On my RV340 router, I've noticed that I can't uncheck the option Device Management (under VLAN Settings) for VLAN1 even after having checked this for one or more other VLANs. I tried a complete reset of the router but I still not could not uncheck device management from VLAN1 and ensured I was on the latest firmware revision 1.0.03.24.
Any pointers on whether this is by design or can be rectified would be greatly appreciated. Thanks for your time.
