----------
If I understand the submitter correctly, we are discussing different issues here.
I would like to clarify this, since an (in my opinion) unrelated issue ([[https://bugs.lede-project.org/index.php?do=details&task_id=558|#558]]) was just marked as a duplicate of this one.

The submitter described:
  * there was an automatic switch of channel
  * when trying to toggle the state of the wifi interface (via luci), it stopped operating at all

I do not think, that the channel switch (due to DFS) is the problem of the submitter. The real problem seems to be that he needs to reboot his router in order to get the wifi working again.

As a sidenote:
Here in our freifunk community we are working on improving DFS handling. We have to deal with a lot of channel switching and toggling of the wifi state, but we did not encounter a wifi device getting stuck. Thus it sounds like the above issue is not related to DFS, but to the BT Home Hub 5 (we are using mainly Ubiquiti Nanostations and TP-Link CPE).

Or do I misunderstand something?
