Slow broadband speed

[DBuckle]

My broadband is slow. Less than 14MB.  I cannot download or stream. I keep running the tests that say the connection is good, which it is consistent, just very slow.  I was getting much better speed consistently with BT

I have the same issue. Our new BB is very slow - as evidenced by screengrabs from generic online wifi speed trackers. All weekend. Sunday night was a disaster - no one could watch anything on TV or their devices. Video calls glitch, even Whatsapp voice calls. Gaming experience is 'much worse' according to my son. 

The TV installer is coming soon, but can he fix the wifi? I got Q because we have the dish and I didn't want to burden the wifi, but apparently it needs wifi to work... 

I'd love to unravel the whole thing.
