Home Internet and wifi extender

5GHZ is more than fast enough to play videos, online browsing, emails, etc.  At least with the Netgear device I listed above.  But, after doing further research, using the USB-C to access the Ethernet Port is like shoving a busy 4 lane highway into two lanes.  Bottom line, the Belkin adapter I listed above doesn't work.  Next, I'll try using the Extender switch rather than the access port and mount it in between the router and my shop,
