Wifi hotspot problems

[Jadzki96]

Hi. Am new here.

And well I wanted help.
You see we 3 friends hang around a lot.
And one of my friend has wife hotspot.

We all have Galaxy's. My S5 can connect to his S3 wifi hotspot. But for some reason my friend with his S4 he can not, I was wondering can anyone help?

Thank you.

Not enough information. Can the S4 connect to other wifi routers (a hotspot is a router) set up the way that hotspot is set up (password or no password, type of encryption if a password is used, etc.)? Can other S4s connect to that hotspot? That's how you narrow down the source of the problem. "It doesn't work" doesn't work in fixing things.
