Ultra fast 2, terrible download speed on wifi but amazing upload?

Is your download speed ok if you use an Ethernet cable direct to router?

Yea broadband is fine with ethernet into the router or any data socket.

Wifi used to be good until a week ago, 200mb+ via several devices, now I get buffering on videos.

Turned off 5ghz banding and changed channels on the router with no difference.

Have you tried a factory reset of hub but pressing recessed button on back and holding until lights flash about 20/30 secs

@imjolly Already tried this.
I've also unplugged all the cables and plugged them back in, I've tried testing the wifi speed with all Ethernet devices unplugged too, no change.
