I have four iPads, one iPhone and two Wi-Fi printers, how much will they affect the speedtest
If you're running a speedtest and all of your wifi devices are accessing the internet, it could have a big effect.
For example, if the phone is downloading a file while a tablet is syncing files to an online site, expect them to hog some of your available bandwidth and for your speedtest to show lower results.
But if they're on but not in use, they shouldn't have an effect.
