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.
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.
