I am in the process of changing Internet providers and currently have no Internet at home. On weekdays, I can manage with using Internet only on the smartphone, but for the weekends, I'd like to have Internet on my desktop PC, which runs Ubuntu Maverick.
I have a 3G modem which uses a prepaid tarif, so I can pay for Internet use for a day when I need it. But it only works when the software for managing connections and balance is installed. So I have to use it on the Windows 7 laptop, I can't connect it to the Ubuntu desktop.
I usually don't connect the two PCs in a network. But if I do, is there a way to tether them (using an Ethernet cable - I must have a crossed one laying around, or through the old wireless router I used with the last provider) so the Ubuntu PC can access the Internet?
I'm not experienced with networks, so if you can point me to a good guide in addition to hinting at the steps needed, it would be great. I tried to google one, but all results are about tethering to phones.
