This is a list of tools used for wireless network monitoring tools that can be used from your laptop or desktop system to find out network speed, bit rate, signal quality/strength, and much more. #1: Find out your wireless card chipset information Type the following command to list installed wireless card, enter: $ lspci $ lspci | grep -i wireless $ lspci | egrep -i --color 'wifi|wlan|wireless' Sample outputs:
What channel should I choose for my wireless network? Wireless Networking Forum FAQ A. For best performance, you should choose a channel at least 5 channels from y our neighbors' networks. Although 802.11b and 802.11g devices are designed to share the airwaves with neighboring networks, it is best to find a clear channel for several rea sons, chief among these: 1. Raspberry Pi Kernel Compile This tutorial will demonstrate how to cross compile the kernel for the Raspberry Pi on Ubuntu 12.04 LTS. The kernel is functional with both the Debian and Arch Linux Raspberry Pi images. First, install the package dependencies, git and the cross-compilation toolchain: sudo apt-get install git-core gcc-4.6-arm-linux-gnueabi Create a symlink for the cross compiler: sudo ln -s /usr/bin/arm-linux-gnueabi-gcc-4.6 /usr/bin/arm-linux-gnueabi-gcc
