Billion 7800N -early thoughts

So is the noise margin related to interference within the home wiring, and the attenuation the distance to the exchange? I'm using an extension port within the home, but did carry out extensive testing on the test socket months ago which made little difference (and isn't practical for my set up). I have an i-plate too.

These figures aren't anything new to me, always around this but my broadband does seem to be getting slowly, possibly with the introduction of more homes to this the exchange.

Need to determine if the Billion is likely to make a worthwhile difference enough to purchase and try!
 
personally i would get a n55u over a billion.i had a billion for a few days and sent it back a few years ago when they first came out.speed wise it made no difference to my long line(i am in the sticks too) i have recently got the n55u and have seem some improvement in attenuation and snr.speed is mostly about the same as my sky router but with more features and `sometimes`a faster synch but skys dlm kicks in and i am back to 3072 on a 60db line again
 
The n55u (according to reviews) has a different chipset (not broadcom) and doesn't appear to be as good on long lines; contrary to your own experiences of course, which is why I was heading in the direction of the Billion.

Does my line data tell anything about the speed that would suggest improvement with the Billion by adjusting the SNR?

I currently have a rock solid Netgear, but the wifi doesn't work on it and I'm having to use a separate gigabit switch for my network which a new router would replace...but at quite a price!!!
 
Noise Margin SNR------15.5 db---------20 db
I would suggest that this indicates either noise on your line(how are your calls?crackly?)
or maybe `dodgy` wiring in your house
is the ring wire connected?
how long is it from master to router?
are you using a quality faceplate filter? not those adapter box filters :(

Calls are fine, no obvious crackling.

The house wiring is fairly new (7 years) though that doesn't always mean anything!

No idea on the ring wire, I do have phones connected to it. I got the i-plate months ago to sort out the bell ring or something like that, didn't quite understand it all!

The distance from master to router is just up the stairs and across the landing, so depending on the wiring within the walls, probably 10 metres.

The i-plate is a decent one and I have microfilters on all 'used' sockets. I don't have one of them newer plates which does away with microfilters because I was told they do nothing!

If you wish to be totally bored, these are my stats when I carried out tests early in the year, which shows that the line attenuation remains the same throughout which I guess is the distance to the exchange, so I need to concentrate on the best noise margin then? Oddly, look at the last one, the speed increased massively but only for a few days!

Last reading `seems`to me at least pretty good all round .noise margin of 9 is quite good,not great,but
You can always get a router from the rainforest try it and if no better return it under the distance selling act
or get 2 the billion and the n55u
Who is your isp?maybe you can call them and ask to have the snr lowered?

any error stats?

Yes, buying one to try is an option I guess.

My ISP is Zen, so one of the better providers but ultimately still using the same long distance poor lines! I've seen the guides which suggestion that my distance could be good for around 4meg so I assume if my internal lines and master socket were perfect, that would be achievable, but the current noise is reducing this. Is this correct?

Sorry, I wouldn't know where to find the error stats? The connection is stable, always has been, very few drop outs (apart from in thunder storms!), but the speed is getting to the point of being difficult to live with given my usage.
 
If you want to hold off, I can try my DSL-N55U on my mum's connection, I've not tried it on her line since they've added SNR tweaking to the DSL-N55U



On my line, I live 50 metres from the exchange, so I get ~20mb/s on both routers :D
 
Zen is supposed to one of the best isps
What router are you using?
4 meg should be attainable with that attn of 50

At the moment, a Netgear DS834G v5, very old and sadly the wrong version for custom software that allows SNR adjustments. Irrespective of this, I wouldn't do any changes on it because I 100% rely on the connection for my business (from home).

What SNR would I need do you think to achieve around 4meg? Oddly had around 9db at the start of the year yet the connection was no better, so does that possibly suggest that I'm at about the top of what is achievable? I know most neighbours around me get slightly less, but they are with the usual cheap isp's and no adjustments to their router.

For the sake of clarity, I've placed my router back downstairs directly onto the test socket (everything removed, i-plate, phones etc) and will give it a few days to see if the db drops a sufficient amount. If it does, then I'll have to consider the huge expense of cat6 re-wiring. In either case, I might have to try a Billion/Asus.

On my line, I live 50 metres from the exchange, so I get ~20mb/s on both routers :D

Show off :D

I always said I'd prefer outlook of fields rather than buildings and a BT exchange but my view in changing in light of all my mates having 100+meg speeds!!!!
 
Well, I asked Zen to have BT change my db noise margin from current 15.5 to 6 and I've seen an increase in speed from 2.5meg to 4.0meg. I doubt it will stay at this level, but nice whilst I have effectively double the speed. I've been reading up on the Billion SNR adjustment and it seems (unless I'm wrong) that whilst you can drop the SNR manually, BT can easily then re-adjust the margin depending on the stability, so you could just end up with it back where it was!
 
@MDian

I am further from the exchange and get this:

billion.png


Ignore the errors (they were while BT was fixing the voice part of the line)
 
Can you elaborate, are you using a Billion or made any SNR adjustments, or this just basic stats as standard? Mine remains up, but isn't as stable on download, moving up and down and the router is now suggesting a change to 7.5db already, so suspect the noise margin is a major issue for where I live. I had thought the margin was all related to the internal wiring but I'm using the master switch, so am I right to assume that the noise could be between my house and the green BT box at the end of the village?
 
I have adjusted the SNR

Can you explain what you mean by "isn't as stable on download"

Is Phyr on ?

Only ADSL selected ?

Do you have Routerstats?

The noise margin is not related to internal wiring but the entire line (the line card cannot differentiate) though any improvements you can make will help
 
One more thing: since ADSL is banded there is no point in chasing the absolute max rate since it may not give you any more useable bandwidth

e.g. from 3424 kbps to 3968 kbps your IP profile will remain the same
 
Sorry, I don't have an adjustable router yet, which is why I got involved in this thread. My download was going up and down from 400kbps to 100kbps on a solid server download so I guess that is noise/stability related!

My router isn't capable of anything more fancy so are you suggesting that the router has made a big difference to you?
 
The variation you are seeing (if varying minute to minute) is nothing to do with Noise

I have found the Billion to be the best router (for a very long line) by a big margin - and I work from home a lot as well

Where are you in the country?
 
Cheshire, not far from Overclockers, but it is the middle of fields so the connection is poor.

Connection holding at 7.5db at the moment.
