On a client's site, their ADSL modems keep dying (last one was less than 6 months old). It's starting to seem like more than just bad luck. At least one was due to a lightning strike (guessing on the overhead line somewhere, rather than the building). Apparently there was a large flash from the wall socket area and dead modem. This time they recall a recent thunderstorm, so it could be that again.
Could there be a fault with the incoming line (earthing)? Is there a plug in surge/lightning protector device available that is compatible with ADSL? Or is it just a case of replacing the modem every time one dies?
