Hi, That's my (simple) question: What are WiFi cards N, MIMO (x3 antenna), MiniPCI Express I can put on Bios-modded (no whitelist) HP notebook (NC4400)? Many card on ebay are "not for HP/Lenovo/Dell", i've bought one of those card and it work. But there is many issues about power/energy management (take a look in precedent post : forums.mydigitallife.net/threads/28444-NC4400-Problem-with-modded-Bios )... Is possible tweaking cards? I'm looking especially for Intel and Atheros, or something work almost out of the box on Linux Backtrack (Monitoring, packet injection). I think that the question won't be simple to answer; link on ebay are welcome . see ya
