This has driven me absolutely nuts over the past few days as my Steam Link has been absolutely useless on 5GHz WiFi.
Hope this helps someone else:
I was getting intermittent latency spikes that made my Steam Link unusable and after a lot of pain and exhaustive testing, I found that the issue was one of my Canon printer utilities.
Uninstalled:
C:\Program Files (x86)\Canon\IJ Network Scanner Selector EX (this is for my wireless Canon printer)
And now I don't get a single ping to the DGW >1ms in an hour whereas before there were spates of >100ms for 4-5 seconds every 30s or so.
I uninstalled the utility and peace is restored on Earth in time for Christmas
What makes this even more weird is that it's only just started happening. (Windows 10).
