To avoid collisions, 802.11 wireless devices use a listen before speaking approach when accessing the wireless medium. Specifically, devices perform a Clear Channel Assessment (CCA) by listening to see if another device is actively transmitting on the channel before attempting to send its own frames. When a device detects another transmission in progress, it will perform a random back-off for a short period of time after which it would perform another check before attempting to transmit again. If the channel is clear after a check, the device can access the channel and send some data.
When neighbouring households start doing this, the "in between" channels get used, BUT your access point cannot see these transmissions as data, but see them as RF interference. . . . so your Wifi no longer negotiates correctly and you lose performance.
Please Help.
Thanks !
I didn't find the right solution from the internet.
