Q: Which factors affect the wireless signals?
A: 1) The walls in the house are main obstacles. Because wireless LAN adopts wireless microwave
frequency range, the signals received by wireless receiving devices behind the obstacles will be
rather weak.
2) Physical obstacles not only hold up the wireless signals but also absorb the electromagnetic
power.
3) The working frequency range of IEEE802.11b/g standard is 2.4GHz, but other electrical devices
are also working in this frequency such as microwave oven, Bluetooth device, wireless telephone
and refrigerator, etc. If there are strong magnetic fields beside, wireless network will be affected.
4) If there are multiple wireless devices in wireless environment, channel conflict and wireless signal
interference may occur.
5) The strong signal interference resources such as wireless transmission tower, electric welding
machine, electric car or electric transformer may disturb the wireless signals or devices.
6) The weather may affect the outdoor wireless signals greatly. The signals attenuate sharply in
lightning storm or gloomy weather. However, the signals in sunny weather can transmit farther.
Q: How can I improve signal-transmitting quality?
A: 1) Choose a proper place for wireless Router. The requirements are as follows:
1. The place should be high enough for the Router to transmit the signals widely, thus the obstacles
and dead spots will be greatly reduced.
2. When you choose the place to set the Router, make sure that the signals pass through fewer
walls.
2) Modify channels to reduce wireless disturbance.
Note: When you set your wireless transmitting channel, keep above 5 channels far away from other
wireless signal channels.
3) Keep the wireless Router far away from household appliances to reduce the disturbance of the
signals.
4) If the antenna of wireless Router is detachable, you can change it for a higher gain one to
enhance wireless signals.
