Before these changes, my WiFi worked only 99% of the time
But, I had to constantly cycle WiFi on my iPhone / iPads to reliably connect to new links (Tweets from notifications would take long to load, images in FB Messenger wouldn't load, going to new web pages were slow, etc)
I used to always reboot my cable modem and wifi network hoping it would fix speed issues (it sometimes did)
Now all links load instantly 🚀 and internet feels 10x faster
No rocket science below, but it made a huge difference. Also, I'm not sure if all of the below is required
YMMV

Principles

Speed tests are NOT a good indicator of working WiFi

Speed tests routinely tell me I have high download / upload speed & low latency but my experience was poor
Make sure you pause high bandwidth hogs while running the tests (for me these are Nest cameras and Google Backup and Sync) — Bell actually has a speedtest on the modem (you go to it via your modem admin panel) that blocks all local internet traffic to do an accurate speedtest
After all the changes these benchmarks didn’t change much 😌 (and some went lower!), but my experience is clearly better
