Hey guys, little help or advice would be appreciated.
I got Infinity installed in February of this year and since then the IP profile has been lowered a good four times at a rate of about 10mbps per time. I've gone from solid 75-80mbps on the day of installation to the current 38mbps, each time being told that "this is the maximum your line can support".
I found it strange that they had to continuously change the IP profile and why they couldn't just know what my line could support. I've not had many disconnects at all, only one actual issue with the connection which was an area-wide thing I believe, so I'm not sure why it keeps happening.
Any help or advice?
The reason your speed has dropped is because of a noise issue this has caused the DLM to reduce your IP profile to stabilise the line all you need to do is leave the connection alone for up to 2 weeks and once the DLM see the line as stable again it should start to rise again
What john46 has forgotten to add to his copy and paste script, (yep same answer there buddy as seen in a lot of replies, you should be working in India ), is that it can also and most probably take a few months to even see a change, and that's is the DLM has not managed to get stuck, and regarding noise on the FTTC line, it will not get fixed if its within a certain threshold, and that varies between each of the so called BT Broadband experts.
Have fun, and watch another thread ignored and swept under the carpet of bad DLM software/hardware.
But John46 also gave me the same information when my profile was lowered due to noise on my line and the DLM did increase the profile back to it's original exacactly after 2 weeks so it does work if the line noise is short term, but if you are getting consistent noise on the line the DLM will not increase the profile until the cause of the noise is corrected and thats when your stats from the BT VDSL modem (if unlocked) can help you and even Openreach understand whats going on with the line.
No offence John but I know exactly how the guy feels BT should really think about getting this DLM issue fixed because I have the same with my connection all the time it can be running at a nice steady 27500kbps downstream and a good 14ms ping, 0 jitter and then I get one little power cut over night and bam straight back down to 22000kbps, witrh a ping of 32ms, to be honest it gets write on my nerves and then your told you have to wait another 3 weeks for it to increase again and then what happens if you get another power cut 3 days after your line has normalised again?. Back down again, that is what happens, to be honest its really anoying this DLM business, it should get sorted!. 😞 I carnt help it because I get alot of mini power cuts around my area so there is nothing I can do apart from spend £140 on a back up adapter that will stop the issue. I need a battery back up power adapter pack supply but at this moment I am not willing to pay alot of money for something that is not my fault, BT should sort the issue out!!!. And please John bud, if I see that statement one more time about DLM I am going to top myself!. 😞
OK then I blame Openreach, they should sort it out!. Thanks I have said my peice now. They should bring out a new DLM adapter that you can connect to your equipment or phone socket to stop it from happening again.
There is one little problem with the DLM theory that seems to be overlooked though,and that is that profiles seem to get lowered for no apparent reason.
For example,no noise or crosstalk on the line,good fibre link from the exchange to the cabinet,and no power interuptions,but the line profile and interleaving still gets changed.?
I still think that it can and is controlled by OR or BT for reasons that only they know about.
