Hi and thanks for all this help.

I'm using the lastest version of router firmware also asus app.

I've noticed it when the kids have been downloading on there devices on wifi, via there xbox ones pc or mobiles, I can still download on other devices also browse the web all fine untill I try to access the asus web ui or asus app. Soon as the downloads decrease the web ui responds. When this is happening, the web UI can load but it's very very slow, and incorrect info is showen and the asus app times out.

Connecting via lan, I've not- havent tried will do that later.
There is no errors in the sys log.

I've also notice when there downloading via wifi it's only 25- 30mb, which is not my limit, they should hit 54mb speeds when downloading like if I was via lan?
Also there connected via 5ghz.
Ive notice it on there xbox ones, as there always on them, if I limit the bandwith of the wifi devices Its fine.

Just tried downloading on 2.5ghz, downloading at 50mbps, and the web ui problem is not there. Seems to be 5ghz related.

My wifi-5g settings.


A update on the LAN, I can connect fine. so its only when downloading with the 5g and then trying to access the UI or app via 5g.

This has been happening for some time, in older Firmwares too, so logs ive sent in the past should show too, you know my email, the mac address of the d/l is starting 28:16:A8, and the device access UI is 44:91:60.

I can do as requested above but will take some time to do so, week or two now.

Also I've tried changing some wifi settings see image.

And notice it likes the higher range see pictures

I will be sending a log in soon about the above. but wanted to add that some devices also seem to lose wifi siginal for no reason even when I'm close to the router. As you can see by the log below. I've hidden a bit of the mac address.
