wireless routers have liberated computers from restrictive ethernet cable connections, but they’re not completely problem-free.like any radio communication technology,WiFi is affected by interference from other devices,which can result in reduced data transfer speeds poor network range and dropped connections.

The problem is that a host of other wireless devices also use this frequency and it’s pretty congested as a result.Baby monitors, DECT cordless phones ,Bluetooth headsets and other wireless PC peripherals all use the 2.4GHz part of the radio spectrum, with a WiFi signal.
