Slow & laggy wireless performance, previously solid

[#1]

Hello, our wireles performance has dropped recently, maybe over the past week or so, several devices which worked well recently are now lagging/stuttering.

All devices have been restarted, Plusnet Hub has been switched off at the mains this morning and left for 5 minutes or so then restarted.

Grateful for any help!

Also experiencing this over the last week. Dropping out every day and yesterday my wireless speed on my PC was 0.7MB where I usually get 9-13MB. All our devices (tablet, phone, consoles) suddenly have a very poor wireless connection. 

I cannot use the wirelessly without an ethernet cable.
