FTTC Speed Reduction

Been on infinity2 for several months now new to our area and have been enjoying full speed, now noticed regular speed tests with think broadband and speedtest.net showing around 60meg.

Its a10% drop line profile set at 76mb according to bt wholesale line test.

Is this possible due to customer take up causing crosstalk/interference on my line or another reason btw 300m from fttc.

Regards

Cross talk would give you a lower sync rate, and hence a lower IP profile, which you don't have.

Perhaps its time to unlock that modem if it's an HG612, if it isn't you can get one off eBay.

You'll then be able to get the stats and see whats going on, or at least if you post them someone will take a look for you.

well heres the stats from the modem previous was 106 attanable and full sync rate.

Looks like you have FEC & interleaving turned on, presumably caused by the rate of errors that you were incurring. This will eat a chunk of the attainable - usually around 20% - and add a chunk onto the latency - usually 8ms.

Can you get the output from a telnet session, and leave the modem running a while before you take the stats? It'd be useful to see the error rates.

The output from the "--pbParams" option and the "--stats" option would be best.

Yes ping rate seams to have increased.

how do u output a telnet session do I need to install any software.

Managed to get telnet up and running. I want to plot graphs and stuff. downloaded apps can they run standalone from dos window tool supplied connecting to the 192.168.1.1 address

Or do i have it all wrong.

The telnet app is good for getting detailed text out, for reference later and for posting here.

However, the long-term logging/graphing apps are good for making graphs to visualise the changes - either as one-shot snapshots, or regular polling. There are two around, but I don't have the links to either...

One is from Bald_Eagle, which I use, and the other (I think) is DSLStats.

Hopefully someone will give you the links...
