same problem on ubuntu and windows controller, suspect it has something to do with daylight saving time, I have adjusted the clock at the os level but it seems to make no difference

@Krade yes I see now that you have the latest official version, I don't quite understand why you have a problem with the default vlan, what ip do you have on the wan interface on the router?...

@Krade you have a fairly old router firmware, try upgrading to the latest one. you can find it here. https://community.tp-link.com/en/business/forum/topic/857570?moduleId=794 What controller version...

@Vishlamba No, there hasn't been any firmware for the ER605 yet.

@Vishlamba You need Omada version 6.2 compatible router firmware to use that feature.

@lcreasy so good
