Okay, I'll keep troubleshooting. I realized that the WebUI is super laggy compared to 384 which I just reverted back to. Everything is working as expected on 384. I'll try upgrading to 386 again and factory reset.
I upgraded my AX88U to 386.2_6 from 386.2_4 and did a full factory reset but since the upgrade the LAN ports stopped working until I enabled Bonding/ Link aggregation which I didn't have enabled before. Also, my USB HDD that was working fine before keeps going online then offline.
I'm having this same issue since the update. None of my devices that are wired in are able to get an IP but wireless is working fine. I've been going in circles rebooting my switches. I did a factory reset after I updated the firmware as well.
