Im with you, so sometimes at longer distances it makes sense to be on ADSL1. Interesting stuff. Cant see me getting more than 4meg anyway.

I dont see why not you should be syncing just over 4.0Mb on ADSl2+ if all was good according to kitz, so your a little under for that, being on ADSL1 should get you a little more still at least near 5Mb so something still not right.

Cool, Im going to have another play about with it tonight when I get in.

I'll try disconnecting all the other unused extensions first and see if that helps.

In reply to a post by MrSaffron:

Never seen a line with G.992.1 (ADSL) go over the 8Meg mark.

No, but I was talking about the standard itself. In UK it is limited to 8 Meg for some reason. Use ADSL2 if you want up to 12 Meg (but no use to OP).

This is the back of the main extension in the living room.

All the others are exactly the same apart from one which was like this:

So I swopped the wires so they were matching, this one above is the closest to the xnte but as people have pointed out, maybe not the first wired.

Sorry for the delay, I've just managed to review the pictures and the other posts to this thread. As XRay & Mr Saffron have covered the sync speed, protocols and statistics, I'll just concentrate on the wiring.

Yes, as expected, you have suffered from a construction site electrician's botch. Notice how the insulation on every wire has been stripped back, the cores twisted together and then forced into the IDC connectors? All in all, a big fat zero and a fail!

Where exactly do you wish to site the modem/router? (Edit: In the lounge, as I now see.)

I note from your later comments that you do not have, nor wish to have, a telephone connected to that circuit and it is only used to provide a broadband signal. In that case, this is what I would do --

(1) Remove the yellow plug in the XNTE to isolate the internal wiring.

(2) At each socket upstairs, disconnect the socket, snip off the exposed copper core of the wires that were connected, coil the wires neatly into the backing box and fit a blanking plate over the backing box.

(3) In the hall remove the socket and separate the two cables. Choose one and (temporarily) connect the blue/white stripe to IDC2 and the while/blue stripe to IDC5 of the socket. Plug a telephone into that socket and re-insert the yellow plug in the XNTE. Check to see if the phone is live. If so, mark the cable as the incoming supply from the XNTE. If not, check the other cable.

(4) Remove the yellow isolator plug, once again. Now, with freshly trimmed wires from both cables, fit gel-crimps to join the like to like wires of the blue pairs in each cable. That is blue/white stripe to blue/white stripe and white/blue stripe to white/blue stripe. Fit a blanking plate over the backing box.

(5) In the lounge, remove the socket and separate the two cables. Do the same test as you performed in the hall to identify the incoming cable. Having marked the incoming cable trim off all old exposed copper cores. Neatly coil the cable which supplies the feed to upstairs into the back of the box. From the incoming cable, connect the blue/white striped wire to the terminal marked "B" and the white/blue striped wire to the terminal marked "A" of your newly purchased NTE5/A. Fit the back plate of the NTE5/A to the backing box, plug a telephone into the test socket and re-insert the yellow isolator plug into the XNTE. Confirm the circuit is live.

(6) Finally, fit the newly purchased ADSL filtered faceplate to the NTE5/A. Make a final check by plugging the telephone into the front phone socket.

(7) Connect up your modem/router and allow it to sync. Call your ISP, explain that you have had your poor internal wiring rationalised and ask if they will perform a full reset on your line, starting with a new training period, as if it was a new service provide.

Your shopping list.

Three white blanking plates. (Any electrical retailer.)
Two gel-crimps. (Probably have to purchase a small pack from Amazon, for example.)
One NTE5/A. (From Clarity, for example.)
One ADSL filtered faceplate. (From Clarity, for example.)

ANSI DMT Modulatoin and G992.1 8Mps downstream, 1.2Mbps upstream.
There is a S=1/2 line coding that with G.992.1 can yield 12Mbps, but ADSL2 G.992.3 took over circa 2002

A tendecy to take more notice of those than wiki's.

Like you, a2hgo, I'm a newbie & a non-techie. I'm not even sure how to obtain stats. I've been with O2 for a few years & I've been very satisfied until recently. I live in a low-speed area & was accustomed to speeds of 1.8 - 2.4 meg even at peak times.

Although I still achieve speeds up to 2.4 meg off-peak I'm now lucky to reach 1.0 meg at busy periods. On Sat & Sun evenings my speed dropped to 0.3 meg & averaged about 0.5 meg.

On Sat I was asked by 2nd Level Tech Support at O2 to monitor my speeds for a day or two in order to establish whether my low speeds were caused by a technical problem or by volume of traffic. They said I would need to speak with Customer Services if the latter proved to be the cause. I'm not sure why.

Could you please advise whether your low speeds are also occurring at peak times. I accept that speeds will reduce during evenings & weekends but a drop from 2.4 to 0.3 seems intolerable.

Could it be that O2, at least in some areas, just don't have the equipment to handle their increasing customer base. I'd like to know if it would be possible, prior to moving to a new ISP, to establish how many other people a user would have to share with. I think it's called a contention ratio.

My broadband speed of 0.3 to 2.4 meg seems absurd considering that I live 2 miles from the city centre of Wakefield in industrial West Yorkshire. My heart goes out to those who don't have much hope of ever going faster than about 2 meg. I think my local exchange, Sandal, is to be upgraded to FTTC next year but I don't know how I'll be affected personally.

You should be able to get the router line stats using the info from this link to the KITZ website.

Don't apologise burakkucat, your help is appreciated.

Had all the faceplates off the sockets tonight. I've disconnected the upstairs ones end established the socket in the hall is the first from the XNTE.

Just out of interest I wired a faceplate with a short length of wire directly to the customer side of the XNTE and plugged the router in. Quickly went into the stats and it was syncing at 6meg!!!!!

Anyway, at the fist socket it's now syncing at just over 4meg. When I connect the wires together in this first socket and use the socket in the lounge it drops further to around 2.8meg. So I've decided to relocate the router to the hallway. Only problem wit this is that I can't plug the Ethernet in for my xbox and Internet TV without running it across the living room floor.

I'd be interested to know if it would be possible to run a new length of external cable directly from the XNTE, across the front of the property and into the living room through the hole currently also used for the sky dish and into the existing socket in that corner of the lounge. I could then replace this socket with an NTE5 and Ssfp. Effectively being a direct feed from the XNTE and perhaps achieving the 6meg speeds I got when trialled and meaning the router will be back in the lounge so I can plug all my stuff in.

1_4_all, I feel my problems are mainly wiring related as opposed to ISP as by messing with the wiring I've got it from 1mb to 4mb.
