If the network is in ad-hoc mode, in addition to using the correct SSID and security settings, you
must use the channel indicated in the
Site Survey section and set the transmission rate to Auto or
the exact fixed speed used on the network.
Remember that high-speed ad-hoc mode and 256-bit WEP encryption can be used only on
connections to devices in the same product line as your adapter.
Select the connection profile for the network, choose
Details, edit the profile, choose OK, and
choose
Apply to put the new settings into effect.
Problem: An initially good wireless link fails, or the link alternates between good and bad
(the utility icon in the system tray goes from green to red, or constantly alternates between
green and red).
Solutions:
• On an ad-hoc network, the link may go up and down for a short while until the network
adjusts to the addition of a new member. A different BSSID may appear in the
Information panel each time the link comes back. The link should quickly stabilize; try
the solutions below only if the problem persists.
• The computer may be too far from the access point (or the nearest ad-hoc network
member). If possible, move closer. In some cases, changing the orientation of the antenna
(on one device or both) can help.
• There may be interference from a microwave oven, cordless phone, or remote control.
Shut down the interfering device, move it further away, or move away from it. If channel
selection is under your control, setting the access point (or all members of an ad-hoc
network) to use a different channel may solve the problem.
• Objects in the vicinity may be blocking or reflecting the signal. Metallic and other high-
density objects affect radio signals the most, but even a tinted or wet window can reduce
signal quality. Signal reflection, even from a remote object, can cause serious “multipath
distortion” (this also causes “ghosts” on television screens). Try a different location
(sometimes a small shift is all that is needed), or, if possible, move objects that may be
affecting reception.
• Make sure the access point (or ad-hoc network member) is working correctly. Check all
antennas, connectors, and cables.
Problem: A working, nearby access point does not appear in the Site Survey listing.
Solutions:
• Check the range, and check the environment for interference, signal absorption, and
signal reflection (see preceding).
• The access point may be set not to broadcast its SSID. If possible, change the setting;
otherwise, contact your dealer to see if an updated driver is available for the adapter.
