It is better to choose WiFi wireless channel 1 or 11.
Normally, the default channel is 6, which can be used normally in a single wireless network environment, but if it is within the coverage of multiple wireless networks, the wireless router uses the default channel 6. There will inevitably be conflicts and interference between them, which will affect the connection quality of the wireless network.
Although the wireless network can have 13 channels, there are only three non-overlapping channels, that is, channels that do not interfere with each other: 1, 6, and 11 (or 13). If you want to reduce interference from other WiFi networks and ensure stable operation, it is recommended to use the three channels 1, 6, and 11 (or 13).
Disadvantages of wireless channels
The commonly used IEEE802.11b/g works in the 2.4-2.4835GHz frequency band, and these frequency bands are divided into 11 or 13 channels. When there are more than two APs within the wireless AP wireless signal coverage, different frequency bands need to be set for each AP to avoid conflicts among the available channels. The default setting of the wireless devices used by many users is Channel 1. When two or more such wireless AP devices "encounter", conflicts are inevitable.
The conflict of wireless channels is so concerning. In addition to the exponential growth of home or office wireless equipment due to the continuous decline in prices, the inherent lack of wireless standards is also an important reason for this dilemma: The mainstream wireless protocols are all formulated by IEEE (American Electrical and Electrical Engineers Institute). Among the three wireless standards recognized by IEEE, IEEE802.11b, IEEE802.11g, and IEEE802.11a, the number of channels is different.
