Échange-bébé Nos petits amours grandissent tellement vite... Leurs besoins changent, aussi, j'ai pensé créer ce groupe afin de bâtir une base de personnes avec du matériel en trop, prêts à ÉCHANGER/DONNER/PRÊTER!

084f2db8c6 The most common variation of Ethernet found in home networks is the 100 Mbps 100BaseT variant, although many of other variations exist with speeds of 1,000 Mbps and beyond. The AP contains a radio transceiver (which transmits and receives radio signals), and most APs contain a router that directs your networked devices data to and from the Internet. Most computers today already have the wireless network adapter built in. This list provides an overview of all the bits and pieces you either will or might need in your network. Your access point (or separate router, if you have one) translates between your public and private IP addresses to send data to the right computer within your network. WPA is the minimum level of security you should choose, if at all possible. Hint: Dont forget the cables! (They dont always come in the box with your wireless gear, and theres nothing worse than having to run back to the store because you forgot a $3 cable!) Stuff You Need Quantity You Need Broadband DSL, fiber-optic, or cable modem connection One Wireless LAN access point (AP) One (or maybe more if you have a big house) CAT-5e/6 patch cable* Two: A short one, to connect AP to broadband modem; and a 100-foot one, for troubleshooting and emergencies Wireless LAN network adapters One per computer (usually preinstalled) Wireless Ethernet bridge One per other networked device with Ethernet port (for example, original Xbox) Home network router One (optional; usually included in access point) Wireless repeater One or more (optional) * Make sure that your broadband router, AP, and other gear comes with a CAT-5e/6 patch cable, or be sure to buy one separately in addition to the cable you need to connect the AP to the broadband router (if your AP doesnt come with a cable).
Network Address Translation (NAT): A process performed in your access point (or separate router, if you use one) to translate, or create a tie, between your internal networks private IP addresses and the public IP address assigned to your network by your Internet service provider (ISP). To reduce the stress of all this technobabble, heres a glossary thatll help you quickly get on your way: 802.11: The general standard, developed by the IEEE (the Institute of Electrical and Electronics Engineers the folks who create many of the standards for networking equipment), for wireless local area networks. Explore Wireless LAN (Wi-Fi) TechnologiesMost people just refer to their wireless LAN as Wi-Fi. network adapter (also network interface card, or NIC): A device that connects to an internal bus in a PC, which provides an interface between the computer or device and the LAN. A NAT router is a device that performs this translation and lets devices on your network using nonroutable private IP addresses communicate with devices on the Internet. To connect to a network, a device must know the SSID of the network. Wireless LAN Technology Frequency Maximum Speed Compatibility Availability 802.11b 2.4 GHz 11 Mbps 802.11g Obsolete, still supported in network adapters 802.11a 5 GHz 54 Mbps 802.11n (where 5 GHz is supported, at 54 Mbps) Obsolete, still supported in network adapters 802.11g 2.4GHz 54 Mbps 802.11b (at 11 Mbps) Now 802.11n 2.4 GHz or 5 GHz (not all support 5 GHz) 300 Mbps 802.11g (at 54 Mbps); 802.11b (at 11 Mbps); 802.11a (at 54 Mbps where 5 GHz is supported) Now How to Choose Wireless Home Networking EquipmentYou dont need all that much to put together a wireless home network. Wi-Fi Protected Access 2 (WPA2): WPA2 adds even further enhancements to WPA, including AES (Advanced Encryption Standard), which makes the encryption key almost impervious to current cracker attacks.
