Nah the laptop is new, and im told for my uncles laptop whereever he went, be it my cousins houses, they connected him no problem. With no cables required.
But how? Like one day my friend brought his laptop over and said he wanted to connect. He asked me what was my connection name. Right there I wasn't really sure. In my network connections it just says currently connected to "Network".
Is that it? That sounds too simple.
Okay...then it's wireless networking 101.
When you have a wireless network, the network has a name (so the wireless device can find it). The network name can be anything you want, however when setting up the network, if it wasn't changed, it will usually be the name of the wireless router (D-Link, Netgear, Linksys, ect).
If there is wireless security on the router (WEP or WPA) that will also be needed for the wireless device to connect (think of it like the deadbolt on your front door. Each family member needs the key to get into the house. Same thing with a wireless network. Each wireless device would need the key to gain access to the network).
If you have both pieces of information you should be fine having other people connect to your network.
All this is assuming you have a wireless router connected to your modem (or was provided a wireless gateway [modem/router combo] by your ISP) to provide a wireless network in your residence.
