1. There is a need of selecting the channels for setting up WLANS, to communicate; all the components of a Wi-Fi network must use the same channel. In the Wi-Fi network in infrastructure mode (using an access POINT), it depends on the channel set at the access point.
2. For better results when using Wi-Fi, it is necessary to adjust the channel on the access point as well as configured on the client, to TAKE the least use channel in your neighbourhood.
3. To do this you can use software such as NetStumbler, which will list the neighbourhood Wi-Fi NETWORKS and channels used.

Note:- The channels most frequently used to select one as free as POSSIBLE.

So the recommended channels are as follows:-

Channel 1: 2.412 MHz
Channel 2: 2.417 MHz
Channel 3: 2.422 MHz
Channel 4: 2.427 MHz
Channel 5: 2.432 MHz
Channel 6: 2.437 MHz

You can choose from these channels while setting up the WLANs.
