Help Prevent access to wireless networks from outside the building
Excess
transmit
range presents a special reverse problem. For example, putting an
access point adjacent to a second floor bay window invites anyone with the right software
on the street below to pick up and enjoy all network transmissions. We discuss some
possible solutions to this problem further on.
Problems with Network Connectivity
If you cannot connect to the wireless network, try the following:
Check Network Settings
1. From the
General
page, check that the Network Name (SSID) and operating mode
are correct. If the laptop is configured for ad hoc networking, make sure that the
channel is correct.
2. To correct these settings, click the
Networks
tab.
3. Select the profile being used.
4. Click the
Edit
button and make the changes.
Access Point Connection Problems
Check the preamble length setting in the Windows Device Manager “Advanced” tab.
If it is determined that a short preamble length is required to connect to an access point,
try changing the "Auto” (default) setting to "Long Only," this option always uses a long
preamble. Refer to "
Changing the Preamble Length Setting
" for details.
Check Security Settings
1. From the
General
page, check that the security settings are correct.
2. To correct the security settings, click the
Networks
tab.
3. Select the profile being used.
4. Click the
Edit
button.
5. Click the
Security
tab. Make sure that the settings for WEP encryption are correct.
