SYMPTOMS
When you try to connect your Microsoft wireless adapter to a wireless network, the signal strength that is displayed in the Broadband Network Utility may be lower than you expect, and may fluctuate.



CAUSE
This issue may occur for several reasons, including the following:
 * The computer that you are trying to connect to the wireless network may be too far away from the wireless hardware, base station, other wireless adapters, or third-party wireless hardware that you are trying to connect to.
 * The use of 2.4Ghz cordless phones may interfere with the wireless network signal.
 * Radio waves and microwaves outside the home can create interference if your network spans from building to building.



RESOLUTION
To resolve this issue, use the following methods until the issue is resolved.

Method 1: Relocate Wireless Networking Equipment
If your wireless adapter is out of range, relocate your wireless network equipment so that there is the least possible distance between them. If your wireless base station is at one end of your location, with other network equipment between the base station and the adapter that is the longest distance away, try to put the base station as close to the center of your location as possible.

Method 2: Locate and Remove Sources of Signal Interference
To locate and remove sources of signal interference, follow these steps:
 * 1) Unplug any cordless telephone equipment that is in the vicinity of your wireless network. If your network spans between two or more buildings, unplug cordless telephone equipment in all locations. If this resolves the issue, replace your wireless telephone equipment with wired equipment.
 * 2) If your network spans between buildings, and you believe that there is a source of external interference, try to locate the source of the interference. If the source of the interference cannot be removed, you may be able to work around it by relocating your wireless equipment. Experiment with different positioning until your wireless signal strength improves.

Method 3: Reinstall the Wireless Adapter that Is Experiencing the Issue
To do so, follow these steps:  Remove the adapter in Device Manager.  Make sure that the adapter is plugged in if it is a USB adapter, or that the adapter is physically present in your computer if it is a PCI card or PC card adapter. Click Start, right-click My Computer, and then click Manage. In the left pane of the window, click Device Manager. In the right pane of the window, double-click Network Adapters, right-click your wireless network adapter, and then click Uninstall.
