Billion 7800N -early thoughts

Mine shows connection uptime under status

dmsims,

Are you using this firmware ?

I have exactly the same attenuation

Sync is 3296, SNR 7.9 and errors are much lower than yours

I think you have a wiring issue - they should be better
Hmm, I'm plugged straight into a adslnation faceplate... wiring issue outside perhaps?

We've had BT out in the past; the engineers come in, pulled there faceplate off, plugged in a speedtouch modem, told us there's nothing wrong with the line and that our 'connection is bad because we live in the country and a long way from the exchange.'

A while back, before I acquired a 2700hgv, I did a bit of research... I quizzed all my neighbours on what they were getting!

The results:

No1 – receive 4.32 MB
No2 – receive 0.49 MB
No.3 - receive between 1.7 and 2 MB
No.4 – receive around 1.91 MB
No.5 – receive 2.41 MB
No.6 – receive 3.41 MB
No.7 – receive 3 MB - that was me, with the 2700hgv :(
No.8 – Don’t subscribe
No.9 – receive 3.75 MB
No.10 – No comment
No.11 – receive 0.94 MB


I live in a small, circular cul-de-sac.

Is it worth getting BT out again?
 
The Openreach faceplate is superior

Do you have a junction box internally ? (after the cable enters the house and before the faceplate)

That's a massive variation in speeds!!

If you do call BT never ever mention broadband (say you can hear crackling on the voice line). If they don't find a fault they will charge


(I just plugged my 2700 back in and got a 500K lower sync)

Really? I was told that the adslnation ones were best :(

The line comes into the kitchen from the street, underground cabling... that's where I have the faceplate.

Tell me about it! Something's up here, surely?

I know the tricks :D

Cheers mate!
 
Well after a little fiddling around over the last few weeks, I've managed to get my router more or less 100% over the 3meg line, and usually over the 3MB profile.

As my pings were always really good, I've decided to get Interleaving enabled, as theoretically it might allow me to push that little further, and even with it on, I'm still pushing sub 30ms ping to www.google.co.uk which is fine (I wouldn't have been too happy if it'd been 50+ haha.

Now that interleaving has been activated, what do you think, reckon I can push myself down a few dB on the SNR or reckon I'm already pushing a little too much as it is?

SNR is about 8.5-9 as I've just taken this (at 10:30pm), and as we all probably know, SNR tends to be at its worse late evening to early morning!!

Got one of these routers the other day after my Linksys WAG320N started playing up and was getting the same sort of internet speeds as the Linksys but have just been playing with the SNR settings and have gone from just under 10 mbps to just under 12 mbps "sweet"
 
I'm just about to get rid of my 7800N - the 7800N's sweet spot imho, is flexiblity on connection and stability - hardly ever went down in the time I had it. The downside for me was it's inability to sucesfully manage my familes very busy requirements on an 8mb connection tied in with my gaming requirements. Although it says it has QOS - it never worked acceptably for me to have a family member hitting the internet and have me game. So i've moved to a Netgear 3700 with modem and put Gargoyle firmware on it. Absolutely staggeringly rich firmware, from easy schedules of machines connectivity (down to web pages allowed at certain times), to a wealth of stats, a web proxy allows you to monitor your familes web access and searches, QOS I believe is the only one where it aims to keep the ping at a certain level by reducing the bandwidth till it achieves it. Just a whole load more things too numerous, either way it depends what you are looking for but for a Family network Gargoyle on a reasonable router must be right up there.
 
How are people finding the Billion now? I have the Billion and it's great but I am having some issues with stability, can anybody tell me how to make the router more stable, particularly at lower SNR margins?

Thanks.
 
Guys

Just put my 7800n in, below is the DG834GT stats and below the Billion, whats your thoughts? Purchased the router for gig ports and wifi signal more than anything.... But my download speeds have standed exactly the same? Is that normal..?

7800n stats

I can only get ADSL max in the village and I think I'm 600yrds from the exchange...
 
If you are on adsl max then you are already maxed out speedwise, when ADSL2+ or llu shows up though you will benefit.

God knows when that will be theres only 600 people in the village and I know of no plans to have ADSL+ or LLU :(

Might space to the parish council and see what they have to say about it

I thought the max symnc for Adsl max was 8128kbps?

IIRC it's something along the lines of 7616 with Interleaved, 8128 without. I always forget which way round it goes, but its something along those lines.

You could manually force your SNR lower and see if it did go up at all, but you've plenty of headroom, and 14dB isn't a target SNR (15 is). If you do ever see LLU etc, thats why I suspect you'll do well, as you're running maxed out ADSL1, with reasonable SNR to spare.


Besides, the thing you want to look at is the exchange, is your exchange part of your village? Check out your local exchange on Samknows and see what they say.
I've just had Sky LLU appear out the bend on my exchange, I'd have been willing to give them a try if you didn't have to get Sky's telephone package nowadays :(
 
Can someone help i bought 7800N few weeks ago i decided to have play with tweaking i now have these stats (Adsl Max)

A2pB025f.d22k
DMT Status No Defect
Operational Mode G.DMT
Upstream 448
Downstream 5760
SNR Margin(Upstream) 23.0
SNR Margin(Downstream) 5.3
Line Attenuation(Upstream) 20.0
Line Attenuation(Downstream) 43.0

I read elsewhere to untick settings in Operational Mode section all i have ticked now is G.DMT and i have PHYR on as i beleive my line got noise issues.

Now my speedtouch 585 before buying this router show 39 for Line Attenuation i dont understand why Billion showing higher figures.

I was noticing lag on Xbox with these settings but i think i got interleaving on can you tell without contacting ISP?
 
I found that my downstream line attenuation was 42dB on G.DMT on the 1.06 range of firmwares (currently using 1.06e) but on the 1.05 it was 34dB. This lower value ties in with a Netgear DG834GT and a 3COM i have which also show either 33dB or 34dB. I think its just miscalcing the attenuation and it doesnt affect your sync.
As of today i am now on TalkTalk LLU with XILO (reseller) and my downstream attenuation is showing as 37dB so has dropped 5dB from the G.DMT value! On ADSL2+ it supposed to go up 3-4dB which infact it does compared to the Netgear and 3COM stats.
So to summarise i think the G.DMT downstream line attenuation in the latest firmwares is borked for some of us at least!

I am using Routerstats Lite to plot my noise margin over time, well worth a look and might help if you have noise issues.

I am also using Telnet to pull up more detailed router stats and its within that you can find out your interleaving depth or if you are on fastpath.
On Windows 7 you might have to enable/install Telnet, see here:- http://technet.microsoft.com/en-us/library/cc771275(WS.10).aspx#bkmk_installVista

Create a shortcut with the target telnet://192.168.1.254/

And once logged in to the router (your normal login and password for it) type or paste in adsl info --stats to bring up the router stats.

The "D" line nearish to the top will tell you your Interleaving depth, if its 1 then Interleaving is off and you are using Fastpath.
