@art3mk I would use /32 instead of /24 for allowed address. you only need to allow your own ip. also change Address = in the client file, I myself have an ER605 and do not experience the same...

@Cotchet Try uncheck 6 Ghz

@Phreaknes then you have to check the switch ports that go to the access point and router. there you must use switch port profile all If that doesn't work then I have no more suggestions.

@Phreaknes double check that the switch is connected to port 11 or 8

@Phreaknes it is not a wireless network, you configure vlan here.

@Phreaknes it is in the same place where you configured vlan, wired networks and lan
