Wireless Networking Forum FAQ. Follow these simple steps:•1. Get one wireless network card for each computer•2. Go into the network card properties and set the SSID to something unique. Make sure to set the SSID to the same value on each machine.
If you don't, the network will not work properly.•3. Go into the network card properties and set a channel for the wireless network to use. Make sure you set the channel to the same number on each machine. If you don't have the same value set, the network will not work.•4. If you don't want to share your internet connection, this should get you up-and-running. If you do want to share your internet connection, follow these steps: •1.
Also, keep in mind, when sharing your internet connection over an ad-hoc network, the host computer must be on, and connected to the internet, if you want the second machine to be able to access the internet. To test connectivity: •1. Regular filesharing setup and problems still apply to ad-hoc networking. You can also find an additional guide here. 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. When your neighbors' networks are busy, there is less a vailable bandwidth on those frequencies for your data, reducing your performance 2.
Your Access Point (AP) and wireless devices may not hear your neighbor's weaker wireless signals, causing degraded performance due to collisions 3. < p>In order to find a completely clear channel, you need to choose a channel that is 5 or m ore channel numbers away from your neighbors. You need to understand that the wireless channels tr anslate to a radio frequency. . -10 MHz 2437 MHz +10 MHz---------01---02---03---04---05---06---07---08---09---10---11--------- ~~~~~CHANNEL 06~~~~~ Notes: The channels available are governed by local regulations.

Linux operating systems comes with various set of tools allowing you to manipulate the Wireless Extensions and monitor wireless networks. 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: 0c:00.0 Network controller: Intel Corporation Ultimate N WiFi Link 5300 Please note down the 0c:00.0. #2: Find out wireless card driver information Type the following command to get information about wireless card driver, enter: $ lspci -vv -s 0c:00.0 Sample outputs: #3: Disabling wireless networking ( Wi-Fi ) You may want to disable Wi-Fi on all laptops as it poses a serious security risk to sensitive or classified systems and networks.

My current everyday machine is an old Macbook 2,1 that I’ve had for quite a long time, just over 4 years if memory serves me correctly. Now most of the time I really enjoy the Apple hardware in this machine, if not the software. There is, however, the more than occasional time that I need to make the hardware play nice with the software I choose to use. Most of the time it’s not a case of a piece of hardware not working at all but – because it is Apple after all – it working in a way I don’t want, or mostly working but not just not perfectly.
The Synaptics touchpad is one of these devices. Today, after finally getting the shits with accidentally getting somewhat near the touchpad with my palm and again finding myself editing the wrong damn sentence of my PhD thesis, I got my google fu out to find a solution. And what a solution I found. However! Like this: Like Loading... Tuning the Macbook touchpad in Linux | useless use of cat. The default synaptics driver settings in Linux are a little wonky, and are far from the feel of using the touchpad in OSX. I have spent some (read: too much) time tweaking these settings to a much more usable config. Getting under the hood Most distributions will automagically load the synaptics driver in X, so I’ll spare those details.
If your distro doesn’t do this, a quick google search should lead you to documentation on how to get the driver installed. The binary you will use to view and tune your touchpad settings is “synclient”. It can read and write touchpad settings real-time, without root privileges. To get a list of your touchpad settings, simply run “synclient -l”. Sensitivity The touchpad was far too sensitive by default. Synclient FingerHigh=50 Tap-to-click I deplore the click on Macbook touchpads, so tap-to-click is a must for me. I also enabled two-finger tap and three-finger tap to be my right and middle click, respectively. Corner buttons Palm detection synclient PalmDetect=1. Raspberry Pi | An ARM GNU/Linux box for $25. Take a byte! Mimo USB Monitor and Raspberry Pi - Anup Narkhede, Ruby on Rails developer, London. Since past few weeks, I’ve been trying to put my Mimo UM-740 touchscreen monitor to a good use. Sounds old school, but yeah we are talking about pre-ipad age when I used it as a touch screen skypephone device.
Follow this tutorial to configure the monitor as a primary display for raspberry-pi. Although I have explained the steps against Nanovision Mimo UM740, they should work with any displaylink USB monitor. My setup: 7 port powered USB hubRaspberryPi running raspbian wheezyMimo UM740 touchscreen monitorUbuntu 12.04 machine for kernel compilation Step 1: Prepare SD card Setup SD card with raspbian wheezyBoot using a standard hdml monitorUsing raspi-config, enable ssh server and disable the GUI mode on startup. Step 2: Compile Kernel with udlfb support First, we need to enable Displaylink framebuffer support in the kernel. 2.1: Install dependencies apt-get install git-core gcc-4.6-arm-linux-gnueabi 2.2: Symlink the cross compiler 2.3: Checkout source code 2.4: Configure 2.5: Compile References: 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 Make a directory for the sources and tools, then clone them with git: mkdir raspberrypi cd raspberrypi git clone git clone cd linux Generate the .config file from the pre-packaged raspberry pi one: make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- bcmrpi_cutdown_defconfig If you want to make changes to the configuration, run make menuconfig (optional): make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- menuconfig mkdir .. cd .. cd ../..
That’s it!
