Earlier today I tried to load a Roku app on my device. However, it almost immediately told me I had no connection. So I went to the network settings page and found my home network had a strength of "Excellent" but when I tried to connect to it, it failed within a few seconds to connect to the wireless network. I then restarted the device several times to no avail. Every other device in the home is connected, however on some devices I have had repeated problems of Wi-Fi connection dropping recently, again even if the strength is excellent. None however have lasted as long as my Roku outage. I have also reset the modem and it still hasn't worked. This Roku is also the furthest away from the router, but only now is it having connection problems after over a year.
What makes my case different I think is that I have a Roku Express 3930X that's not connecting to the internet, but a Express 3700 RW that is. I have tried to get my 3930X to connect to a mobile hotspot, but it doesn't seem able to find one. My router is a Linksys EA3500.
Any help is greatly appreciated.
