Improved Attenuation/Internet Connection

I've done a bit of research and found out it's better to use a long lan cable rather than a 15 metre telephone extension lead. Would I notice any difference, I'll probably be looking for a 10-15 metre lan cable. Will it lower my attenuation and by how much if possible? Some ISP showed after and before results using an extension lead and a lan cable, the attenuation was cut in half from 42.5 to 22.5. Also what kind of prices can I expect from high streets?

My exchange is 300 metres away from me, my attenuation up/down is 25/15.2

Thanks all.

Remove the ring wire from your master socket. You'll see more benefit.

Okay I have no idea what that is lol. Also what is the point of putting plug into the test socket?

wouldn't the removal of your ring wire cause a bit of incontinence?

Google it, there's a photo guide somewhere. From memory its like a loopback that allows your phone to ring, which isn't needed with a microfilter. I removed mine and saw about a 15Db improvement.

Plugging it in to the test socket eliminates the possibility of the problem being caused by internal wiring or a faulty secondary socket.

15DB! Improvement that's crazy good lol. What if I just used the old long lan cable instead of an extension lead would I see any difference? Any ideas?

have a look … have a look here:http://www.jarviser.co.uk/jarviser/broadbandspeed.htmlandhttp://www.jarviser.co.uk/jarviser/bellwirenutshell.html



Thanks man, got a question for ya. Does removing the 'bell wire' cause improved attenuation or just higher up/down speed, Im already at my max I got 8meg broadband, speedtest.net shows my download speed as 9.50. So looking at it like this I wouldn't really benefit would I, since I'm being capped at 8. But if it improves line attenuation then that'd be great as I'm looking to go for 24 mb, if I can get within the 20mb mark. By the way the building I live in is 3 years old. Could it mean I might not possibly have to remove this 'old wire' or age of socket doesn't matter?

Ethernet is cheapest from ebay, I think it's worth doing. Also join the forums and get your profile tweaked, I got my speed on ADSL2+ improved from 12 meg to 18meg just from that.



Interesting, thanks for that.

the bell wire can act as an RF receiver and cause interference; it was originally there as an anti-bell tinkle wire (when dialling, other extensions would tinkle in synch with dialled digits) these days it's not required, so take it off

Thanks, will try, hopefully I don't kill the phone/broadband line or I'm dead.

So a wireless signal isn't recommended?

I'd hope not...

hard-wired will always be better than wireless, due to external factors affecting the wireless signal

Good, im staying wired than.

I also find wired more stable. Depends on the use, for anything other than downloading the speed won't really matter.



Hmm okay, looks like wired is for me, hey by the way is it possible for you to tell me your line attenuation and your noise margins?

I can, but not till I'm home tomorrow evening.



Okay thanks man appreciate it, will wait until than, just wanted to compare our attenuation and noise margins, so I can approximate what kind of speeds I would be getting. Thank's again dcx.

Yes, if it's only three years old it could well be properly filtered or missing entirely.

As for the ethernet vs. extension why not test it yourself? The network comes after the attenuation bit so it won't make any difference to that so the attenuation you get when plugging the router directly into the socket stays the same regardless of whether your home network is the worst wifi or the best gigabit ethernet.

I haven't noticed any difference using the telephone extension cable on my speeds (which are 7.6Mbps) but I haven't really tested it.

Alright thanks for the info, reason I make many is, because once one it is dropped of the first page, no one goes back to look at it especially when it comes to a question that actually requires thinking power than the usual "what did you do last night", "my day was hell", "what should I get my oh", get it?

Just bump the last thread? And here:



Your attenuation is very close to mine, mine is 24 and my snr is around 6. Yet you get much better download speeds than me. I get max without extension lead 15k with extension 12k. They must have fibre optic round your area haha.
