Hi guys,
I am looking for a new router to hold a connection at low SNR. I am looking to tweak the connection and I need a modem that will be stable at an SNR of 5dB and below. I currently use a 2Wire 2700HGV which is pretty stable but it's quite old now and there isn't much to tweak.
So, what routers have you guys used and would recommend for my connection? I am on a 40dB attentuation.
Just wondering what type of connection you wish to tweak ? i.e. adslmax,LLU etc.
ADSL Max :)
Have a look at the Billion 7800N as it has the facility to tweak the SNR.

I have tried the 7800 non N version and didn't hold the connection well at all. :(
But I am starting to think that it might have been a dud as other people are reporting than it can hold the connection at at an SNR of 3dB and below on higher attentuation connections than mine. ???
That router is good on long lines. I wonder whether you have an internal wiring issue, what else is connected to the phone line.
I have a BT fitted filtered faceplate, connected to the extensions are a DECT base station and an old wired telephone.
Try removing the faceplate and plugging the router into the test socket revealed, see if that helps.
It doesn't :(. I have tried that many times before.

That depends on the line quality. What are your stats like?
Stats:
VPI: 0
VCI: 38
Broadband Negotiated Mode: G.DMT Annex A
Connection Status: CONNECTED
Speed (down/up): 7264 Kbps/448 Kbps
Number of Retrains: 0
Number of Retrains Elapsed Time: 0H: 00M: 00S
SNR Margin (Downstream/Upstream): 5.0 dB/25.0 dB
Attenuation (Downstream/Upstream): 40.9 dB/24.0 dB
That's all my unlocked 2700HGV gives me.
Given you've got a 1db noise increase from your last resync at a relatively 'quiet' time of day, I'm not sure you'll be able to maintain a stable connection at 3db. If you can, it will step up your profile, though.
That's why I am looking to find a router to hold the connection at a low SNR like that. It did hold the connection down to 2dB last night. :)
But does anything beat the 2Wire in this situation?
I am trying to find out :)
So far it seems not.
We've members sitting on 3b margins on adsl2+ with basic N Netgears but that's solely down to line quality.
Yep, I understand that. I just wonder if the Billion might deserve another go. What's the Netgear DGN2200 like?
I'm pretty certain Lance is running that on adsl2+with a 3db margin,he should be around later.
I wouldn't bother myself, it would be 2700 or Billion for me. :)
Because I have had one before, but it locked me out of telnet before I could test it >:(
We've also got at least one Draytek Vigor user but can't recall the connection profile.
Does anybody have anything else?

I do and I am :)
The router seems good and when I was on Max performance was about the same as the 2700. However, I've got a stable 40db attenuation adsl2+ line now (currently noise is at 1.4db). I've not tried a 2700 on my line since getting adsl2+.
I am running a Fritz!Box 7390 on an ADSL2+ line. Connection speeds 17240/1059 with a Downstream LA and SNR of 18 and 3, and upstream 6 and 6. Connection has been up for nearly 3 days with a Downstream CRC error rate of 0.49 per minute and Upstream error rate of 0.06. Downstream SNR varies between 2 and 4. Best price for the box at the moment is with Mom 'ILC. I have bought 2 phones from them and their service to the UK is excellent.
Does anybody have any experience with the Netgear DGN2000?
I think Lance has one.
I thought he said he had the 2200?
Here is some more info:
I will be using it on an ADSL Max connection
My attentuation is 40dB
I need a router that's good at holding low SNR (under 5dB) without dropouts for at least three days so the BT IP profile system can increase my speed
Tweakable SNR
Hope that helps :)
Yep it's the 2200 I've got.
The best thing you could do is see which chipsets are used in which router. It might be the 2200 uses the same chipset as the 2000.
The 2200 is a Broadcom 6358 and the 2000 is a Broadcom 6348. I really need a router I can get on Amazon as I have Prime and I get free next day delivery. :)
Anymore suggestions. I really need to find an answer to this.
Still looking...
I have the billion 7800n and I have found it great on my long line(63.5db)sync of 3480 @5.2db snr
Hello guys! I am still trying to find my perfect router!
An impossible task, imo, as other people's experiences won't necessarily match yours. For me the 2700HGV is the best I've used, but I haven't tried everything else out there, so my view is subjective.
My V6 2700 HGV on Adsl2+ interleaved holds a margin of 3 down to -1
