@Vincent-TP I changed from PoE to 12V adapter. It crashed in 1-2 days same PoE. I decided return Shop for refund.

@Vincent-TP First start All clients work correctly. After 1-2 days Wireless clients can connect EAP773, but they can’t use internet. Other local devices work correctly. I can’t access EAP773 config...

@Vincent-TP Other devices on LAN working and can use internet perfectly, but EAP773 wasn't.

@Vincent-TP I connect all PoE+/++ devices with LINK Patch Cord CAT6 LSZH cables, NOT low grade cable. I tried to change CAT6 cable, waiting for result.

@Vincent-TP Do you plug the EAP773 into your main router? Or via a switch? Please give us the router and switch info. - via Zyxel L2 XS1930 switch. Next time when the issue occurs, please kindly...

I tried reset configuration. I'm waiting 2-3 days.
