HH6 5GHz very slow but 2GHz fine

I've recently noticed a problem with my 5GHz Wi-Fi connection so did a speed test to check.

Clearly something wrong using the 5GHz network. Can anyone help sort this as I've never had an issue before?

Can anyone help please?

Have you tried restarting hub to we if that helps? 

Have you tried changing the wireless channel  best using WiFi analyser to find best available channel 

Remember that the 5ghz network is faster but does not cover same distance from hub as the 2.4ghz

I haven't restarted the router as yet. In fact having looked at the last reboot of just over a day I'm wondering if that's where the issue started. The 5GHz network has been fine for years.

Haven't tried WiFi Analyser but will do so.
