If you happen to use windows 7 ultimate and want to use swiftnetworks you might run into some installation hitches. On windows 7 ultimate, swift’s single user modem can not do a plug and play installation i.e. even if you have autorun enabled as an option. Try as you may it will not work, at least on my system it never did. So what I did was just to plug in a usb dongle and copy all the installation files from the Internet modem, run the files from the usb dongle and whala!! it worked.
P.S: The tech reps in swift networks office couldnt solve this simple problem.
