The computer I am using right now is windows xp sp2. The only way for me to access the internet is to connect directly to this computer. I have the linksys wireless-g 2.4ghz 802.11g with speedbooster broadband router. If i connect this computer to the router and try to get internet access I cannot. There are 3 other computers in the house that need internet also. One of them is a desktop with xp sp1 which I instaled the pci adapter into. The other two computers are laptops with wireless network cards already in them. The one laptop is xp sp1 the other is xp sp2. All of the computers used to be able to connect to the internet, but earlier today I was messing with one of the laptops and that laptop couldn't connect to the internet anymore. Then I messed with the main desktop which is directly connected to the internet to try to fix the laptop problem, only to ruin the network for all the computers. I need help.
