I have a new laptop and i want to access internet ...

Let me get this right-

A. You don't want a wired connection "to the wall"

B. You don't want that "part" that looks for nearby networks, which is, IMHO , Wifi (Wireless connection).

Any more demands? 

It's a bit complicated to understand what you want.

anyway, you mentioned the two choices you have: 1. use a direct modem with wires connection. 2. use a wifi (wireless) connection, that you need atlist once to look for you network and set it (afterwards it will be automaticaly recognised by your laptop).

Those are the two realistic options you have.

I noticed you don't have much expirience, so you should ask someone who knows about this subject, like a computer store or a technician.

I-net access via modem has been pretty much superseded at this point by broadband technology offerings -- i.e. xDSL or Cable. Check for ISPs "Internet service providers" in your area that offer broadband plans, with price/performance/reliability characteristics that will meet your needs, or at least, be acceptable to you. [When] you finally sign up for a broadband account, you most likely will receive a CPE "customer premises equipment" device, more commonly referred to as a "broadband modem". At this point, you can pick up a residential router (very inexpensive) that will connect to your "broadband modem", and in turn, you will be able to connect your laptop to the router via a standard Ethernet cable. You may also purchase such a router with WiFi capability, allowing you to either plug in via cable, or connect wirelessly to the Internet. You may disable SSID broadcasting on the WAP/router combo, and configure your notebook so as to avoid the "looking around for networks" you wish to avoid. Should you require clarification or expansion on any of these points, simply post your question here on Yedda, or feel free to e-mail me direct....
