i am about to buy a laptop that has built in 802.11g. i want to share my cable internet connection with the laptop and the computer and want to do it in the cheapest way possible. i have noticed that equipment for 802.11b is cheaper than stuff for 802.11g(the router and the cards,btw how good are the usb adapters for this purpose?) if i got a 802.11b adapter for my comptuer and a 802.11b router, would it work with the laptop that has 802.11g built in to it? i was looking at 802.11b because it is cheaper and i do not really need the extra speed, all i will do is internet connection sharing and the occasional file sharing between the two.
