A 2Wire 2700 HGV BT Business Hub Router Wireless

[LesD]

OK having had a connection rate of 4128 kbs for over 18 days this evening I see this:

DSL  Down  Up
Current Rate:  4320 kbs   448 kbs 
Max Rate:  4320 kbs   1044 kbs 
Current Connection:
Current Noise Margin:  9.0 dB   25.0 dB 
Current Attenuation:  40.9 dB   27.0 dB 
Current Output Power:  19.3 dBm   11.9 dBm 

System Time: Monday, May 5, 2008
09:27:17 PM
GMT Daylight Time
Time Since Last Boot: 19  days  14: 49: 27

In the Event Log I found this:

INF  2008-05-05T09:00:28+01:00  sys:  dsl0: connection lost, reconnecting...
INF  2008-05-05T09:01:07+01:00  sys:  ppp0: connection lost, reconnecting...
INF  2008-05-05T09:01:16+01:00  sys:  ppp0: Up with ipv4 service on pppoa0

What does it mean?

The line was lost for under a minute so nothing serious but I am curious about what it might be.

Certainly my IP Profile is stable and the throughput is good for 9:35 PM:

Test1 comprises of Best Effort Test:  -provides background information.
    IP profile for your line is - 3500 kbps
    DSL connection rate: 448 kbps(UP-STREAM)  4320 kbps(DOWN-STREAM)
    Actual IP throughput achieved during the test was - 3257 kbps

Is this what is seen as the 12 day issue with the single SSID version?


 

[Sebby]

If you held sync for 18 days, it can't be the 12 day issue. Isn't yours a dual SSID anyway?

To be honest, there's probably no explanation as to why your router lost sync; it's not an uncommon occurrence, and anything could have caused it. The good news is that you reconnected at roughly the same sync, so it was just a blip, and certainly nothing to worry about.

[EvilPC]

I've noticed once every 5 - 7 days or so  the SNR and Sync rate on my 2700 (dual SSID) drop to zero.. With in seconds they are back to where they were..

Looking at the logs the DSL connection never drops !!

I'm running routerstat to monitor it, but it keeps happening !

[Rik]

Ah, the wonders of ADSL. Possibly there's just a glitch and the router fails to pick up the stats from the DSLAM, I've seen it, but it's always too brief to try and check it out.

same here, no idea why.

Hi Sebby,

Yes mine is the dual but I was curious about what happens at the 12 day point with the single version.

Seeing this in the Event logL

INF  2008-05-05T09:00:28+01:00  sys:  dsl0: connection lost, reconnecting...
INF  2008-05-05T09:01:07+01:00  sys:  ppp0: connection lost, reconnecting...
INF  2008-05-05T09:01:16+01:00  sys:  ppp0: Up with ipv4 service on pppoa0

I wondered if this was the same sort of line loss or is it a full reboot with the single SSID?

[Sebby]

The router just reboots, Les, which obviously causes the sync to be lost. But that's not what you're seeing - for a start, there's nothing in the log on the single SSID models as the router restarts, so the log is cleared.

Right I see. Thanks for that. 

[LesD]

Well what do you know it's been an gone and done it again at 9-o-clock this morning, pretty much the same time as it did it on Monday! 

In the Event Log I see:
INF  2008-05-07T09:00:12+01:00  sys:  dsl0: connection lost, reconnecting...
INF  2008-05-07T09:00:50+01:00  sys:  ppp0: connection lost, reconnecting...
INF  2008-05-07T09:01:01+01:00  sys:  ppp0: Up with ipv4 service on pppoa0

and now the Stats. show:
DSL  Down  Up
Current Rate:  4544 kbs   448 kbs 
Max Rate:  4544 kbs   1056 kbs 
Current Connection:
Current Noise Margin:  7.0 dB   25.0 dB 
Current Attenuation:  41.0 dB   27.0 dB 
Current Output Power:  19.3 dBm   11.9 dBm 


I would prefer the DSL Down Current Rate to stay below 4544 kbps because I fear instability in the darkness of the evening and a re-synch occuring then would lower my IP Profile based on previous experience. Synching at 4544 kbps at 9:00 is all very well if it will be sustained much later in the day. 

The 7.0 dB Noise Margin is about 2 dB lower than of late too! 

[Sebby]

Can you think of anything that happens at 9am each day that might be triggering this, Les?

If you sync at 4,544k in the day (just enough to get a 4,000k profile) the SNRM is likely to drop a bit at night, though 7dB should be absolutely fine. If it worries you - and given that you're only just able to achieve a 4,000k profile anyway - you might want to force a re-sync at night. Although you'll probably get enough sync for a 3,500k profile only, you should get a 9dB noise margin at worst.

