RT-AX88U not connecting to upgrade server or Asuscomm DDNS

[bwj]

After the last UK storm I found I was getting a lot of internet dropouts so factory reset the router RT-AX88U, upgraded to the latest firmware, and reinstalled my settings.

[I'm on EE full fibre and the connection settings have worked solidly for the last two years, and before that the same settings worked on BT]

Since the upgrade I've had a weird problem that

1 - no browser on any device in my network can connect to any Asus website, except from behind a VPN
2 - ipv6 settings seem correct but there is no ipv6 connectivity
3 - router does not connect to Asuscomm DDNS and says that there has been an "unauthorised registration attempt" for my DDNS username at Asuscomm
4 - router cannot connect to the Asus upgrade server

After experimenting with these WAN DNS settings all of which had previously been set to "NO", problems 1 and 2 resolved and connections to Asus websites and ipv6 connectivity now work. I'm not sure which setting now on "YES" is responsible or might be causing other problems!

Problems 3 and 4 persist so still can't connect in the router GUI to the upgrade server or DDNS. I've switched for the time being to NO-IP DDNS which works fine but it is a pain to reset other devices

I have also switched to the latest Merlin fimware, with essentially the same settings, but the problem persists. Any help appreciated!

Hi, the Rt-ax88u router has a lot of issues with the latest updates. I had above issue also, no way to get ddns at work, also wifi falling down (I asume the radio deivers are corrupted because my wifiscanner metioned "epigram" als "manufactured by" in stead of asustec. Also mac address away from wan port when I want to use this router as an aimesh node. No way to connect.

I replaced this router with a be92u icm with my old aimesh node ac68u which works perfectly.

I assume that asua working at a huge patch for this router. I am awaiting for that.

Goodluck
