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.
