Contact sensors, keypad etc. going offline frequently

Hello, I have been using Ring for a while now (a couple of years) and it has been working great. However, for the past couple of weeks - most of my sensors, range extender, keypad etc. have all been going offline very frequently. No changes to location of base station or location of other sensors etc. that should cause this. The only change is that my internet speed has increased to gigabit speeds. To ensure that it wasn't the faster Wifi causing this, I switched my base station to a hardwired ethernet connection but that didn't help either. I have reset the base station (including a hard reset using a pin) and nothing helped so far. Was there a recent firmware updated to the Ring base station that could be causing this? Thanks K
