where you don't need a router or another modem. Just buy two wireless cards and set up ICS (internet connection sharing) and you can use the internet on both machines at the same time with just one connection and have the benefit of the network as well. Only downside is that the host pc needs to be on to access the net.
<However, I CAN connect to my single Tiscali account using the desktop through one phone socket and the laptop through another phone socket but NOT at the same time.> That is correct, but you will need to close the other computer down as BB is permenant connection until you close it, so you wont get on line with the second comp if the first not completely off line. But that may be no trouble to you. I found that it was a pain so I networked my two with a cross over cable and apart from the main comp being on all of the day( I only switch off when I go to bed anyway) it works no bother.
