Thank you for this information @xyzbird! I am finally sick of the endless ping spikes with the Realtek 8822be module, so I decided to go ahead and order the AC 9260NGW too, based of the information you gave.
Do I need to replace the realtek module or can I just use the 2nd M.2 slot on the back of the motherboard to install it?
And what do you mean by "the CMOS 2032 battery was down on volts so that got changed"?
Thanks for your help!
