I'm currently on BT Infinity 2 but looking at my line stats I see I'm having errors. Does this make my line unsuitable for Infinity 2 or am I better to just keep paying for it?

Line stats image is unreadable.

Looks like 43Mbit down, 14 up.

If so, it is a bit pointless unless you need the extra upload speed. The errors are not worth worrying about, unless the connection is dropping out or you're seeing slow speeds it isn't much of a problem. It looks like your connection has been up for a very long time so the number of errors is even more insignificant when put into context.

BT is in the process of turning on G.INP (impulse noise protection) which may increase speeds slightly/reduce the number of errors - but you may need to update the modem's firmware to the latest one (as you've clearly "unlocked" it)

You'd want to check to see if you are allowed to downgrade though, you may be stuck in a contract (or downgrading might start a new one)

There are actually two links in there, try clicking on the word "linestats" after .jpg in the URL, that gives a more readable image.

Yeah, I found it via his flickr account link, in the end.

Agreed, at 43Mbps download speed it's not worth being on Infinity 2 unless he wants the 50% higher upload speeds... 15Mbps is worthwhile for some people. Also, the line errors reported are of no great significance.

If it was me, I'd downgrade to Infinity 1 if I could do so with no penalty. I would have been thinking about that myself had my steady decline in d/l speeds not halted then recovered recently (they went gradually from 74Mbps to 65Mbps but last week, recovered suddenly to 71.5Mbps.

Might be G.INP - it was turned on my line last week and I went from 70-ish to 76Mbps, as BT are slowly turning everyone on.

Vectoring will be the big one (could push people with better lines up to 100Mbps+) but that seems to have an indeterminate release date.

Thanks for the help everyone. I've had buffering issues with streaming video and thought maybe the errors could be pointing at something. As you've said they're nothing to worry about I think I'll just leave it as it is.

No idea what I did with the image link?? Sorry
Thanks again

Max attainable is 60Mbit'ish so given you are getting 43Mbit something is wrong.

Im expecting a BT Engineer tomorrow. I normally get 55 meg but now its 28 meg. i done several tests through ethernet connection and all reported around 28 meg. I had an online chat with BT last night and the guy said he would have to send an Engineer out. No way im paying £129.99 though from what ive read do openreach not control the master socket isnt that why we pay line rental every month. The problem seems to be coming from the HH4 and the exchange. I have a steady blue light on the HH4.

The 130 quid charge is only raised if the fault is found to be with your kit and not on the network. If it is a network fault then the ISP's pick up the tab. But if it is some dodgy wiring on your side of the master socket or some device plugged into the line causing the fault then you get charged.

Thanks for that Chrisjr, well there doesnt appear to be any problem with my kit the HH4 light is a steady blue so im pretty sure its a network fault. My mum said her friend was charged the £129.99 because once they step over your front door or something along those lines they can charge you. I dont know the details exactly but just wanna make sure.

Just to be clear. You will not be getting a bill from Openreach, they bill the service provider for work they do. It is then up to the service provider to recover the cost of the callout from you, or not as the case may be.

They should not charge you simply for stepping through the front door. They can only charge if the fault is caused by you. See

http://bt.custhelp.com/app/answers/d...on-and-charges

Might be worth following some of the links to the self diagnosis checks near the top of that page, if you haven't already.

BT as it then was (pre Openreach) tried to charge me for a fault that had nothing to do with me or my wiring - but the guy they sent out had no idea how ADSL or networking worked, as long as his test laptop/modem connected and did something it was fine as far as he was concerned.

As with all things BT, the real fault (never getting above 1Mbit/s on a 2Mbit/s line, ever, but the line was connected at 2Mbit/s flawlessly) cleared itself "magically" with no apology or explanation

The maximum attainable is the theoretical for the line, it doesn't mean it is actually achievable.

The maximum "attainable" for my line is 54 Mbit/s, but I know for a fact the maximum I can actually get is 43 Mbit/s because BT offered me a deal of a six month trial with Infinity 2, I get 39 Mbit/s with Injfinity 1, and that is the rate I got. So for me upgrading to Infinity 2 would be a waste of money.

How would I tell if G.INP is turned on? I have a BT HH 3 and the Openreach Huawei modem (firmware-hacked for stats).

I'm not sure if there is a simple way, but I believe one way is to telnet into the modem, type "sh", then "xdslcmd info --show"

You should see values for "G.INP framing" and lookback, and further down values for "INP" under Bearer 0 and 1

I believe the modem statistic utilities that some people have written can also show you

No it will be 90% of it, ill let you do the maths

....like buying a turbo-ised car where the turbo is frequently being repaired under warranty every few months

Except that the maths doesn't take in to account all the other variables between the port on the DSLAM and the BT socket in a house, does it?
