Hi I have fibre pre COVID and all was working fine only recently has it become so unstable o can’t get a connect to my laptop and have to put hotspot on my phone on. We don’t zoom until 8 pm an obviously quiet time and my connection is unstable and audio horrendous that without hot spot I would be in real trouble. Help !!!! I have changed settings within the router and am set up next to the router but this is crazy what am I paying for ????
