Unfortunately, the Wifi on my notebook seems broken, as well as the hardware switch to turn it on, and I'm out of warranty so it's cheaper to buy external Wifi. I had an Intel 4965AGN chip which had great throughput(could reach higher than 60Mbit) and it was one of the few with true 5GHz wireless N support. My wireless mouse is on 2.4 GHz so I have set my router to 5GHz N, as setting it to 2.4 interferes with my mouse signal when the speed gets around 20Mbit. I have an Expresscard 54 slot on my notebook(I read that Expresscard 32 also fits in 54 slots) so I'm looking for a good WiFi Expresscard 54 or 32 with true 5GHz N support. I would also prefer one that can connect through win 7, without need for 3rd party software. Anyone knows a good one?
