Hey @Doroszenko1980 I hope you're well and having a lovely day so far 😊 I'm sorry to hear that you're having issues with your broadband!
What exactly is going on? Is it completely down or are you experiencing drops in speed and/or connection throughout the day? Is the router completely dark or are any of the lights flashing?
Just to check, have you tried resetting the router by holding a pin in the reset hole for 45 seconds? 🙂
