Switch the option "Dial-up" To "Broadband"Try that
Why the forget, do you have dial-up? How old are you, >60? Go get some money fro a router, that would probably solve the problem.
How?If he actually has dial-up, then i'm willing to bet that it doesn't matter what he does in the setting for the router, the bandwidth probably won't allow the server to be online.
You said he should buy a better router to somehow replace his supposed dial-up service with broadband.
Anyway, have you tried switching routers?
