Ok. So I built my own PC, and it runs fine. It does not have a PCI Express Wifi card. To connect it to the internet I have been sharing my Macbook Pro's wifi signal over ethernet. That is a hassle, because I like to take my laptop with me when I leave, plus it is not very fast. Upstairs I have an Arris DG860 modem with a Netgear WNR1000 v3 (N150). I have an old Belkin F9K1001V4 (also N150) laying around, and I was wondering if it was possible to use the Belkin as a bridge, so that it would get the wifi signal from the Netgear router and output it as ethernet to my PC. Any help is greatly appreciated.
