Would like to share my experience Dell XPS 9100. I tried 3 different combo cards finding a winner on 3rd try. All of these cards have excellent WIFI connection to my latest model Apple router! Bluetooth was the issue on both the first 2 cards tried:
#1: Gigabyte Bluetooth 4.0/WiFi Expansion Card GC-WB867D-I
#2:Intel 7260 IEEE 802.11ac PCI Express Bluetooth 4.0 - Wi-Fi/Bluetooth Combo Adapter for Desktop
#3WINNER: MP2W-6235 (PCI-e Desktop adapter with Intel Centrino Advanced-N 6235)
Bluetooth connection for my Targus Soft Touch Mouse was sporadic and sometimes not at all with the Gigabyte and also 7260! Maybe I just didn't have the proper/latest drivers not sure? Now that I have the 6235 My Targus Bluetooth Mouse shows a very stable connection all the time! Bought the last one available from Amazon but I believe it is still available from M-Mactors!
