I have a Toshiba Satellite L455. I swapped out my old Network Adapter for an Intel 4965AGN Network Adapter. The drivers updated perfectly fine. The device manager says it functioning properly, but when it is enabled it just says "Not Connected". When I run the diagnostics, it says that I need to turn my wireless on. It is true that my wireless does not appear to be on, but when I press FN+F8, nothing happens. When I swap the old adapter in, the wifi is on automatically. I guess I should mention that there are only 2 antenna wires in the laptop, but 3 connecters on the adapter. I've read that doesn't matter. I've also tried switching the wires around, but that doesn't seem to help.
I am completely lost and would appreciate some help. thanks!
you cannot just switch the network cards in a laptop due to different PIN out of the network card. Also your motherboard will not recognize the NIC right and therefore the Fn+F8 will not work properly.
the only save way to upgrade the wireless nic is using a USB wireless nic
