Hello
I stay in a 4floor building.
We are 4brothers who stay on one floor each.
I have a router placed on the 1st floor which covers only one floor and partial ground and the floor above.

Which router and extenders should I buy so that my internet is shared with all my brothers.

I saw these type of networks in hotels and schools. I have. 20mbps connection which is enough for our use.
I am ready to spend some good money as it's a one time investment and shouldn't be a headache frequently.

Please help

Thanks
