static buildup on a wire causes modem to drop connection?

Recommended Posts

My DSL modem dropped internet connection today so I called AT&T technical support. One of the tasks he asked me to perform was to unplug the wire from the wall jack and modem, turn it end-for-end, and plug it back in. He said after several years of use, the wire can build up a static charge. Any MythBusters in the house?

That makes a heck-of-a lot more sense. I kept asking him, are you serious? Static accumulates in the wire? He said to turn it around and it will reverse the static. I don't know if this is an official AT&T procedure or not. I suppose if you reverse the cable then you will knock off some of the corrosion, but it would have been easier to unplug and replug each end.

I know in space (satellites) this can actually happen...depends on the resistivity of the material. In some orbits/cases additional shielding is provided over the wire insulation to prevent it from getting charged. Wires that are not connected can build up charge and actually discharge/arc. I mention this just because it is kind of interesting.

 

ESD containers are not made of perfectly insulating material, so they will not hold a charge.

 

I don't think that's what is going on here though...reversing the static does not make sense...

 

Just the act of touching the wire would dissipate any possible charge.
