Roku mobile app

[emers102]

I have an iPhone 13 on iOS 17.7 and a Roku Express 4K+ connected to my Samsung TV. My Roku app somehow disconnected from the device and simply refuses to reconnect over WiFi or via IP address. It tells me when I try that method that “A Roku device was not found at this IP address.”

This issue happened suddenly for me a few months ago, for the first time in over 2 years of owning the Roku device, but I since lost the solution I had found for it at the time (I recall it being in my phone settings, where I turned a setting I had never heard of off and on again). Nothing regarding my internet service has changed since then.

I can confirm that the Roku device and my iPhone are on the same network; I have the Local Network setting enabled in my iPhone settings and the Control by mobile apps setting in the Roku set to Default; I have restarted both the Roku device (also unplugged it and plugged back in) and my phone; I have reinstalled the app on my phone; and all my software is up to date. NOTHING is working to fix this. It is most certainly not an issue with my router. I am at a loss for why this is happening and need creative solutions, as none of the responses to similar posts in this forum have been helpful. I can provide serial numbers etc. if necessary.

It is upsetting how common a problem this seems to be for Roku users, and I hope it gets resolved if its cause is internal.

@emers102  The majority of connectivity issues tend to be related to channel congestion. I'd recommend you find a iPhone app similar to WiFi Analyzer for Android. Once installed, you'll be able to view how many others in the area are using the same channel/band as you are then log into the router and switch to one that's less congested. Depending upon the type of home you live, using the 2.4 gHz band rather than 5 gHz might also be of help since it has stronger throughput where walls and obstructions are concerned. Hope that helps.
