I have received two solutions for my issue of trying to upgrade to 5GZH wifi.
One - I cannot because I have an AMD A8-7050 Radeon R5 processor with 2 cores
Second - I can, using an HP COMPAQ 670292-001 INTEL 6235 WIRELESS N + BLUETOOTH DUAL BAND MINI Pci-E CARD
The more I research, the more I am in doubt of the second option. Can anybody provide a definitive answer. Thanks
