BT Broadband router keeps disconnecting (going yellow), anything I could do about this?

Had this fibre internet with BT for about 6 months now during this time nearly everyday the router randomly disconnects from the internet sometimes once or several times a dayRecently it's been happening much more so wanted to see what my options areIt's been really annoying when I'm on online meetings and get disconnected

I have my devices connected with Ethernet that's not the problem it seems it's just the router keeps going yellow

Thanks
