Internet Router for AUS?

[john]

Hi im living in an Australian boarding house and long story short the internet is really bad and i need a router but i dont know anything about them. E.g. pricing, speed and quantity. Wondering if someone could shed some light on my issue and help me decide
Im just going to get like a usb router with some plan
my phone teathering is bad
every internet source i have is bad + i live in the city so a router would be fast
