Comment 9 for bug 1574196

I've an ASUS PCE-AC68 card and, years ago, I gave up configuring it with DFS channels. Apparently, it wasn't able to see them. I even thought that they were forbidden in my country...

Months ago, while I was doing some bandwidth tests, I decided to try again. I switched the channel to a DFS one in my router (an ASUS RT-AC68U) and, initially, the card couldn't see the new channel either. But I waited 5-6 minutes and, for my surprise, the card was able to detect it! I decided to wait so much time because I had read, somewhere, that DFS channels might take even minutes to be detected. And indeed, that was the case with this ASUS card. The Intel card of my laptop, though, detects it immediately.

My tests were made with Debian 9 and the driver "broadcom-sta-dkms" 6.30.223.271-5 .
