I have a GL-BE9300 router using the Beta firmware (4.8.99). There router is ok, but i am having lots of issues with Wi-Fi clients disconnecting and some clients being connected but the internet not working. Also, many clients in the list are coming up as unknown which is odd and was not occurring with my old router.
Regarding Clients showing as “Unknown”:
Please check whether the device has a randomized/private MAC address enabled. When this feature is active, some operating systems may omit the hostname in DHCP requests, which can cause the router to list the client as “Unknown.”
You can also label devices by manually editing their names:
