2wire 2700hg - idiots guide please !

[Inactive]

I have this deal with DodgyDave - timing is everything.

The sad thing is that, for most people, the 2700 has been a start performer. I have to suspect the stock he's got, a sudden rash of problems like this can't be a fluke.

I agree Rik,

Now connected via my Zyxel; =

DOWNSTREAM
noise margin downstream: 17 db
output power upstream: 15 db
attenuation downstream: 9 db

UPSTREAM

noise margin upstream: 22 db
output power downstream: 12 db
attenuation upstream: 5 db


Something seriously wrong with  DodgyDave 2700's

[Rik]

What did you sync at, In?

What did you sync at, In?

Are these the figures Rik, the Zyxel isn't quite as user friendly when it comes to finding anything;

WAN Port Statistics: Link Status: Up Upstream Speed: 448 kbps Downstream Speed: 8128 kbps

[Lance]

Current Attenuation:    63.0 dB (Downstream), 4.0 dB (Upstream)

It seems that is the reason for your poor speed Inactive - the router is massively bumping up your attenuation!

[Rik]

WAN Port Statistics: Link Status: Up Upstream Speed: 448 kbps Downstream Speed: 8128 kbps

Yup, d/s sync is 8128, so your line is fine - the 2700, however, is not.

If you feel like running a BT speed test, you can find out just how badly your profile has been mangled, though I'm hoping blip logic will work in your favour, and recovery will be no more than a few hours.

As Lance says, that difference in d/s attenuation is the key, and is what you should report back to DD.

[Inactive]

OK, many thanks to both you and Lance, and all others that have offered help, I will report the situation to DD, see what he has to say.

[Rik]

Good luck, In.

[Sebby]

I had another email from DD today to say the router has been dispatched. It appears that the replacement is the "V" model. After reading today's posts, I'm a bit concerned it'll be one of the dodgy batch. If it is, I'll stick with my current one, despite the LED problem, as it's working great. 

[Rik]

Keep us posted, Sebby.

[Wingnutz]

OK - tried the firmware flash but has resulted in no change to the software version - still 4.25.19.

Still getting very low sync rate - 544kbps.

Looks like I'll have to wait for the replacement to arrive and hope for better luck.

All I can think now is that somehow the 'innards' of the box are different for our American cousins (box is AA+T badged) and is refusing to talk properly to BT.

Further updates when the new one arrives.

[Rik]

It's entirely possible that one made for the American market won't work over here, Mike. It certainly always used to be an issue in the early days of dial-up modems, with two sets of standards operating. I've never really checked to see whether ADSL is similar, though.

[Wingnutz]

Have asked DigiDave to test any replacement before he sends it to me especially if it is an AA&T badged one. Have made him aware (without yet linking to this forum) that I am aware of other customers receiving slow working modems.

Looks like Dave 'may' have been aware of this problem at the end of last year.

Links to two more with slow sync speeds.

Netgear released different ADSL firmwares for the North American market with their later routers Rik, I wonder if this is the case with 2wire

OK, thanks for the updates, I have a theory, probably a load of tosh, but these are clearly imported from the States, there they run on 110v 2 pin sockets, so DD has provided a substitute mains power block for the UK.

Now my supplied power block is a tiny thing that gets quite warm in use, whereas the original ones with my Zyxel and BT Voyager are huge in comparison, and run almost cold.  I was just wondering if these are outputting the correct and stable voltage?...and if not, could this have detrimental effect.?


Readings from supplied power brick;  Output +5V====2.0A : Output Power 10W max.


Any thoughts??

Speeds recovering ..thankfully. ( using Zyxel ).

when you say tiny can you provide a picture, mine is quiet chunky, not as big as my Netgear by any means but its not small its maybe 2.5" wide 4" long (guessing here as I look down at it) and it has a label on the end that plugs into the router, alas I cant give you the specs on it as I can't get to it, maybe Xild can or Rik. 

[Wingnutz]

My supply is 5v 2A. 2wire modem states 5.1v 2A

A close match I  suppose.

Hi Gary, this power brick is not much bigger than a standard 13a plug, only 2" deep, at it's deepest ( front to back ) point, otherwise about the same as a standard plug, it just doesn't look up to the job to me.

I am clutching at straws here, I just cannot fathom why it works, uses the same software as others, yet gives these dire results.

My speeds have now fully recovered, thank gawd..

Using Zyxel;

Thats not how big mine is Inactive but it could be different power supplies for the older routers, mine is quite big and no where the size of a 13amp plug, not a lot of use without specs but that would mean turning my router off to look 

[Rik]

Mine's about 2x3x1" - can't see a voltage rating without unplugging it.

[Inactive]

OK, this thing is nowhere near that size, perhaps somebody that has a spare one may be able to give the spec.

Thanks..

In' see my post about 6 above this one. Spec's from my supply and the 2700hg box.

Mike

[Inactive]

Yes Mike, thanks.

My main concern is the tiny physical size of this one that is supplied, all of my other routers, Zyxel, BT Voyager and Talk Talk aka Philips all have large power bricks, obviously for a reason.

I was just wondering if this tiny power brick is up to the job, as I said, clutching at straws here.
