As the technology advances, now many devices can support hot plug, such as USB devices and 1394 devices. However, essentially, most hardware operations should be completed after the power supply is cut off, otherwise it may cause computer crashes or even the permanent damage to the hardware.
Sometimes computer may go dead if the wireless network card is pulled out suddenly from its related port. This failure occurs in a relatively high frequency. The reason why this failure happens is that many PC users think this wireless network card’s USB port or PCMCIA port supports hot plug, and it can plug and play. Actually, they take this plug-and-play function as random plug and few of them know that this wireless NIC card should not be plugged when working, for it is not only easy to hurt the card and its corresponding computer interface, but also likely to cause system crashes.
If your computer freezes up because of wireless network adapter plug, firstly, you need to confirm whether you have performed this action when the card is working, if so, you have to restart your computer.
In addition, in order to avoid this error, you’d better stop processes like information transmission and it’s best to disable your wireless network adapter in Device Manager before pulling out it.
Step 1 Click Start and select Control Panel.
Step 2 Double-click System to open the System Properties sheet.
Step 3 Click Hardware and choose Device Manager.
Step 4 Right-click the Network adapters and look at its properties.
Step 5 Disable and plug this card.

Wireless Network Card Troubleshooting – Computer Crashes
December 5th, 2009Troubleshooting Two Common Network Card Driver Problems
November 29th, 2009
One, your PC is slowing down after installing network adapter drivers. When you finish the installation of your net card driver and restart the PC, you find the boot up is markedly slower than before. Firstly, ensure that you have set up your compatible driver properly.
Commonly, it is in gear that the startup becomes much slower than before after a single computer experiences a network configuration, for the system will detect the adapter one more time. Surely, if the system freezes up for a long time on start, you should scrutinize the machine for other failures.
Besides, if you haven’t specified an IP address for your net card, your system will search one for it automatically on startup, which will take about 10 seconds. Even though your NIC is not in use at present, you’d better assign an IP address to it, and simply disable this card in the BIOS so as to boost the computer’s boot up.
Network card itself is less likely to have problems. The failures usually come from its drivers or the mismatch of transmission rate between the computer and the adapter, for these you can unload the driver and then readjust the correct network adapter parameter.
Two, your net card driver is broken while cleaning virus or because of shutting down the computer improperly.
If your network adapter programs are damaged and the adapter can not work, the network is unreachable and the net card light is on, go to the Device Manager (Start / Control Panel / System / Hardware / Device Manager) you will find a yellow exclamatory mark beside the Network adapters, which indicates that your net card driver is working irregularly, you need to unload and reinstall it.

Broadcom WLAN Network Adapters For Home and Enterprise
November 7th, 2009
Are you looking to make the entire connectivity infrastructure of your organization wireless? Among the best products you can consider are Broadcom WLAN network adapters. These products can work with any standards compliant product to deliver an end to end connectivity infrastructure where the only case of wires being used would be power cables and in certain cases, primary connectivity of extremely high speed. Broadcom products are reliable and affordable.
One of the key product lines from the company is Broadcom AirForce. This is a family of products which includes really advanced and sophisticated WiFi circuitry. The devices are usable in end user devices like mobile phones and laptop computers to enterprise grade networking solutions like gateways and access points. Blade servers from various companies are also known to integrate these solutions. The company has been true to IEEE 802.11 class standards.
You can find Broadcom solutions in the AirForce family include 802.11 a, 802.11 b, 54g and the Intensi-fi class products. These products are specially designed to act as a component on the devices which are interoperable, provide the best possible security and still are really easy to use. These products are able to satify all the consumer demands. You can find Broadcom solutions in products from Linksys/Cisco, Dell, Motorola, Hewlett Packard, Belkin, Lenovo, Apple, eMachines etc.
The main features of Broadcom solutions are their all-CMOS design and SmartRadio performance. These are specially enhanced technologies which make it possible for the device to deliver the best performance even while consuming the least amount energy. The company has also made great efforts to ensure that the products from the company have a common architecture. This means that design and deployment of a complete WiFi solution is a very easy task.
Another really important innovation made in the WLAN sector by Broadcom is the OneDriver software. You do not have to fiddle around with a number of different driver software packages. The company solutions. Not only does it make deployment of the WiFi infrastructure easier but far more simple and easy to administer and upgrade. Driver upgrades would never be a headache again.
The company has also delivered a number of standards based enhancements. Consider for example XPress Technology and 125 High Speed mode. These technologies can substantially enhance the overall throughput of the network. Then there is BroadRange. This technology makes it possible to get the best performance even at the edges of network range. Imagine having a directional antenna range in all directions. SecureEasySetup makes security settings a push button solution.
Other main features of these products are support for WPA and WPA2 as well as AES encryption. The devices also support CCX4 Cisco Compatible Extensions. You can deploy routers and use scanner and detector software solutions to do network security testing. Wireless communication in PC and printing devices has never been easier. Broadcom WLAN network adapters make getting rid of wires a really easy and affordable task.
