@Fae Ok, thanks, but I think I'll follow this thread, I can't bear to spend time on the support. I have very bad experience with support and have wasted a lot of time trying to help them with bugs...

@Virgo What router do you have? this option is removed in site when router is adopted, I have all routers and this is the same on all of it. no direction option. @Fae Is this unsupported on routers...

@Fae yes it works now, but I think the EAP670 is too sensitive to radar. it seems that it detects radar of other access points nearby. I have also seen that on other access points from TP-Link

@Fae i did a test, the EAP670 does not work on any channels above 100, tested with 20, 40, 80 and 160 Mhz same test on EAP653 everything worked. The EAP670 reverts to non DFS channels immediately.

@127.0.0.2 wish I had a solution to the roaming problem, I have the same problem, I have mentioned this on the forum a few times before but I don't think tp-link can fix this or don't take it...

@127.0.0.2 it looks like roam event is disabled in 5.4.6 try and enable.
