Complex home networking question?

Question

I have a laptop that is on loan from work. It has a wireless G card in it, but I don't have a wireless access point. I do, however, have an extra wireless-G usb adaptor. Now, here's what I want to do.

I have a wired router w/ an IP of 192.168.1.1, I also have an extra PC which is also on the wired network. I would like to connect the wireless USB adaptor to the extra PC. I would then like to connect the two wireless cards through an ad-hoc connection and be able to browse the internet on the laptop through the extra PC.

Like this

Laptop
|
|Wireless
|
PC---wired---router-->Internet

The only problem with this, I think, is that the Windows intenet connection sharing would end up competing with the config from my router. So I think I have to manually configure the TCP/IP settings (IP, SNM, Gateway, DNS, etc.)

If the PC has an IP of 192.168.1.110 wired and 192.168.1.210 wireless and the LT has 192.168.1.220 wireless, what would I enter into all the fields to get functionality

Answer 1

Buck, you are incorrect. A USB adapter transmits data in both directions.

To the OP, you will need to enable internet sharing on your Windows PC on the router connection. You will then need to create an adhoc connection to your notebook via wireles and then bridge the LAN and wireless connection on the desktop. It is complicated but there is plenty of help online.

(Take heart, it can be done, I have done it myself while my wireless router was out of action)

Answer 2

am i missing something here ? are the usb adapters recivers only . if so it's not going to work wireless because nothing is transmitting a signal , what your attempting to do can be done WIRED using the pc nic card and a private ip in the tcpip settings with a cross over cable

Answer 3

you don't need to change any of the ip's, what you do need to do is setup the usb adapter as an access point rather than a connection...then setup to share the connection, then with the laptop you scan for networks and it should find the pc with the usb adapter....and voila......although most usb adapters are just antennaes and the programs they come with are just for connecting to a wireless network and you don't have one....this probably won't work.
