How to use an alternative Wifi connection manager in Ubuntu

Wicd is an excellent swap-in replacement for NetworkManager. NetworkManager is the system software that sits in the notification area and handles network connections.

Configure Ubuntu firewall using Firestarter

You might not realize it but Ubuntu has a very powerful firewall built in. However it isn't activated out of the box. Some firewall configuration tools are provided but aren’t easy to use and definitely aren't recommended for those less-versed in networking fundamentals.

Manual Wireless Configuration with iwconfig in Ubuntu

NetworkManager will automatically detect and configure your wireless connections, as will KNetworkManager. However, you can manually configure your connections with wireless tools such as Network Manager Editor and iwconfig. Wireless configuration makes use of the same set of wireless extensions in the Ubuntu main repository, wireless-tools package.

Understanding Security for Wireless Networks

On a conventional wired network, physical security is a given: If someone plugs a computer into your hub, you'll know about it immediately, and you can trace the physical wire back to the intruders computer. On wireless networks, however, anyone who comes into range of your wireless access point can tap into your network and intercept signals from it.

How Remote Assistance Works

The two parties in a Remote Assistance session are called the novice and the expert. (On some screens and in some documentation, the expert is referred to as the helper.)

How to make Windows Vista Start Faster (Almost Instantly)

You can optimize Vista all you want, possibly shaving 15 or 20 seconds off your boot time, or you can approach the problem from a different angle.

Ubuntu: Connecting to a Wireless Network

A wireless (Wi-Fi) network is, as its name suggests, a network that does away with cabling and uses radio frequencies to communicate. It's more common for notebooks and handheld computers to use wireless connections, but some desktop computers also do. Indeed, it's increasingly the case that many workplaces are switching to wireless networking, eschewing old-fashioned, cable-based networking.

Stop waiting for an IP address and make Ubuntu boot up faster

If you use an Ethernet or Wi-Fi connection to access your network, you might find that Ubuntu spends a few seconds during each boot acquiring an Internet address. This will be characterized by a long pause while nothing seems to be happening. Therefore, one way to provide an instant speed boost is to give your computer a static IP address.

How to Install Windows Wireless Network Device Drivers in Ubuntu

NdisWrapper is effectively an open-source driver (technically described as a kernel module) that allows Linux to use standard Windows XP drivers for wireless network devices. You might describe NdisWrapper as being a translation layer between the Linux kernel andthe Windows drivers, which can be installed using NdisWrapper's configuration tools.

WEP VS. WPA in Ubuntu

Some wireless networks are protected using either the Wired Equivalency Privacy (WEP) or Wi-Fi
Protected Access (WPA) systems. WPA is effectively an updated version of WEP and offers stronger protection. There are actually two versions of WPA: WPA and WPA2. WPA2 is newer and corrected several security flaws in WPA. Both work in roughly the same way.
