I have a Linksys wireless router... Dell desktop, a Toshiba laptop and a Lenovo Thinkpad laptop at home. We are always on the internet on all 3 computers ..the desktop and Toshiba laptop work fine but on the Thinkpad the internet is constantly disconnecting and reconnecting and it's very annoying ..it's obviously not the Linksys..It can't be the range I always have both my laptops next to each other when I go online. can anyone please tell me what is the problem?? I set my Linksys mixed wireless b and g. Should I just set it to either or??
