Poor network connection

I love rain internet, but the signal is too low, as in you cant do anything with it, outside my area the network is perfect, but too poor in my area. I wanted to buy 5G but Im not sure if it's a good idea due to the connection. I live in Soshanguve block V V ext3 Kokolofute street 7364/19. It's a middle class area, most kids use Google classroom schooling and they are exposed to the internet. I think we are your target market but can you assist us with strengthening the network or advise us on what to do please...
