I have been through the wringer many times when it comes to UPGRADING laptop WiFi cards. HP was the worst. I hate to have to modify the BIOS . I am wanting to replace my current 802.11 AC card with an 802.11 AXC card. I have a cheap Ebay wifi dongle that is 50% faster than my factory ASUS card. That is disgusting. I am wondering if anyone else has pursued this course of action. Any information would help.
