TurtlePink You said you live in an apartment, and people around you have Internet service, so my guess is that you already have an outlet in your apartment. If that's the case, they can activate it remotely, and instantly.
Figure out who your cable company is, and who your phone company is. Call both of them, and ask what they have to offer. If you live in the US, they will have a retail shop you can drive to, and pick up the equipment. Generally speaking, they will also have wireless routers available, that they rent as part of your monthly service fees.
Skip all the bullshit offers, and tell them that you only want Internet access, period. No TV, no phone, nothing else.
To request a service person, it may be a few days, depending on how busy they are in your area.
Just don't forget to set up a password for both the equipment they give you, as well as the network you set up. As in, read the instructions.
