Asus rt-ac66u, have I been hacked?

[Routernoob]

Hi, new user here! Not much experience with routers in general. I have an asus rt-ac66u router that has worked fine up until yesterday when I was suddenly unable to connect to my wifi with mobile/computers. When I looked at the router the power button is blinking fast as if the WPS is active which is new. The WAN LED was also blinking fast.

I tried restarting the router a couple of times with no success. I tried connecting to the router using an ethernet cable and typing in 192.168.1.1 but I couldn't get access to the GUI. I downloaded the latest firmware and firmware restoration tool and did a factory reset which made the power LED blink slowly. I was seemingly able to connect to the router and upload the firmware both via the firmware tool and via chrome. As soon as it was finished it began blinking fast again and I can't connect to the router.

Any ideas on what's causing this and what I can do? Have I been hacked via WPS?

Try to get the router into rescue mode and reflash firmware.

I did put it in rescue mode and upload the latest firmware but immediately after the problem came back

Check the power adapter first before going to the store to buy a new router...

rt-acn66u, probably had it for a while - the ac adapters are a weak spot...
