Hi All,
Although I've frequented these forums quite a lot, I'm a newly registered user here, and I'm still learning about the technologies behind Fiber connections, and basic broadband technologies in general.
Long story short anyway, I'm not convinced that my line is all its cracked up to be, and although I get decent speeds, I'm sure I should get more as I'm not that far away from the cabinet or the exchange, and the estate I live on is fairly new too.

I've included a link to my graphs if someone would be kind enough to take a look, especially at the QLN graph as it looks suspicious.
Thanks
John

67 Mbps connection is reasonable enough if you are within 200m (of telephone wire, which will be different to road distance) of the FTTC box

So probably less about the graphs and more seeing if line could be that actual length.

Hi MrSaffron,
thanks for your reply, although I have already tried to determine my line length to the cab, the but the only figure I can come up with (from a BRAS Checker) is 1051m. Im assuming this figure is the total loop length.
Do you have any ideas how i could check my loop length?
Also do the QLN and HLOG graphs look normal then?
Thanks

Your QLN graph does show a somewhat elevated noise floor due to (what I shall call) 'generalised mush' but there are no obvious big spikes from broadcast transmitters.
A 'good' QLN graph will be around -140 dBm/Hz across the majority of tones.

Have you checked here https://www.btwholesale.com/includes/adsl/main.html ?Fibre speeds tend to look about right based on cabinet numbers and the distances from them. Probably need a WLR (BT based) line for that checker though...however adsl speeds tend to be rather conservative with that checker since it covers the entire line from the premises to the exchange.

Can you post Connection stats and pbParams? Cheers
The graphs show a tiny bit of interference but hard to tell as they aren't long enough and enough data hasn't been provided.

Ignoring the router and looking at the real world
1. Identify cabinet number via https://www.btwholesale.com/includes/adsl/main.html
2. Physically locate it and estimate a slightly wobbly walking distance
If that is in the 200m region, then not much more to be done.

Burakkacat,
thank you for the technical insight, its very much apreciated. and in my book, 'Mush' is a technical term =)
I have also uploaded the pbparams and connection stats to dropbox for you to look at.
Im on cab 25. please dont hate on me guys, but i already get a faster connection/bandwidth than the checker states i should get, which is why i have never trusted it. (57.2mbps)
Thanks

Ha lol, MrSaffron, I'm far too lazy to do that =)
I know the cab is number 25 and its at the entrance to my estate, I'm terrible at estimating distances so I wont guess for now....
Thanks

Also,
on a separate note, has anyone determined whether Beattie have removed the webGUI from the HG612 in the latest firmware?
I'm not brave enough to remove and re-ball a chip....
Thanks
