2700 DSL connection problem

KeG123 · Jan 25, 2011, 19:18:21

Would appreciate some help if poss

Just received a 2700 (second hand, ebay) with a view to experimenting and squeezing out as much as possible from my long line (5k, Att 63.5db). My ISP is BT. My Netgear router manages 750K down and 310K up and hasn't lost the connection in the three weeks I've had it (until I unplugged it to try the 2Wire

)

Followed the excellent guides on this forum and reset the modem and accessed the set up wizard. Unfortunately I get the 'unable to detect DSL signal' message.

My Netgear 3300 has no problem detecting and syncing - do I have a faulty 2700 ?

Hi and welcome to the forum.

You certainly may have. Is there another line you could try it on, to see if the same thing happens? Have you tried using a different cable between router and phone socket?

KeG123 · Jan 25, 2011, 19:26:51

Hi Rik

I've used the same cable used by the Netgear so I know the cable and connection to my BT IPlate is fine.

The DSL connection green light on the 2700 flashes with or without the DSL cable plugged in.

Just wondering if I was doing something wrong before I try and get it exchanged

pctech · Jan 25, 2011, 21:36:08

IF DSL is flashing without the cable to the phone jack being in its definitely a dud.

KeG123 · Jan 25, 2011, 23:42:21

should have got a new one

Polchraine · Jan 26, 2011, 10:05:23

Return it to the seller for a full refund. Unless they sold it as faulty you have every good reason to return it and if they refuse raise a dispute.

Have you tried the one that came with the 2700 ?
Some RJ11 connectors use the 2 inner pins whilst other use the outer 2, although I must say I thought the 2700 could detect the DSL on either pair...

Thanks for the suggestion but its all packed up and ready to be posted back to the seller.

Yes, I read that the 2700 should look for inner and outer pins and you will hear a relay clicking whilst it does that. I didnt hear any clicking so maybe that was the problem

MisterW · Jan 26, 2011, 18:40:28

Yes, you should definitely hear a relay click during the startup, if that's not happening I suspect it IS a faulty unit.

Rik · Jan 26, 2011, 18:43:04

Of course, you have to add eventually, given the 2700s speed of booting.

Just got my replacement

Excellent results

For those struggling with long lines (to the exchange) just wanted to share the results of replacing my Netgear router with a 2Wire 2700

BEFORE

ADSL Link   Downstream   Upstream
Connection Speed   960 kbps   448 kbps
Line Attenuation   63.5 db   31.5 db
Noise Margin   6.3 db   12.0 db

AFTER

Down Up
Rate:   1248 kbs   448 kbs
Max Rate:   1248 kbs   684 kbs
Noise Margin:   6.0 dB   13.0 dB
Attenuation:   63.0 dB   31.5 dB
Output Power:   16.2 dBm   11.9 dBm

Still have a download of 750K but hoping for better over the next few days of the settling in period, but ping time has reduced right down to 35ms already.

Well chuffed

Glenn · Feb 04, 2011, 11:19:00

On my long line last week, a Speedtouch 585 v6 was sync'ing around 2880, swapping it for my 2700 v6, gives me 3392, 32k below a 3m profile.

Rik · Feb 04, 2011, 11:20:45

BT's arbitrary limits are so frustrating.

Welcome to the 2700 fan club.

Turned off my 2700 ! Well, actually turned it into a WAP along with the other two.

It's been part replaced with a product that is totally user unfriendly called Huawei and the other part is a 2701.

I wonder if 2wire will develop a VDSL modem and router?

I still have one connected in my Scottish location - has not been rebooted or even lost sync for nearly 6 months.

MisterW · Feb 04, 2011, 14:50:53

Yes, but you'll not be able to get them on ebay for a while.

Glenn · Feb 04, 2011, 15:30:59

Are 2Wire keeping their name, or being rebranded to Pace?

Rik · Feb 04, 2011, 15:35:22

Interesting point, Glenn.

MisterW · Feb 04, 2011, 15:47:45

Probably doesn't matter too much since all of their stuff is rebadged to some extent by the ISP's through which they sell, as in BT Business Hub.

KeG123 · Feb 05, 2011, 11:54:59

Download still at around 740K so I guess IP profile is still 750K (cant check, BT tester playing up at the mo)

Looks like we had a power cut in the night (which we do occasionally in bad weather out in the sticks

), so that hasn't helped.At least 2700 re-synced 1248

Rik · Feb 05, 2011, 12:01:46

Your profile should rise to 1M if you can hold that speed. I'd suggest you consider putting the router on an uninterruptible power supply, it can help in many ways.

It will probably take five days to change I'm afraid.

KeG123 · Feb 08, 2011, 19:20:29

The thing is,when I get the UPS I'll have to unplug, reconnect etc

Rik · Feb 08, 2011, 19:21:49

You will. Plug the UPS into the mains first for 12-24 hours before you make the move.

KeG123 · Feb 08, 2011, 19:45:00

Training data looks good to me so far - am I right ?

Lance · Feb 08, 2011, 22:34:27

The margin looks good at 6db so hopefully the line will remain solid.

Aaron · Feb 08, 2011, 22:58:29

Sorry to barge in, but what's a good cheap UPS for a router only? I have an APC UPS already for the PC, but that's at the other end of the room and getting a 2nd one of those is a bit OTT and costly.

Rik · Feb 09, 2011, 09:57:03

It will stop the router dropping out due to mains fluctuations, Keg reported that he's subject to occasional cuts.

Polchraine · Feb 09, 2011, 10:41:00

Thoughts about using a UPS for the modem and router.

UPSs use a switched mode power supply (SMPS) to charge the battery or capacitor bank and when power goes off a second SMPS which is normally idle switched in to provide the required mains output - some UPSs will always provide the output from the second SMPS.

Given there are two noisy devices close by, how much shielding is around the case to stop noise? It could have an adverse effect on the noise level in the received signal causing degradation and lowering of sync speed.

They will claim the output is sine wave - but they are often a set of discreet levels which approximate to a sine wave - smoothing will clean it up a little but when the non-sinusoidal supply hits the power block for the modem/router it can again have an adverse effect causing local noise.

Rik · Feb 09, 2011, 10:42:46

It works for me.

KeG123 · Feb 09, 2011, 19:18:35

I went for this one

Rik · Feb 09, 2011, 19:20:29

That should be fine against power cuts.

You can check the current profile for your line by logging into your AAISP Broadband Control Panel and the current profile is displayed next to your phone number on the line highlighted in green.

If you click on your phone number, you move to the line diagnostics page and can read off any automated profile changes, such as 27 Jan 04:32:07 BRAS 4M/828K to 4½M/828K, Opt In, 2011-01-26 03:1... -BT-

Although you can turn interleaving on/off, and change many other line management options yourself in the panel, touch nothing until your 10 day training period is complete.

Not a problem, but for a split second I got very excited thinking I could tweak my own connection

Profile still at 750K so I guess its stuck

At least it will make a change asking for a 750 stuck profile to be fixed rather than my (previously) normal 135

lozcart · Feb 11, 2011, 17:59:55

I'm sure my profile only shows a change on the BT speedtest if I force the router to reconnect.

Rik · Feb 11, 2011, 18:00:36

Leave it till the morning, then force a re-sync (time to put the UPS into use). That may force the change.

Gonna take some effort to sort this out now
