AC68U & AC88U networking issue

Hi Guys,

I'm new here and noob to networking so bear with me.

I have an AC88U as the main router and an AC68U setup as an Access Point. The AC88U is acting mainly as a wireless router, with just on ethernet cable connecting to the AC68U. Most my networking done through the AC68U as I have 3 ethernet cables connected to different equipment and at least 4-5 connections wirelessly. Everything was working fine for the past year until yesterday. I didn't have access to the internet on my PC and my server both are connected via ethernet. The strange thing is that the wifi on my phone was absolutely fine, I even did a speedtest and it was normal. Also my firestick which is connected wirelessly was fine. I tried to connect to the same network wirelessly from my laptop and I couldn't, I used the same laptop to connect wirelessly to the AC88U and it worked just fine. I can access the router's setup page through the ip address which shows that it is connected to the internet. I tried using a spare ethernet cable but didn't work. I even did a factory reset to the AC68U but still the same.

Appreciate any help in order to understand the issue here.

Thanks
Yas

Maybe the upper LAN ports 5 to 8 are failing on the AC88U... try connecting the AC68U to a lower port 1 to 4.

There are only 4 ports on both routers, I've tried a different port as well but still can't get a connection through LAN

could it be it's due to spamming?? if so, any idea how to find out and what should I do?
The AC88U does have 8 LAN ports. If yours has only 4 it is not an AC88U. AC86U maybe?

AS for the AC68U you may have better results by going back to Asus firmware. If your AP is, by chance, an AC86U I would use that as the main router and Merlin firmware would run OK on it. But my preference would still be Asus firmware.

I believe your router is actually an RT-AC3100 with incorrectly flashed RT-AC88U firmware (they're not compatible).

My bad, you are right. It's AC86U.
So I changed the Lan port again, then I went through the client list on the router and there were 3 clients that I couldn't recognize, i blocked them. After a restart everything returned to normal finally

thanks guys
