2. Move the access point (host/cradle) off the floor and away from walls and metal objects (such as metal file
cabinets). Metal objects, walls, and floors will interfere with your wireless signals. The closer your access
point is to these obstructions, the more severe the interference, and the weaker your connection will be.
3. Reduce wireless interference.
The most common wireless technology, 802.11g (wireless-G), operates at a frequency of 2.4 gigahertz (GHz).
Many cordless phones, microwave ovens, hospital equipments, refrigerator, LED, and other wireless
electronics also use this frequency. If you use these wireless devices in your office, your device might not be
able to "hear" the signals over the noise coming from them.
If your network uses wireless-G, you can quiet the noise by avoiding wireless electronics that use the 2.4
GHz frequency. Instead, look for cordless phones and other devices that use the 5.8 GHz or 900 megahertz
(MHz) frequencies. Because 802.11n (wireless-N) operates at both 2.4 GHz and the less frequently used 5.0
GHz frequency, you may experience less interference on your network if you use this technology.
Avoid possible wireless interference
4. Update the firmware or driver of your wireless dongle.
If you are using a wireless dongle or other similar devices to make the connection, getting the latest
firmware or driver updates may improve the performance. Visit your manufacturer’s website for the
updates.
