I had a clients who complained that she can not connect to the internet after a bright flash of lightning struck outside their house that night, another one said the same thing though he wasn't using it and his computer was turned off when that happen.
When i inspected their computers, both clients have the same problem. A damaged LAN card.
Somehow that lightning traveled through the telephone lines and damaged their LAN card even though the other one was turned off.
My advice is, during Electrical Storm you should unplug your LAN cables from your modem to avoid this kind of problem. If you are going out for a trip or vacation, before leaving your homes or offices take time to unplug your cables. Who knows, an Electrical Storm might take place while you are away.
Additional tips when a strom is Approaching:
- Unplug your appliance power cords and cables from outlets
- Lightning can travel through wiring and water pipes, so unplug appliances
- Turn off the air conditioner
- Draw blinds and shades over windows. If windows break due to the wind, the shades will prevent glass
from shattering into your home
- Avoid taking a bath or shower
