Curing a in intermittent wireless connection!

Hopefully this will prove useful to someone and isn’t a repeat of previous posts. I recently spent 2 hours trying to work out why my wireless connection kept dropping out and requesting re-authentication. I finally realised that the keyboard/mouse wireless dongle and the Wi-Fi dongle were interfering (USB ports physically close on rear of computer case), the cure was a USB extender cable since when not a single drop out. I should have been quicker on the uptake but that’s life. Channel hoping wasn’t as effective as it should have been.
