I was listening to a show on Prime when the internet connection failed on the stick in my TV in the living room. I am working from home so internet is definitely needed. I had no failure to my work connection and my phone still showed a connection as well. I tried resetting the network and it gave the 014.30 Error Code saying it couldn't even connect to wireless even though it obviously sees it is there signal strength "Excellent." Then found out the same thing happened for the the Onn.Roku TV in the bedroom. Reset the router just to see if that would help. Did not. Did a network reset and factory reset. No change. Double and triple checked everything including passwords. Nothing. I even disabled the ping setting as some says this helps with wireless connectivity issues. Nothing. Oh and I tried a USB system update on the TV this morning to see if it would correct the issue. I don't know what else to do. Any other ideas?
I don't know if your models are ones that would be affected by this, but ...
Your problem may have been caused by a recent update to your router that affects some Roku models. This has been reported lately with equipment from Comcast/Xfinity and Cox, but there may be others.
Affected users report their Roku locates the network and reports the connection strength but then fails to connect. The solution is to reconfigure the router to switch it from g/n wifi protocols back to b/g/n. If you don't have access to your router's control panel you may have to have your internet provider do it for you.
