Chapter 6 Troubleshooting

My PC Card seems to be installed correctly and it says that it is getting a

link, but I can’t access the internet. What should I do?

First, disable any network adapters installed on your computer. If these adapters

were installed prior to the PC Card, they may be preventing an Internet con-

nection. If using Windows XP, right-click on My Network Places, then click

Properties in the next window to ensure no network bridges are installed on the

computer. These can also prevent Internet connections.

When I plug the PC Card into my PCMCIA slot, nothing happens or it detects

and goes away. What should I do?

The PC Card slot must support 32-bit Type II PC CardBus (check with the com-

puter manufacturer to confirm). If so, try shutting off the computer and restart-

ing with the PC Card already plugged into the PC Card slot.

Can I use an 802.11g PC Card to connect to an 802.11b access point?

Yes, an 802.11g PC Card can connect to an 802.11b access point.

Will cordless phones interfere with the PC Card?

The 802.11g PC Cards use 2.4 GHz frequency. If your cordless phone uses this

frequency, problems may occur. Different cordless phones use different frequen-

cies, and generally include a label stating which frequency they use. If problems

with interference caused by your cordless phone occur, try changing the channel

of your wireless network. This can sometimes clear up interference issues. Any

wireless device using the 2.4 GHz frequency can cause wireless interference.

Can a wireless signal pass through floors, walls, and glass?

The effect of the physical environment can have varying effects on signal

strength and quality. The denser an object (a concrete wall compared to a plaster

wall, for example), the greater the interference will be. Concrete or metal-rein-

forced structures cause a higher degree of wireless signal loss than those made of

wood, plaster, or glass.

What is WEP?

Wireless Encryption Protocol (WEP) is the standard encryption mode for

802.11g communications.
