? I really don't know a lot about WiFi. Also, if I were to do this, would there be any way to tell via tracing through the ethernet port the computer is connected to that there is WiFi being broadcasted?

All WiFi adapters broadcast and receive WiFi signals. How that signal is used is a function of the computer.

What's the network topography?

Honestly I don't know. It is connected to an ethernet port that is on a connection spanned a large number of ports.

So another question, is there a way to have it set up so it would be possible to trace through the port and determine the computer is boradcasting a wireless signal? If so, would there be any way to determine beforehand if tracing through the port would be a possibility?

Alright, so if I were to get something like this, I could broadcast a wireless signal from my computer that other devices could connect to?
I'm not sure what you're trying to do. Turn a computer into an access point? Yes, you can do that. It's not for the faint of heart, though; you're better off just throwing DD-WRT on a router. No, you can't do it with Windows.
Not that it is the best solution, and not knowing what the OP is really trying to accomplish...

Does no one here remember "Internet Connection Sharing"... I know hardly anyone uses it, but it has been built into all versions of Windows since Win98SE.

Although ICS will allow WiFi connections to the Host DHCP computer, it will not allow port tracing.

A stand alone wireless router just seems to be more logical, and certainly safer than using ICS in Windows.
Ok nice. And with the wireless card I linked to, would it also be able to pick up and connect to other wireless internet signals for wireless internet access?

That isn't a possibility.

If you're using one wireless network card to act as a wireless-AP for an ad-hoc network, you can't use the same network card to connect to another wireless network for internet access.

You'll need a second wireless card or a hard-wire connection. Internet traffic is basically flowing from one network interface to the other.

But could it be used for broadcasting WiFi, and then if I so choose, switch into using it for connection to a WiFi network?

Yes, but not at the same time that it is using ICS as the Host Computer.
Normally with ICS, you will use 2 NICs. One for the internet (on the WAN side of the computer), and the ather as the access point (or wired on the LAN side).

You could... But Why? When you switch to using it to connect to a WiFi network, it cannot be used as the Access Point for your LAN. Also making the switch isn't as easy as just hitting an Icon on your desktop.

this program will easily make most wireless adapters broadcast wifi.

I have my desktop transmitting my lan connection as wifi in my dorm room right now with this program. Works great..

WIN7 only though.

I was going to say that. but seriously, it's a good program. using it right now on my netbook.

alternatively, you could buy a wireless router and set up the network that way rather than using a chain of quick-fixes

thanks!! Thia is sweet! Will it work in AP mode with the wireless card I linked to earlier in the thread?
