The WiFi signal to my mobile is very low (only one or two bars) or sometimes there is no connection

I can't say anymore than other than I have a very low signal. When I'm not at home and use mobile data I get a full signal. What could that be?

My mobile has a very low signal or sometimes no connection when at home. I get full connection when away from home on mobile data
