Question ethernet cable extension


Distinguished Member
hope this is the right place to ask...

just been over to my dad's to sort out his sky box that had disconnected from the internet....not hard to see why, the end of the ethernet cable connecting the sky box to the modem has had the little plastic clip broken off so it's not holding in place

however, it's not as easy as just replacing the cable as the sky engineer has fed the ethernet cable through the wall from the dining room to living room and put a little grey box on each end leading to the ports

i;ve not seen these before but, if i can source one of the little grey boxes, he'd be sorted as the ethernet cable itself is fine, as is the extension going into the sky box - unfortunately, i don't know what they're called....;)

its like a phone filter....there's a plug to go into the ethernet port, about 6 inches of cable then this little cuboid box which opens up, then you prise up the plastic part inside and it releases the four parts of the ethernet cable itself

anyone any ideas what this is called or where i can source one?

thanks again

Of course if that's what it is there isn't actually any need to use one as you could always just buy some regular RJ45 plugs and a crimper (assuming there is some slack in the cable).

These boxes make it far easier for those unused to terminating cat cable to make a reliable connection without any specialist tools. By the time you've bought a crimping tool, a bag of connectors (and maybe a tester) and then had to redo the terminations several times to get it right then I think the connector linked to above would be by far the best choice and more likely to work first time.
