Ethernet cable installation issues

Go to solution

hi

I have success fully run the broadband signal from master socket to Bt home hub 6 using one of the twisted pairs of an ethernet cable

I now want to run ethernet back from hub to where master socket is using only 2 of the pairs in the ethernet cable

I did this using one pair on 1 and 2 and another pair on pins 3 and 6 and using a cable tester i can confirm that pins 1,2,3 and 6 are directly connected.

So my question is does the home hub 6 support 2 pair (4 wire ethernet) or have i done something wrong

 

I know that the port on the hub works as i have tested with a normal ethernet cable plugged into the port

i would rather not have this ethernet connection then move my hub to the master socket

Thanks

I assume that is a typo and you mean 6

The Ethernet ports are GbE but should work at 100M with 4 wires but can't confirm 100% that they will. Did you restrict whatever device you connected to 100M?

Select your NIC in Network Connections then click on configure then advanced tab. Select 100M full duplex.

unfortunately selecting 100M full duplex didn't work

I have a SH2 hub and I've just butchered an Ethernet lead and it works fine with just 1,2,3 and 6 connected. That's without changing the NIC from auto negotiation.

so i used a cheap cable cutting wires 4,5,7,8 and it still worked with the bthub

I tired putting the broadband signal on a separate cable thinking that it might be causing interference but no luck so my guess is that i have just exceeded the max length for 2 pair ethernet even through my run is only 5m

Thanks for your help though

Are you sure the plugs are properly crimped?  It should work fine for 100M

I got it working the first time I had crimped it badly but I thought it was I problem at the keystone so I repeatly punched down those cables which damaged them I then recrimped the other end properly but now the damage cables didn't work which is when I posted my problem so I just cut them back and soldered/ extended them and now it works.          

Thanks for your help