[LesD]

Can you think of anything that happens at 9am each day that might be triggering this, Les?

That's just it I can think of nothing in my house that could be triggering it at 9-o-clock. There is no one in at that time of the morning so there are no PC's running, the heating is off it's really strange.

Another oddity is this appears to be happening on a two day cycle! 

This is what I see in the Event Log today the 9 May.

INF  2008-05-09T08:56:41+01:00  sys:  dsl0: connection lost, reconnecting...
INF  2008-05-09T08:57:06+01:00  sys:  ppp0: connection lost, reconnecting...
INF  2008-05-09T08:57:15+01:00  sys:  ppp0: Up with ipv4 service on pppoa0

The clue was yet another Connection Rate.

DSL                Down  Up
Current Rate:  4512 kbs   448 kbs 
Max Rate:      4512 kbs   1040 kbs 
Current Connection:
Current Noise Margin:    11.0 dB   25.0 dB 
Current Attenuation:     41.1 dB   27.0 dB 
Current Output Power:  19.5 dBm   11.9 dBm 

Having had the same fixed value of 4128 kbps for over 18 days I spot a different one now at 50 paces!

I am wondering if a reboot in the morning might settle things down for another 18 days. What do you think is it worth a try?

[Rik]

It's more likely to settle if you re-sync at night, Les, albeit at a lower speed.

I've been hit by my once 'straight line' Routerstats graph taking periodic hikes down by 1-3db since the warm weather started. Given the timing, I strongly suspect someone is running a noisy air-con unit not too far away. Would this be possible in your case?

An evening re-sync would very likely see my current IP Profile of 3500 kbps go down to 3000 kbps so I am not keen to try this.

Yes I read what you said about this posibility in another thread so I guess something similar is possible in my location but I am not aware of anything that I could point a finger at!   

For now I will just keep monitoring the situation.

[Sebby]

It sounds like one of those problems that will just disappear, but who knows when?

[David]

When you get it, Les, do a factory reset (paperclip in the hole for 20 seconds with the power on, then let it re-boot). Connect it to the PC but not the phone and log into the router interface. See what firmware you are running so that you can decide what you need to do. If you ever want to use the USB interface and don't have the CD, I am sure one of us can help you out.

Just won the same thing paid £7.49.this one is new in box and we have (thanks to Rik) established mine is a dual ssid whatever that is.
I am posting this for both reference and to find if Les had any probs or could give me tip before I get it.

[Sebby]

Good stuff, David. Lots of us - myself included - have dual SSID 2700s. They're a doddle to set up. Have a look at this excellent post, which runs through the process.

[David]

Thanks Sebby,got a hot son who cant sleep here,great link will definatley help me 

[David]

Read through both threads and its making some sense and will give it a go when it arrives.I do see that evrything including manuals are there and none of the parts have even been taken out of the wrappers so gingers crossed,the lady didnt have a clue what it was all about.

I will need some minimal advice when it arrives,tuesday has been promised,it will be interesting to see the results as my speeds since changing phone providers have been excellent. 5.6 down,I cant get any higher on the up than 371.if this improves I will be amazed,the line has proved very stable losing connection only 3 times.I have read so much about these routers just had to try......    

[David]

This is my purchase will or might give an indication of its newness

[Sebby]

It does look new, David (apart from the RJ11 lead, but we won't worry about that!).

Regarding your upload speed, around 380k throughput is the maximum you'll see, so I wouldn't expect too much. If you want faster upload, really you'll need to upgrade to the SuperMax package where you get a higher upload sync.

[Ann]

I didn't find it necessary to put in any code that post linked to above talks about.  I just did the below and also added a password for the router later.

Go to http://home or 192.168.1.254

Click on "Broadband link" at the top and then click on "Advanced settings" link.

Enter your username and password.. Dont click save

While on the same page.. type the following into your address bar..
javascript:document.pagepost.submit()

Once you are connected go to. http://home/tech or 192.168.1.254/tech
Click on DNS Resolve, 4th from bottom on the left.

Add the following...

DNS name: pbthdm.bt.motive.com
IP Address: 10.0.0.0

DNS name: cwmp.cms.smehomehubrms.bt.com
IP Address: 10.0.0.0

DNS name: gateway.cms.smehomehubrms.bt.com
IP Address: 10.0.0.0

DNS name: pbthdm2.bt.motive.com

Thanks Ann there is hope for me yet

Thanks Sebby Im very happy with my speeds I don't think anyone would complain.well some might.my exchange goes 21cn in August and I am not sure what that will mean to me to be honest.
I have no speed issues just thought I would try this   

[Rik]

21CN won't directly affect you until IDNet start offering WBC products, David.

[David]

Thats good.... (like I know what Im talking about
