Noul chipset WiFi de la Marvell îşi umileşte adversarii

Cu ocazia târgului internaţional de electronice de larg consum, CES 2008, compania americană, Marvell, a anunţat lansarea unui nou chipset WiFi pe nume TopDog 11n-450. Acesta oferă o lăţime de bandă de 450 Mbps, cu aproximativ 50 de procente mai mult faţă de cât oferă chipset-urile actuale WiFi 802.11n (300 Mbps).

În plus, acest nou chipset oferă o rază de acces de cinci ori mai mare decât chipset-urile standardului 802.11g şi de 1.6 ori mai mare faţă de cele actuale (802.11n).

Totuşi, chiar dacă va fi prezentat la CES 2008, Marvell a anunţat că nu va distribui acest chipset mai devreme de al doilea sfert al acestui an. Aşa că mai aveţi de aşteptat cel puţin o jumătate de an până când vor apărea pe piaţă laptop-uri cu capabilităţi WiFi mai rapide şi mai performante.

Dar, pentru că performanţa vine cu un cost, ne întrebăm dacă durata de viaţă a bateriei nu va fi prea mult afectată de consumul indiscutabil mai mare al noului cip WiFi de la Marvell. În legătură cu asta, anunţul companiei nu spune nimic.

Totuşi, cipul TopDog 11 n-450 ar putea fi folosit la construcţia unor acces point-uri mult mai performante decât cele pe care le avem acum.

ALFA-­AWUS036H & ALFA-­AWUS050NH INSTALLING/UPDATING DRIVERS RTL8187, r8187, RT2800usb on UBUNTU

NOTE: For surfing Internet with ALFA-AWUS050NH on Ubuntu Jaunty with rt2870sta driver, you must use the Kernel "2.6.28-11-generic #42-Ubuntu", without change or updates the drivers modules. NOTE: The tutorial is not related to Ubuntu karmic. Driver RTL8187/Stacks-­mac80211 (ref. ALFA-­AWUS036h) ­- These drivers, for surfing Internet, are more stable than r8187, and fully compatible with Network-Manager 0.7 installed by default on Ubuntu 9.04. Network-Manager 0.7 installed by default on Ubuntu 9.04. ­- Supports all encryption without problems. (OPEN, WEP and WPA/WPA2) ­- With Compat-Wireless, the "injection" working, but for support “Fragmentation attack” (opt. -5) you need to install one patch. - The RX sensitivity and packets injection is less, related to drivers r8187. Driver r8187/Stacks-ieee80211 (ref. ALFA-AWUS036h) - This driver is recommended for use with the Suite of Aircrack-ng, but not particularly suitable for Internet connections, as less stable and disc...

Packetforge-ng

The purpose of packetforge-ng is to create encrypted packets that can subsequently be used for injection. You may create various types of packets such as arp requests, UDP, ICMP and custom packets. The most common use is to create ARP requests for subsequent injection. To create an encrypted packet, you must have a PRGA (pseudo random genration algorithm) file. This is used to encrypt the packet you create. This is typically obtained from aireplay-ng chopchop or fragmentation attacks.
