I can repeat the SSID using AR300M running the current 3.024 firmware, but when I try to configure B1300 it says that SSID is DFS and won’t let me select it.
It’s not DFS though, just a regular signal in the 2.4 band. I did disconnect AR300M from the signal before trying to repeat it using B1300. B1300 is using a fresh install of current 3.027 firmware with default settings.
I managed to repeat it after all using B1300. I had to scan about 20 times. 5 times I could select the SSID (it was not shown as DFS or it was shown twice, once as DFS and once as regular). Then of the 5 times, I was able to join the signal once. It seems to have saved correctly.
