I have installed Ubuntu on a notebook that I have configured to connect to the internet using an Iburst USB modem. This works 100% after a bit of configuring.

I now have a desktop pc that I have installed ubuntu on, and would like to connect the two with a router. I bought a router with wifi, and would like to connect my notebook to the other computer using wifi, while still keeping the internet working with the usb modem.

The problem is that as soon as the wifi connect, the internet connection dies. Is there a way to force ubuntu to get internet access through the usb modem, but use wifi to connect to the network?

I am pretty new to ubuntu so any help would be appreciated.

I also have a samsung galaxy tab that I would like to connect to the internet through usb modem via the wifi, so is there also a way to share that internet connection with the other computers on the network?

Thanks in advance.....
