@jchaves2m As stated, use wpa 2 . My devices disconnect frequently when using wpa3. Channel change should not occur if manually set. i have learnt from my ownership of this router to reboot after...

@SamBurd 1.2.5 Build 20211208 rel.49262(4555) Is my firmware version in UK. Had to manually select the download from tp link site.

@Hobba ...Who's your ISP ?

@Manxx My log is empty all week. When it auto reboots on a Sunday morning, i get log entries then. No log entries is a good thing.

@Sbailey factory reset. Give it a go. After that when u change any settings...only one at a time then reboot.

@sirrah in modem mode apparently only 1 port of the hub 3 works.
