I have tested with a old antenna I have which is only for 2.4ghz WiFi its really old and crappy and its being used on something else but it works so I know the motherboard is completely fine. But when I connect the Asus WiFi antenna that came with the motherboard it doesn't work at all.
Any advice? No point sending the entire motherboard back and having to disassemble my entire system just for a accessory.
Hoping I can get a replacement or buy a new one if I have too.
