Question broken ethernet

[phil george]

an engineer plugged in an old ethernet cable that was liying behind my tv, the cable was actually cut and was inside the wall cavity but hed plugged it into the router and the router lights were flashing, could this have been causing an issue and could it have caused any damage?
thanks

Sounds like a very clueless 'engineer'.

Does the system work after removing this cable?
If so, no damage done.
If not....

thankyou, well its working now but since he came out ive been experiencing bb dropouts, i was just disconnected from an irace and the router reset itself so i had a look and found a 3rd cable that shouldnt have been there. so im wondering if a cable that was cut off but plugged in causing the connection lights to flash could have been causing a connection issue? ie the router was trying to send out signals to a dead end?.....NOOB.

Sounds like you need someone actually competent to diagnose all the wiring in your house.

Not some 'engineer' that plugs in a random cable without knowing what it is or is not connected to.

id usually check everything after them but i was busy. you would expect an eng to at least ask or only plug things back in that were plugged in before? no?.......but do you know if a severed cable could cause connection issues?

You would 'expect', yes.
But there are many many clueless people out there, faking it.

No, the router should not be trying to do anything with a cable that is not connected to anything on the other end.

so a cut off cable wouldnt cause the internet to discon.?

A clean cut, no. That is no different than a properly terminated cable, that is not connected to something.

But, a 'bad cut' may involve one or more bare wires touching.
Which could introduce all sorts of weirdness.


Disconnect any cables that are not actually connected to a PC.

all look pretty clean, i was hoping id found my connection issue but as we were speaking half an hour ago, it dropped out again!!
