Wireless Troubleshooting

What i need for home wireless network between desktop and notebook?

I have wireless card on my laptop, but my desktop pc doesn't have one. The thing i want is to share adsl internet from desktop (usb) so i can have it on my laptop everywhere in my flat (60 square meters, two walls) and to have a standard file sharing network between them. So can i do this by adding wifi usb stick into desktop? Or i need a router?

1. you need wifi usb stick and a wireless router.
2. You need a wireless router. It is possible to plug the router into your PC and share the internet but needs careful setup. It is probably better to talk to your ISP about a wireless router that will replace the USB modem.
3. what you need is only a wireless router which can separate the internet to differenent computers!
4. There are three key parts to a wireless internet connection: 1. A modem. This is the device that will connect to your ISP (or Internet Service Provider -- the people who you are paying to serve you with internet connectivity). High speed internet modems can be DSL (using a phone line), Cable (using a coaxial connection to your television provider), Satellite (using a coaxial connection to your Satellite Internet dish), or Wireless (connecting over-air to a provider such as Clearwire). 2. A router. This is the device that your computers will use to connect, wirelessly, with each other and with the modem. You will want to set this up with some sort of security; the most commonly used is a WEP key, which is just a 32 (or more) character code that your router knows, and you tell your computers to use, to connect -- so that unauthorized users can't connect to your network. 3. A wireless network card or device. This is either a USB, external device, or a card (PCI or PCMCIA, for laptops) that is installed on each of your computers, that allows your computer to communicate through the air, and connect to your router. The modem needs to be connected to the router (by a CAT5 or CAT6 network cable), and also to your ISP's method of internet transport. Alternately, some modems have a built-in wireless router/access point, but I generally prefer to use a router and turn off the modem's wireless capability, for the improved firewall most routers have. You may also have to connect your PC to the modem directly (through a cable) to configure it, and the router may need to be connected similarly to set it up as well, but can be disconnected and used wirelessly once this is done.
