I set up my Linksys MX4300 Mesh with Firmware: DD-WRT v3.0-r60284 std (03/13/25). (EDIT: Screen shot shows the older firmware, but I've upgraded to the latest.)
Everything was working well, and I plan to share my settings soon. However, I’ve encountered a potential security issue.
To resolve connection issues with some of my Apple devices on 5GHz, I split the SSIDs—naming the 2.4GHz network “1WiFi” and the 5GHz network “2WiFi.”
Issue:
Despite enabling security settings on both bands (as shown in my screenshot), the 5GHz network appears as an open network. I can connect to it without a password and access both the router and the internet.
I've used different passwords for each SSID and "forgot" the old settings and rebooted the routers.
Additionally, the router interface reports the WAN as “Disabled,” yet it is clearly functional—I am posting this while connected via the supposedly disabled WAN. 😄
This issue occurs on all three of my MX4300 units, so it doesn’t seem to be a hardware problem.
Is anyone else experiencing this? Any insights would be appreciated.

looks like a apple bug. the network is secured. for your wan. "its disabled". that doesnt mean the port is disabled its part of the lan bridge then. but the wan port isnt acting as wan device. wan is disabled by default btw. watch the setup page (on the very left) you will clearly find out that its configured to be disabled.
about the so called security issue. maybe the user here did just press save but not apply. so he made a new configuration but forgot that the router will just reconfigure the interface after he pressed apply. save really just means save and apply really means "apply". apply does also save btw. but unlike save it really takes the setting _________________ "So you tried to use the computer and it started smoking?
