What Internet router do I need?

[Sean]

Hi I am looking for a new internet router, I am with Telstra and using cable internet.
In my house I have a lot of devices that use the wifi
I often have friends over and they bring their laptops and we play mine craft
There can be up too 20 people using internet at once and it drops out.
I need a router with fast speeds and that can handle slot of devices at once. I cannot spend a whole lot (max au$200) please do not send me links to places other than Australia. (eBay is fine).
Thankyou in advance
