Question PCI-E Wireless card unable to detect

[ilovemuslim]

Hi tech support, Recently i had a computer which have an issue with networking. My wifi card ASUS PCE AC56 some time unable to detect from my motherboard (ASrock h170 pro 4). This issues usually happen very randomly. sometime i had to restart computer and the issue solved(this usually occurs when i first boot up my pc, then 2nd or 3rd restart my motherboard unable to detect), sometime i had to re-insert the wifi card to get it working(after re-inserting my wifi card, i did many restart attempt no issue at all).

When did this issue occurs?
This happen since early May this year(2019)

Did you try using another PCIe slot? Test in another computer? Contact ASUS support if card is in warranty? Check for newer drivers for the card?
