Any way to get faster broadband (long distance)?

Hey,

I'm on ADSL24 up to 24Mbps (I think they resell entranet which resell BT). I'm quite a long way away from the exchange:

You are approximately 2.87km from the exchange. Note that this is the straight line distance - the actual cable length will be longer!

so of course I didn't expect great internet... but I'm getting 512Kbps (64KB/s) maximum. AOL, TalkTalk, Sky, Tiscali and Orange are the only LLU's enabled in the area, would switching to one of them possibly get me slightly more speed, or am I stuck with really slow internet?

Thanks in advance for any help.

Post your router info. It's a lot easier to determine expected speeds from the attenuation.
 
LLU can sometimes improve the line speed a touch so is worth changing. Sky would probably be the best option.

I'm not actually living at the house at the moment so I can't get the curent stats but these are the router (DSL-2740B) stats from last month:

Statistics Downstream Upstream
Noise Margin 14.7 dB 7.0 dB
Line Attenuation 48.5 dB 31.5 dB
Output Power 12.6 dBm 17.7 dBm

I removed the ring wire from the master socket but it didn't really make any difference.

I would switch to an LLU provider regardless.
 
If you can get the CPW LLU service (Talk Talk) I would recommend dropping a line to Xilo. Their service is second to none. A speed check on the TalkTalk site will give you an idea of what you'll get on that service.

http://community.xilo.net/threads/cpw-opal-broadband-and-phone-packages.836/

Edit; actually you might be able to get on one of their other services with those LLUs you've listed.
 
That noise margin is massive, but yeah, for reference my brother gets around 6mb on a 50gb atten line and as that graph shows you'd be expecting around that for the attenuation you have.

As suggested, switch to an LLU service and you should see improved speeds.
 
Noisy line :mad: LLU will undoubtedly give you more speed but you really should be faster than that already. If you're using the cheap plug in filters the isp sent you consider replacing them with a filtered faceplate (ADSLNation XTE-2005*) and shielded rj11 cable (Belkin). Only costs £15 but makes a surprising difference on long/noisy lines, more so on LLU, compared to the cheap stuff isps hand out for "free".

*if you have extensions you'll need a disposable IDC tool, about 60p.
 
I'd suggest there has been a previous error (or even one still there, although less likely in my experience) on the line that has forced the noise margin up.

FWIW, on my backup line I manage 3776 sync with a 52dB attentuation, but this is with Sky LLU and has involved a lot of tweaking at my request by a very co-operative member of their higher level support team who frequents a popular broadband forum. I can squeeze it to nearly 5mbit with DMT tool, but it drops once a day like this, and is only a backup anyway.

If you can go Sky LLU, I'd certainly try it.

This is the way to go as you should be getttin better. Clean up your internal wiring!
 
Just wanted to bump this topic because I'm in the house now and can get updated stats (the noise margin is even worse, but the sync speed is slightly higher).

I'm already using a filtered faceplate, and I haven't switched to LLU yet.

If the slow speed is due to errors on the line will switching to an LLU service bypass these, or do BT need to fix them? I phoned BT earlier and their response was basically "Your sync speed is within acceptable limits for your distance from the exchange, tough ****"

Should be kicking 5000kbps on ADSLMax with that attenuation I'd have thought.

Your upstream seems high for plain ADSLMax though. Would have thought it'd be more around the 400kbps mark.

Won't be a massive increase on LLU, maybe up towards the 6000 kbps mark if you are lucky.

Your noise margin is incredibly high. ADSL should be stable with a SNR down to low single figures. Unless these figures fluctuate widly I'm guessing that BT have messed up your profile and stuck you on a low connection speed, possibly because of a previous fault somewhere.
 
"Latency type: Fast" means Interleaving is off iirc, This will limit you to a max of around 2.5Mb/s.

Switch to LLU ASAP, If for no other reason than to get away from BT Line Profiles.
 
Im quite far from my exchange and get about 500-800kb/s
Using the small white bt home hub and bt filter.
router stats:

Make anything from that? best way to get more kb's?

This, with a Noise Margin of 20 thats way too higher, it should be around 6 - 7 allowing you to sync much higher, I would speak to your ISP as it looks like your caped. As above it could be because of a fault on the line.

You are certainly a long way from the exchange.

Have you tried the test socket behind your master socket to see if this increases your sync speed? This is presuming you have a modern NE5 faceplate with a test socket.
 
Sorry to bump this topic again but I was just signing up to Sky LLU and they gave an estimated maximum speed of 1.5Mbps, how are they estimating this speed? Everyone seems to think I should get 5-6Mbps at my distance / attenuation but every ISP (even LLU ones) estimate 1.5-2Mbps maximum :confused:.

BT are still refusing to help at all but I'm pretty sure there's a fault somewhere because at the moment I seem to be locked me into a downstream IP profile of 130Kbps (~16KB/s) no matter what speed the router syncs at. The upstream is always maxed though.

That's what happened one morning, and now even though it resyned at 2048 Downstream it's still locked into the 130kbps IP profile.
