I have a 7530-AX and on the whole it's been good - but for some reason the 5GHz service keeps switching off; wondered if you'd had any similar experience?

No, can't say I have. Does your SSID disappear for some time, or is the 5GHz setting turning off permanently?

I've read about routers disabling 5GHz when they detect RADAR, because 5GHz can interfere with that use, and RADAR has higher priority. Here's an article on this, official from the manufacturer and for your specific model (another point for them in my book):

Thanks! This might be the clue I need - looks like the channel I’m using might be more prone to RADAR interference. Trying out a few changes now to see what effect it has.

It could also be a client issue; I configured my access point to choose the best channel for 5GHz and sometimes when it picks a DFS channel, some devices just can't connect.
