To rule out the obvious, have you disabled SmartBOOST fully/DPI/BI at all?

I know OperaGX has a built in Adblocker, disable that and also make sure you're accessing via HTTP instead of HTTPS and try again please

No but it has been requested before so may come in the future

Added - it has been removed temporarily

By recently do you mean you haven't used it for awhile and then upgraded? If so it may have been a big jump in firmware, did you do a factory reset after the upgrade? What browser/device are you using to access?

That's very bizarre, could you provide a screenshot of the WiFi page please? If you disable the Geo-Filter do you still get kicked?

It's likely it auto upgraded you, try this one.

For eFootball switch to custom, cover Japan, then cover the servers you want to play on, restart the game and see if it works better then.

What game are you playing? Can you provide a screenshot of the entire page showing what you see when you get a game outside your radius please?

Don't use the bookmark to access it, you may have inadvertently bookmarked the setup URL which could explain why you think it's resetting frequently. Use http://192.168.77.1 directly instead. What is the model of the modem/router the R2 is connected to and how have you set that to ensure all traffic flows to the R2? E.g R2 in its DMZ, modem/bridge mode In DHCP Settings on the router set static/reserved IP addresses for devices and also extend the DHCP lease time and see if that improves it.

Reboot, wait 4 minutes then update and it should work then

Are you running the speed test/ping optimizer tests when the connection disconnects? I can see the wizard was done but nothing to indicate it did a reset, have you bookmarked the interface is that how you're accessing it?

Disable Geo-Latency and Ping Assist in the Geo-Filter menu then reboot the game and try again. If you make changes to the Geo-Filter on the game you will need to restart the game before matchmaking

Reboot the router from the interface, close the tab/interface, wait 4 minutes then try accessing again, does it load correctly then?

None of those files are the configuration file as far as I can tell, are you sure it can be used with the router and it's not just PC only?
