eFibre Installed extension cable speed slowed

jaffusmax

Hi

A bit of advice please, I had to move my eFibre modem from the front door due to a very poor signal around the house to the kitchen. I ran a 25M line to the modem from the socket.

Now my speed over ethernet/wifi has near halved from 48mb down 10mb up to 25mb down 5mb up. I am getting a much better signal but at the expense of speed.

How would a remedy this also bear in mind I got the cable from woodies?

You used phone cable. D'oh.

Go buy CAT6 cable. That will only lose a tiny amount.

In my defense it said Broadband Cable and also my Wife picked it up for me!

Also it is the RJ111 plug head one I need? Is a Cat 6 a typical ethernet cable?

Cat 6 is future proofing it but if you can't get that then Cat 5/Cat 5e will do just fine.

I have Cat 5 wired all over my house and it easily saturates my 100/20 connection.

Yep, CAT6 is typically RJ45 terminated for ethernet. This is what you want. The left side of the eircom NTU(socket) is actually an RJ45 female despite connecting to a phone line. See image below how its just a small bit wider. The reason to use network cable here instead of phone is the quality and twisting is much better. This means theres much less loss/interference. VDSL is very distance sensitive but you are a few hundred meters from the cab already, so 10-15m more good cable should have a very small effect.

Thx very much all is clear, i did not realize the NTU also took RJ45 cables.

Just one thing now do i need adapter to plug the cable into the efibre f1000 modem

Sorry to hijack your thread but if I get a length of cat6 and use the left socket of the NTU do I then connect it to the WAN port of the router? Will the router connect?

No. You connect it to the DSL port. Its still a VDSL signal coming in, not Ethernet(WAN-DHCP or other). In fact the modem will only use 1 of 4 pairs, but thats all it needs to its thing.

****, forgot about that before. The F1000 wont accept the RJ45 in the DSL port. Dumb mistake on my part. So you'll have to crimp one or both ends down to RJ11. You could use an adapter but that'd add some loss.

Personally I have the tools to hand so it didnt occur to me but for yourselves if you dont own an RJ11 crimp tool I'd try and see if you can buy some good cable pre terminated.

I won't go near it at all. The kn guy did a very neat job and I get 31-32meg of my available 34meg so I don't think cat6 cable instead of what's there now will make any difference.

I think i will run a cat6 to a spare router i have and try and use it as an ethetnet hub linking it to the modem

If that's feasible in your house its always the ideal situation.

Ill do this first and if there is a big drop in speed ill get a crimping tool. I just built my own pc so i feel confident i can crimp a cable. Thx again for the advice if i lay a cat 6 its a good start anyways.

Just a quick update.

Ì just went and bought TP Link Powerline sockest for 30euro in PC World and turned my old Linksys Wrtg Router into a LAN Switch. Here are the results

if you need to use a 25m cable its best use a dsl rated cable or a shielded cat 5 cable with rj11 connectors not a cheap phoneline ext cable.
