Thanks for posting back what worked for you. Always appreciated.
Network Connection Reset disassociates the AP (access point) and reboots the Roku, forcing a new network connection. You may find that rebooting your router may be necessary as well in some circumstances if you run into issue again.

Re: roku wifi says excellent wifi and has internet connection but apps wont work
I had same issue. Worked great then my apps wouldn't load. I finally replaced it with my older version of roku and it works just fine. I used the tip previously posted, went and reset my network connection, and it worked:) thank you to those who posted the solution
