You may benefit from applying some SNRM from dslstats, if you can get on it briefly.

At least +3dB, 6 if it allows.

You appear to have epic amounts of interference :P

Normally the most important graph to look at is your SNR Margin.  That gives us an idea what the line is doing from minute to minute.  The other graphs are a snapshot in time type.  However from what I can see so far:


You hlog looks ok
QLN shows quite a noisy line.  Can you do a Quite Line Test (Dial 17070 and select option 2) to see if you can hear any audible noise on the phone line.
SNR per tone and bitloading, show several tones which has too little SNRm to be able to load tones.  This isnt too unusual with longer lines as it reaches the later frequencies. 
FECs dont really tell us that much as its CRCs and Err Seconds that are the important ones...  but you do seem to be racking up a fair few errors in spike intervals which lead me to believe that your SNRmargin graph will probably be quite spikey...  and you will be getting lots of noise bursts.

OK thanks, I have done QLT many times the only thing I hear is some 50Hz on it.
In the week when nobody needs the internet I will re-flash the modem maybe to an another firmware and try that.

Also I will see if there is anyone at the exchange and ask him  if they did any work there in the last month (when I had my shop a chap called in to get his sandwiches each day on his way to the exchange) as this modem worked well with my line and had a good stable connection for about 4 weeks since I got the modem.

I just can not get DSLstats to work again. :(

Damn, shame!

The long and short of it is, if a HG612 can't keep you online, you have big problems.

It may be wise to abandon your smoothwall setup for a week, get some proper DSLstats logging on the go because with that HLOG, your ISP *may* hit a brick wall with BTOR.

Hopefully not, though. Get on it ASAP.

Best of luck!

The difference is he is on VDSL i'm on ADSL and the modem reacts differently.

After working on the HG612 all day I have not really got anywhere  :(.

I did a re-set with the button on the back and tried setting up for PPPoE, as before I got DSL up but again no way would it connect, I had it plugged into a test machine with the network connection set up to send my isp un & pw, it did nothing only flash the Ethernet port lights on the modem.

After spending a few hours on that I decided to do a re-set again and this time I left the modem lan address as it's 192.168.1.1 changed my Firewall to 192.168.1.4, had to us PPPoA, disabled the firewall, and Nat under >Advanced>NAT.

I did get a few graphs before DSLstats and Telnet packed up. 
Tomorrow  I will re-flash it as there is something wrong with telnet connection even with the modem in it's basic form and that's why DSLstats fails.

Curious, how do you know its 50Hz?  Isnt that noise at that frequency from the mains?  You shouldnt really hear anything much during a QLT.

- Wondering if something electrical is introducing noise on to your DSL, but until we see your SNR Margin graph over a longer period, its hard to tell.  There certainly appears to be a fair amount of noise on your line according to the QLN.

Note the SRN has changed again

As mentioned in my previous post, I suspect from the other info that your SNRm may be jumping up and down.
If it is then its highly likely that you are suffering from RFI/EMI type noise.

Shouldnt really make any difference when it comes to DSLstats which doesnt care about which protocol is used.  adsl uses atm, which is why you need PPPoA, although I thought most of BT's network would also accept PPPoE, but it emulates it as PPPoEoA, so youre best using PPPoA which has less overheads.

A few of us are having trouble on 20c exchanges http://forum.kitz.co.uk/index.php?topic=14627.0 and http://forum.kitz.co.uk/index.php?topic=14594.0

I did see a bt exchange fault changing from msip platform  to msh direct could this be responsible for pppoe failing? http://status.zen.co.uk/broadband/fault-outage-details.aspx?reference=47233

Ah yes..  MSiP closed down so it could well affect 20cn.  Thanks for the linky

Working in Electrical / Electronics all my life 50Hz gets in your bones you just get use to hearing it  ;)
With between 2 to 6 phone sockets in each room with metre's of cable (that's only down stairs as up stairs is not wired out or even got the stairs in yet  :-[ )

The phone cables run in under floor ducts, in separate sections to the mains cable and also service pipes, so they get a bit of induced noise (slight).

ISP said I'm on ADSL because of my long line (By Road:4.7 km)  I'm going to see what else they can do to improve it as I still keep getting drop outs.

I have been trying different firmware but no improvements.
