Wifi disconnection often occurs as a result of one or more of the following causes: 1. Weak wifi signal - when you get to your home or office, make sure that you are in an area where the wifi signal is strong (and preferably near the router). A weak signal can lead to disruptions and interference. These interruptions cause a loss of connectivity and possible data loss. 2. Other wireless devices using the same frequency - if there are other wireless devices using the same frequency as your router at home or office, make sure to switch them off (especially laptops, tablets and mobile phones). 3. Congestion - too many people using wifi at the same time can lead to congestion and data loss. 4. Low battery - if your laptop or mobile phone has a low battery, then it will not be able to communicate properly with the router. This causes loss of connectivity and data loss. 5. Nearby radio transmitters - if there are nearby radio transmitters (i.e microwave oven, cordless phone or other wireless devices), then your wifi can get disrupted. 6. Old or faulty hardware - if your wifi router or any of your other wireless hardware is old or faulty, then it might be causing interference that disrupts the connectivity. 7. Incompatible drivers - sometimes, your wifi adapter or other wireless card might be incompatible with the system. This can cause unintended loss of data and connectivity issues. 8. Physical obstructions - if there are physical obstacles between your router and your laptop or mobile phone (especially walls, metal or concrete), then this can disrupt the reception of wifi signals causing connectivity problems and data loss. 9.
