Internet keeps dropping out

[Porter2]

Hi, our internet keeps dropping out intermittently. In the evening our the internet buffers whilst we watched Netflix's and during calls on Teams the internet cuts off. We have a smart thermostat which keeps disconnecting so we have no heating. Keeps saying our connection is fine, however this morning it's has shown a WiFi exclamation mark and an error. Help required please.
