As Wi-Fi hotspots are mushrooming all over the world, they let people have the chance to get rid of those inflexible network cables and surf on the net wirelessly in the WLAN. However, a high-performance wireless Internet access is not an easy thing for some users, because when contacting with your wireless network, your wireless network adapter may probably meet a lot of strange failures, which may seriously affect your networking experience if you don’t fix them in time, and the blue screen is one that among those common failures.
If blue screen shows on your computer immediately after you installed a wireless network card, above all, you need to check whether the net card driver you installed is compatible with your operating system, for example, if your driver is only available in Windows 2000, but you have installed it in Windows XP, well then your computer would be more likely to have a blue screen. Therefore, make sure you have installed the correct network card driver.
If your driver is compatible with your system and has been installed properly, you need to go through the installation of this network adapter, and check whether it has inserted to the right slot or port properly, for if you pull out the card from its PCMCIA port on the motherboard or its USB port just a few seconds after plugging it, blue screen would lightly happen, because frequent pullout and plug may make network adapter’s corresponding port confused and fail to identify this adapter. Additionally, if you pull out your net card suddenly when its LINK light is blinking, that would also leads to blue screen, or even worse, your computer or your network card’s port would be damaged.

What Are Network Patch Panels?
March 17th, 2010
Patch panels are used as the central point in a network where all the network cables terminate. It is the grand central station of the network. Networks that use these panels (and almost all modern networks use this technology) are consider “star-networks” or they use the term “star-topology.” This is because if you look at a drawing of your network, all the network nodes (nodes are end-points on the network and include things like computers and printer) all connect back to the central “hub” and it looks like a big starburst. Another term is “spoke-and-wheel” where the “wheel” is your hub and patch panel and the individual cables going out to your nodes (computers and printers) become the spokes.
They come in various types and configurations from the simple wall-mounted 12-port patch panel block, to elaborate 96-port (and more!) rack-mounted patch panel. As was mentioned above, patch panels are rated for speed. So if you are running Cat 6 cable, you will need a Cat 6 patch panel.
Network panels come in various designs and styles. There are patch where the cables plug-in straight (90°), or angled at a 45° angle downwards; there are panels with 110 style punch downs on the back and ones with tool-less punch downs; there are various number of ports on the panels. Check the internet for the vast array of styles available. There are also two different standards for network panels: T568A and T568B mentioned above. Be sure to buy the correct ones for the installation!
It is best to buy patch panels that are rated for both standards. Since the only difference between the two standards is the order of the colored pairs, most manufacturers rate their patch panels for both standards. They simply have both wiring diagrams affixed to their patch panels.
