This is a far cry from my previous Exetel (Optus) ADSL2 which constantly got over 1200kB/s, but I accepted it and thought it was probably backhaul congestion.
In the past week the speed has been even more variable, and over the weekend sank to a sustained <100kB/s, sometimes below 10kB/s. I conducted the usual reboots and isolation tests, raised a ticket with all the findings, repeated the findings when requested to in the ticket, then on Monday morning speed jumped back up to 400kB/s following a modem reboot.
Later that day, Exetel advised:
I responded:Please be advised that our wholesale supplier has investigated the reported issue and advising that the slow speeds are due to congested DSLAM. However there is no ETR on this. Should you require further assistance please reply to this email.
They responded:Thanks for your response. Please advise what speeds are acceptable for a congested DSLAM? The speeds I reported are well below what I see as acceptable.
I responded:Unfortunately when your connection is connected with a DSLAM which has network issues currently, we cannot confirm to you which speed is acceptable or the minimum speed that you might get as the speeds can be vary. Current there is no ETR for this network issue.
When Exetel did not respond the following day, I updated the ticket saying:I am currently receiving speeds well below 100kB/s. I do not believe this is acceptable even for a congested/capped DSLAM.
Is there anything that can be done?
There has been no response. The ticket shows as open in the helpdesk, but as complete in the user facilities.Speeds are varying between 400kB/s and 50kB/s. Are the 50kB/s speeds the result of DSLAM congestion?
I remember reading that Exetel consider anything over 1500kb/s as acceptable for an ADSL or ADSL2 service, but I am getting below 1000kb/s and sometimes below 100kb/s.
Is this really DSLAM congestion or something else?
