hello, i have the same card
i cant force to work it under window 8.1
but it work in windows 10 tech preview(after updating drivers) but works realy sloooow i have only 1mb/s but maybe it is because preview
you notebook have only one mPCIe slot? or whatever you use
our card use usb for bluetooth
mPCIe not always have usb line on it (but it might be in other slot)
Thank you very much for the reply!
I have also installed the wireless card in three other ancient laptops, Dell Precision M4400, Lenovo Thinkpad X61 and T61 under windows 7 SP1. All worked with 150 Mb/s connection, because my router was a 'N' router. Therefore the intel 7260 card could function normally under windows 7. Importantly, the wireless card worked fine after each re-start in Dell Precision M6300, although it only lasted three minutes. I tried to stop all other programs, but it did not change anything.
For bluetooth, I agree with you that the M6300 might not have USB in its m-PCI-E slot.
I think the wireless adapters should be fine. I bought five adapters from tigerdirect. Two of them worded fine on Thinkpad T61 and X61. The rest of them can not work on Dell M6300.
I did not check with Dell custom service about Dell M6300. However when I installed the 7260 adapter on Dell M4400, it did not work until the newly updated driver came out.
