@Dr_pepper Change the channel width on 5Ghz to 20/40/80. Don't use 160 mhz since it overlaps with DFS channels. DFS channels share weather and airplane radar bandwidth so it shuts 5Ghz off if it detects radar being used. If you live in a flight path, the problem might be more major. The factory default is 20/40/80/160 so that's probably why a reset didn't fix your problem.

@Kevin_Z Only issue that I've found is that the app and website present an error if trying to modify the LED on the router. Not an issue for me, but it maybe for others.

@TheSassyBear Thank you for your feedback.
Could you please provide an error screenshot when you try to modify the LED Control settings either via the Tether App or Web UI?
Is this issue reproducible or does it occur occasionally?

@Kevin_Z I think I know why I was loosing connection on my S25 Ultra. After getting the "connected without internet" error I tried connecting to 6G and 2.4 and they both got stuck on "obtaining IP address" I turned DoH off in the router setting and the issue was resolved. I think there's some kind of incompatibility between the S25 and DoH functionality because other devices on my network worked fine. Andriod phones have a function called "private DNS" which allows you to input a DoH address. I had mine set to automatic at the time.

I see the US version Firmware 1.2.1 is officially launched/downloadable on the support page (https://www.tp-link.com/us/support/download/archer-be800/v1/#Firmware) since today, will the EU version also be released today? (Or can EU users use the Firmware of the US support page to download?)

@qazwsxedc16 Thank you very much for the update and I'm glad to hear that the Samsung S25 Ultra works fine with the BE800 now.
I will report this issue to the team and ask them to check if there is any incompatibility between the S25 Ultra and DoH on the BE800.
