This is a java programming language..
Help please?

try restarting the ps as a whole. i have one and i recently had the same issue, if that doesn't work it may be that your dad need to renew the contract.

explanation:

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.
