I see area SSID’s and I connect to my WiFi (see pics), Roku shows wifi signal strength is excellent, but doesn’t stream. Gives error 018 about insufficient download speed, but when I test download speed of router on my iPhone, it shows download speed of 400+ (see pic). I restarted router and restarted Roku, same thing. I tried connecting by Ethernet cable to the router and Roku works fine with streaming.
what do I need to do to get the wifi working with this Roku?
