Hi,
I have 20 HP Compaq Presario CQ57 (CQ57-460EA) which currently only have a 2.4ghz wifi card.
I need to upgrade them to a 5Ghz wifi card. They currently have a 640926-001
We tried an Intel Dual Band Wireless-AC 7260 PCI Express Half Mini Card but they don't work. The BIOS just says "Wireless Module not supported, WLAN Module ID (702)"
Any ideas? How can I find out which devices work?
Thanks in advance for any help!
