i recently got a wireless router(linksys) for my home, it worked fine with compaq laptop (new hence built in wifi) and my desktop. however i had to get TP link wifi device for my ancient sony laptop, i installed the drivers and everything it even shows that its connected to the wireless network. However the network kept disconnecting, so i played around with the settings a little and the internet started working(really slow), however the shared folders were still unaccessible from the sony laptop. Again tweaked the settings and now both internet/sharing does not work. Can any one point in the right direction wether these 2 devices are compatible or the correct settings. Sony laptop has Windows XP, SP-1 Networking worked fine when i use wired one.
