I have a Inspiron 5565, o/s Windows 10 64bit, that came with a Quailcom wireless card installed. I purchased the Intel AC 9260 to replace the horrible qc card. But the drivers that are listed on here aren't working. I need to get the wifi drivers that are compatible with my dell inspiron 5565 laptop. I first contacted dell and they told us that we had to contact you guys for the drivers since i did not purchase the card through them they would not help me and hung up. I have tried drivers from the dell website but could not find one compatible for my laptop. i also tried the newest updated drivers from intel website. thank you for your support.

You should have consulted with Dell prior to your purchase.
