Hi @damager82 ,

Could I confirm that you have tested both wired and wireless connections and still cannot use Archer AX55's network to run World Of Tanks, right?

Please recall whether you have set up a static IP for PC? Or did you need to enable port forwarding before?

I suggest you try to enable upnp: How to make Xbox online games run smoothly by UPnP (new logo).

Please test whether World Of Tanks can run normally under the guest network?

Please test whether you can play the game normally on different PCs? This step is to confirm whether a specific device, a specific website, or a specific platform cannot use the AX55 network?

Hi, thanks for answer
 

To have clear testing I did next steps:
1) Restore all configuration settings to default values, except your login and cloud account information.
2) Make start wizard config: TimeZone, WiFi name/pass, ...
3) Internet Connection Type: Dynamic IP (auto-detected)
4) Security > Firewall > Disable SPI Firewall
5) Network > Internet > set Primary DNS = 8.8.8.8
6) Create guest WiFi

7) UPnP is Enabled by default, I didn't touch it
And actually I see clients there, when I start qBittorrent:
NAT-PMP 54714 tcp | 192.168.0.183 | 54714 | 54714 | TCP
NAT-PMP 54714 udp | 192.168.0.183 | 54714 | 54714 | UDP
But all my torrents are in Stalled status

In Tanks I see message:
Cannot load config file. Check you connection.

In Discord I see statuses:
RTC Connecting/No Route

Web-sites, Youtube, Netflix work as usual.

I checked all these things on LAN, on WiFi and on guest WiFi, on 2 desktop computers.

If I just replace TpLink router with my previous router, everything works fine without any issues.
It probably means that my Internet Provider and my computers are fine. And issue is somewhere in the TpLink router.

Hi  @damager82,

Please enable IPv6 and select Pass-through(bridge) referring to the FAQ: How to set up an IPv6 Internet connection on the TP-Link Wi-Fi Routers

After confirming that the save is successful, you can restart the router. Then test whether the three platforms can be used, and check whether there is different information displayed under UPnP?

  @Joseph-TP 

I enabled IPV6, saved and did reboot.
Result is the same: broken discord, torrent and tanks.

UPnP table is the same as well
