5G Interference on higher channels

[TonyH]

Hi,
My take when I did some simple experiment is the antenna seems to be tuned towards upper channels so these channels give better
signal level. I am always setting the channel there.

The highest channels on 5Ghz don't have the same power restrictions in the US (or at least they didn't until a few days ago) so the upper-most channels in most SOHO routers have a higher output power than their lower counterparts.
