Request For Summary of Commissioning Steps for Single SSID 2-Wire 2700 Router

[Ted]

I have to say i know what you mean Les, i'm going into 2wire overload

As far as i'm aware the wireless isn't disabled in any of the Firmwares. On the contrary the output is boosted on both SBC and Singtel Firmwares. You may be thinking of Voip, which doesn't work with the SBC FW.

I believe that FW 5.29.107.12 is available for reverting to BT FW but i'd have to confirm that.

The highest BT  firmware available for reverting is 5.29.107.12 and you can download it from my site here

Hi Alan,

Thanks for the link to your site.

I have just re-checked mine and it is 19. This is a copy and pasted form the Simmary page:

Current Software: 5.29.107.19

So I guess this means I cannot get back to this version!

Hi Ian,

You can probably write one for yourself by now  but seeing the title of your thread was the catalyst for me to write down what I did to set up my Single SSID 2Wire 2700HVG's.

At post no. 35 is my contribution the the thread Rik started here:

Dear All,

When I last contributed to this thread (mid-June), I indicated that I would report later on my installation and performance of a 2700HGV (single SSID) modem/router. To be brief, progress has been disappointing, and it is fair to say that my former modem has given me superior long term throughput than what I have achieved so far with this device.

To summarise, I went along the 2700HGV route on the basis of having read several reports that this device performed particularly well on long lines - my line has a reported loss of 61.5 dB. For example, on 05 June, Roger P in reply #18 to the thread "Outage" reports a DSL rate of 2272 Kbit/s on a line having attenuation of 61.2 dB; similarly, johnny5 in reply #27 to the thread "Leaving BT" reports a DSL rate of 2624 Kbit/s on a line having a loss of 62.0 dB. Today I am able to report (using the BT Speedtester) a DSL rate of 1056 Kbit/s, and a IP Profile of 750 Kbit/s, with a throughput of 671 Kbit/s!!! My modem router has been powered up for over 5 days, and the log does not report a single loss of signal or re-connection.

The reason for the passage of time since my last contribution is that I have been in frequent contact with the IDNet help team, and, on their suggestion I have been in contact with BT directly. The IDNet team have had my line tested by BT on more than one occasion, and they have not identified any abnormality. Similarly, BT have reported to me that they tested my line on two occasions, and that did not throw up any concern. I have also used the BT "Quiet Line Test", and I have not been able to discern any white or impulsive noise.

I have implemented a number of changes to my own  home circuit - largely on the basis of recommendations in this forum:
1. I purchased and installed an ADSL adaptor on to the lower half of my master socket.
2. I made provision for mains power in the vicinity of the master socket, so that the modem/router could be permanently located there. (My previous modem/router only had Ethernet connections, so had to be located close to my computing equipment - it was connected to an extension socket (all ring wires removed), and still managed to out-perform the 2700HGV!).
3. The most recent change was to use a length of screened cable to feed the modem from the ADSL socket on the lower half of my new ADSL adaptor - the 5 days I refer to above is since the fitting of this cable.

I can confirm that I have implemented the DNS poisoning procedure described by Rik. I have also implemented the steps recommended in the note by Alan Woodward. I am still using the firmware supplied with my 2700HGV (4.25.33), and have not so far been tempted into using either the Sigtel or SBC firmware.

I have noticed numerous entries to two of the Logs maintained by the machine:
1. Troubleshooting - Event Log
Something like 150 entries per hour of the type:

fw,fwmon : src=91.144.x.x dst 91.135..3.114 ipprot=6
Sport=2628 dport=2967 Unknown inbound session stopped

fw,fwmon : src=24.64.x.x dst=91.135.3.114 ipport=17
Sport=13640 dport=1028 UDP Port Scan detected

(the x.x above replaces part of the IP address that varies from appearance to appearance, the other parts seem to be fixed)

2. Advanced - Detailed Log:
httpc_poll_dispatch - Connection timed out

This entry occurs hundreds of times throughout a 24 hour period!

Finally, I am sorry that my observations have led to such a long note, but I hope that something might ring a few bells with someone, and point to a precaution I ought to have taken, or indeed, point to an oversight on my part. At the moment I am seriously considering placing my old modem router adjacent to my master socket, and running a long Ethernet cable for a few days!

Many thanks in advance for any further suggestions.

Ian.

I'm sorry that you've been disappointed with this router. An incorrect profile suggests instability, but you say the router hasn't lost sync (though the reporting is a bit odd on 2700s).

I can only think that you may have a local noise source. A de-tuned AM radio may help you locate it. Otherwise, you've really tried everything.

What sort of sync did you achieve with your last router, out of interest?

[kinmel]

You seem to have covered all the usual bases.

I assume your SNR is 6dB, but for some reason your 2700 doesn't suit your phone line and is probably best abandoned  

Using any of 3 Dual SSID 2700s; on my line currently I get 4288+ sync for an attenuation of 60.1 at 6dB SNR, while other makes of router get about 3000 sync on this line.

The Singtel firmware will definitely perform worse, it targets a SNR of 8dB.

The Log is merely reporting firewall monitoring events and is normal.

Just like you and explained by Alan I get entries galore of this form in my Event Log:

and an equal multitude of these in the Detailed Log

Initially I was concerned about the ever increasing number of such entries especially reading about the 12 day/300 hour reboot issue with the SBC software. I have a single SSID 2700 with BT Current Software: 5.29.107.19 and although I do see occasional re-synchs and even rarer reboots I have just had a reboot between Noon and 1 PM today. This was after 30 days plus since the last one.

Like you I read that 2Wire 2700's did give better results on poorer lines and for me I did see a 500 kbps improvement in my IP Profile over what I had with my Netgear DG834 (mk1). I also read that this was not always the case but at the price I got mine for on eBay I felt it was worth a try.

I am sorry that it does not appear to have worked out for you.

One other thing the good folks on this forum helped me sort out early on was an electrically noisy PSU in my very PC that actually caused my Netgear router to drop the ADSL line as the PC booted up! This was a new one from Micro Direct just before last Christmas. I now have a much more expensive Tagan one that is doing the job very nicely thanks to a nudge in the right direction from Rik!

The AM transistor radio out of tune on the Medium Wave helped me to track it down and also to show me the interference any number of my "Wall Wart/Soap on a Rope" PSU were generating so I have made sure that these are physically as far away from my router as I can sensibly get them.

I hope things improve for you! It is just a pity that after all you efforts have not been rewarded with success.
