Re: RPi 3B+ gigabit ethernet bad download speeds.

Maybe cachefly.net interprets 3 identical download requests in 11 seconds as a 'hostile' act and rate-limits or locks out your activity?

Unless I'm confused, isn't the SSID the access point name ? I created it and named it "RPI",

In case it affects the replies being given...

Can you say anything more about the access point you have created? What hardware is it based on?
