The solution to the problem of slow speed of wireless internet

These days a friend of the computer internet speed is very slow, look at the connection properties of the wireless network, found that the connection rate incredibly only 2Mbps, and sometimes only 1Mbps. The computers in the wireless LAN are in the same room, the previous connection rate is normal 11Mbps. This is a puzzle to my friend.

The specific solution is as follows:

Wireless network equipment can adjust the transmission rate intelligently to adapt to the change of wireless signal intensity and ensure the smooth of wireless network. It is recommended that you do the following to restore the original transfer rate.

First, check to see if the wireless card energy-saving mode is turned on. In the use of energy-saving mode, the transmission power of wireless network card will be greatly reduced, will cause wireless signal weakened, thus affecting the wireless network transfer rate.


Second, see if there are any shielding between the wireless devices. If the wireless network card, or between the wireless network card and the wireless AP has a shelter (especially metal shielding), will seriously affect the transmission of wireless signals. It is recommended that the wireless AP be placed in a higher position in the room.

Third, see if there are any other jamming devices. Microwave ovens, cordless phones and other devices will have a greater interference in wireless transmission, resulting in a decline in communication rate. Most microwaves use the 7th to 11th channel of 14 channel in the 2.4GHz band, so for wireless devices that use IEEE 802.11B protocols, the communication channel is fixed to 14 (last channel).
