Hi all,

Since my ASUS RT-AC58U has started to intermittently 'drop' 5GHz (everything look like it's working, just nothing can connect via 5GHz without rebooting), so I decided to get an AXE75.

Got it all set up: hardwired via hub to PC, turned off WiFi, configured to use same SSIDs, added about 30 DHCP reservations and swapped it out... only the WAN port lights up orange and it won't 'talk' to the Internet. All active devices connected to the router... just no internet access, no 'smart' home.

From either a wired connection (50 foot CAT6 cable from Linux PC to router in bedroom) or via WiFi, I can connect to router and even the cable modem... just can't do anything further. Ping from PC or Router diagnostics times out.

I tried replacing the cable between the modem and router, no joy. Plugged the ASUS back in and it works fine, so it's NOT a cable issue.

Tried TP-Link Tether app, no joy - no internet. Tried to configure DDNS - no joy, no internet.

Day 2.

Thought long and hard - after reading a number of articles about TP-Link routers having issues with auto-negotiating port speed, I tried manually setting WAN port to 1000mbps - no joy, still orange, no internet.

Since I can't automatically update firmware without an Internet connection, I downloaded and updated the firmware from Archer AXE5400(USW)_V1_230718 to Archer AXE5400(USW)_V1_231115, no joy... and it wiped out all of my DHCP work.

Tried switching from Router to Access Point... still no joy.

I'd include some screenshots of my router settings, but I'm online with the ASUS, so not an option. I'd have to swap out routers, make the screenshots and swap the routers out again to send.

Please, I'm at my wits end. About to repackage the router and send back to Amazon!
