The line is not great but for 6 months before i had the Asus i was never banded. Within 2 hours of using the asus i had many disconnects - causing DLM to take effect eventually dropping my line from 28M to 22 m. With a sync of 28Mb (it was actually 27.56) my S/N was around 5.5dB so clearly not banded (or if it was i was clearly not reaching the banding level). At 22M i had a S/N of around 10.5dB. Within 1 week of removing the Asus, interleave has been significantly reduced and banded profile increased from 22M to 25M (im syncing with an average S/N of 8.5dB). Im waiting for DLM to increase the 25M banding as my Erroded Seconds are still very low (around 100/day).
I had an openreach visit to check the line - no issues were found.
Clearly the fault is with the Asus or it is not suitable for longer lines.
NO thats a problem line and 28Mb regardless is its limit. If the SNR was 5.5db at 28Mb then thats the best it could handle, anything such as a burst of noise on the line will alter that speed. (Everyone has burst noise now and again).
Banding being removed from 22Mb to 25Mb also seems strange, DLM would not AFAIK remove one banding level and replace it with another which is so close. That sounds to me more like the 22Mb banding had interleaving applied which has now been reduced/remove and bumped the speed up to 25Mb.
If after FOUR months back on the ECI openreach modem things have not improved drastically then thats a sign of your line just being rubbish. An engineer would find no issues if the line is basically performing as best or near as best it can 28Mb to 25Mb (a 3Mb loss/difference) would not be considered a fault.
Its highly unlikely you will ever get back all the speed, the most you are likely to get is 26-27Mb of that 28Mb back, DLM will be more cautious and also during this time more people have probably taken the service meaning more cross talk.
Most of your issues are the line not the equipment on it. A couple of Mb here and there difference with different equipment is entirely normal.
A FAULT caused by equipment and tinkering which induces banding normally results in massive loses, ask Ixel who went from 70Mbps to around 40Mbps (and no it was not the Asus which originally did that, i think it was a dreytek originally...... he will correct me).
Yeah, DLM is gradually increasing the downstream banding and reducing the INP here since removing the ASUS.
Yep
thats what should happen if its been the modem to blame, any cap should get removed eventually it may take a month or two but after that time at most you should be back to normal. If i were a betting man id guess you are back over 50Mb now or close to it and all within a few days (NOT months)
Small improvements like you have seen Ixel will almost be immediate (typically around 48 hours before it makes a small but positive change).
Im sure you will be back up to the 60-70Mbps range soon Ixel, and your issues of banding due to your tinkering with (i think it was) a Dreytek which the Asus in turn never sorted will be a distant memory..... Did you keep the dreytek after your experimenting and it banding you
i can imagine the swearing LOL
ardsar line i imagine has a fault or is just poor if after being back on the openreach modem for FOUR months it has not cleared the banding so something not right there and can only assume if an engineer found no fault (and more than likely reset the line) its just a rubbish line.
