I have a Roku Premier. Eversince the new software update my roku keeps diconnecting and reconnection to and from my wifi. Non of my apps work and most of the time my remote lags or does not function. I CAN NOT WATCH ANYTHING. THE ROKUS WE HAVE ARE BASICALLY USELESS. My daughter has a newer one but once she opens an app. It doesnt work and says check internet connection. Our internet connection is excelent so make it make since. Never had a problem.until the update. We need a softeware patch or rollback for the premier rokus. Andvyes we have already manually checked for updates. NOTHING
There are a couple of network connection problems recently being reported that have been caused by updates to routers. These have primarily been reported with routers supplied by internet providers, but it's possible they could also occur with user-owned routers that have received updates.
ROKU LOCATES NETWORK BUT CANNOT CONNECT Some router updates have changed the router's connection settings from b/g/n to just g/n, causing some Roku models to lose their ability to connect to the network. The solution is to set the router's configuration back to using b/g/n.
ROKU CANNOT FIND LOCAL WIFI NETWORK Some routers (reported from Xfinity and Cox, but there may be others) have had their 2.4 GHz wifi band turned off, leaving only the 5 GHz band operational. Devices with single band wifi radios, notably Roku Express and Premiere models (but not Express 4K models) as well as many other single band devices can not even see the 5 GHz band. The solution is to reconfigure the router and turn the 2.4 GHz band back on.
If this problem was not caused by a router update deactivating the 2.4 GHz band, often a restart of the router (even if other devices are still connecting) followed by a restart of the Roku will allow the connection to be reestablished. Depending on your Roku model and Roku version number you'll find the System restart option under either Settings > System or Settings > System > Power.
If you need to make configuration changes on equipment supplied by your internet provider but you have no access to its settings, you may need to request your internet provider to make the changes for you.
