Recently, a few of my devices keep disconnecting from the router. For example, my PC disconnects daily, but my sky box and Alexa don't. My mobile does, and will show "Connected without internet". When looking at the router, all lights are lit, and showing no sign of lack of internet connection. This problem had happened before, but after a few weeks it disappeared. The only fix I have is having to turn the router off and on again, my devices reconnect fine usually for the rest of the time used. When i return to my device the next day, and sometimes even later the same day, I have the same problem again.
I have been with Plusnet for many years now, and I would hate to have to go to another provider, but I will if I cannot get a fix for the problem, because as you can imagine, it is getting really frustrating now.
