Hi. I am having a problem that has already been discussed here but I am still having trouble. I have a Toshiba Sat A70 laptop which came with a windows disk.I was advised to re-install windows on its own from a different disk.OS runs much faster now but have the unkown device with the question mark next to the Ethernet Controller.It appears when I insert my Netcomm NP534 wireless PC Card.Went to Netcomm and downloaded a zip file which was supposed to be a Driver but there was no exe file in it.Just a bunch of .bin files and an .inf. When I update the ethernet driver and try to direct it to the .inf file, it says its no good. What do I do with these files? What do I do full stop? I know this question must be getting a bit old for you.
