Explanation

Traditional cordless phones (particularly 2.4GHz DECT phones) and older cordless phones operating on the 2.4GHz band share the same radio frequency spectrum as 802.11b/g/n Wi-Fi networks. When the phone rings or is in use, it transmits on the 2.4GHz band and causes RF interference with the wireless router, resulting in dropped connections. The solution is to change the Wi-Fi router to the 5GHz band (if the hardware supports dual-band 802.11n/ac/ax), which is completely separate from the frequency the phone uses. Alternatively, switching to a 5.8GHz or DECT 6.0 cordless phone would also eliminate the conflict. Moving the access point closer (A) does not eliminate the interference. Removing the phone (B) is impractical. Changing wireless security encryption settings (D) has no effect on RF interference between devices.
