I have an external wireless modem with a broadband internet connection in my house. My desktop is connected through LAN cable to the modem while my laptops connect through wireless connection in my house. My home telephone line is connected to my external wireless modem through an ADSL splitter.
The public telephone cables are hung from pole to pole from the distribution point to my house. Whenever a lightning strikes in my neighborhood, a power surge occurs on the telephone line and always without fail damages my modem.
However my normal landline telephones still function properly even after a lightning strike. All other electrical appliances including my computer are unaffected after lightning strikes as all the power output in my house is protected by fuse.
Hence the problem is that whenever a lightning strikes, a power surge occurs exclusively on the unprotected telephone line causing damage to my modem.
I know that the best solution is to physically disconnect the telephone line from my modem after every time i use the internet. However i would like to know whether is there any other solution to this problem ?
Is there anything else that i can do such as fixing a lightning surge protector for my telephone line in my house before it reaches the modem ? My house is already equipped with a lightning protection rod on the roof but this only serves to protect the electrical power supply and not the telephone line as the telephone cables outside my house are hung from pole to pole over large distances and is vulnerable to accumulating charges/voltages during lightning strikes.
Is there any good reliable lightning protection device that i can install for my modem and/or telephone line ?
