I got a wrt54g hooked up to a directional antenna.the directional antenna is only hooked up to one side of the router the other side is the small rubber antenna. 300 ft away I got a dlink dwl-g810 on the other pc hooked up to a directional antenna . it works ok I can do everything . but when I enable my wireless b on my laptop where the linksys is.... it kicks the other pc off.the dlink is g and the laptop is b. the flashes are current.how can I make it so I can surf on both pc's at once??????? without getting kicked off.
