RT-AX88U Pro Dropping WAN Connection

[dcmonroe00]

I recently updated the firmware on my Asus RT-AX88U Pro to 3004.388.8_2. The router was working fine prior to the update, but immediately afterward, the WAN connection became unstable. It drops every few minutes, sometimes for just a couple of seconds, other times as long a minute. The LAN connection is fine, but internet drops. I tried reverting to version 3004_388.7_0, but that did not fix the connection problem. I've confirmed that the router is the issue by connecting a computer directly to my Netgear Nighthawk CM2050V modem, and the connection was fine, but when the router was put back in place the instability started again. Any suggestions would be greatly appreciated!

Log into the router and go to System Log > General Log to see why the connection is dropping.

Thanks for the response. I've looked at the log, and I'm not seeing any events that show a connection failure. However, I am running Net Uptime Monitor, and it is failing every few minutes, and activity keeps pausing every few minutes. As noted in the JPEG, I've had 24 failures in 56 minutes.

If there's nothing in the log that suggests the problem is upstream of the router. I know you said that the problem didn't happen when you plugged your PC into the modem so it maybe some sort of provisioning issue on the ISP side.

I suggest you log into the router using the PC that you previously connected to the modem. Then go to WAN - Internet Connection > Special Requirement from ISP. Click on the MAC Clone button which should populate the MAC Address field with that of your PC. Apply that change and wait a couple of minutes. Then power off the modem and the router. Wait a minute and turn on the modem. Wait another couple of minutes the allow the modem to fully boot up before turning the router back on.
