How to prevent electrical spikes coming in through the telephone line
Posted on 2016-08-05
My house or area is prone to lightning strikes. About a year ago my BT router blew after a lightning strike, and the spike coming into the router preceeded to blow the network card from the PC that was connected to it via ethernet.
Fast forward to last month, another thunder storm, and my replacement BT router has blew again. This time, the network card in my PC was fine, however the network card in my Synology NAS blew, as did a standard home telephone, and the base station for another cordless phone that I had. Nightmare.
The old "you must switch off the devices when there is a thunderstorm" advice is no good, because for start it's 2016! Also, I'm at work for 8 hours a day, and asleep for another 8. So I need some sort of protection from this.
Can you recommend anything? I've had a look at an APC device, but this is RJ45 rather than RJ11 so I don't know if it's suitable. Also, some reviewers online report that this thing actually reduces their broadband bandwidth, which of course I'd like to avoid like the plague since we're not on fibre broadband here yet.
I don't understand why these things are not more prevalent to be honest.
Any advice would be appreciated.
