      Download speed reduced by SKY in peculiar circumstances indeed!

      Hi Everyone

      Haven't posted for a while but now have weird problem.

      Am on MID package and router was reset at 4480kbps about 5 months ago by SKY (following previous ridiculous cap at about 2000kbps).

      I haven't complained to SKY, I have had no contact with Sky for months and yet I know find the router is syncing at 4032kbps!!!

      I know the actual speeds will be a lot slower etc etc etc and the usual speedcheckers reflect 3.2-3.7 Mb so this change won't make any difference.
      However, I'm just curious why the router download speed has changed without any communication/complaint.

      It's bad enuf when you complain and then regret it for months but this is mystifying. It's almost as if they have imposed a unilateral blanket cap for some reason.

      Would be grateful to know if this chimes with anyone elses experiences??

      Many thanks

      Longshanks

      Re: Download speed reduced by SKY in peculiar circumstances indeed!

      you are assuming that sky have done something....

      heres a list of basic checks to carry out

      1 - The router/modem is connected to the Master BT socket, not with an extension cable or in a subsidiary socket. (If an NTe5 socket is present use that)

      2 - The microfilter that the router/modem connects to has been replaced for an alternative to prove microfilter not faulty.

      3 - The Voice service is working correctly and there are no telephony devices on this telephone number that AREN'T voice telephones, e.g. fax, PDQ, SkyBox, Alarm system, CallerID unit, analog modem, Credit Card machine etc...

      And also that all devices on the line are correctly filtered.

      4 - Power cycle the router


      You cant assume nothing has changed, it would be like saying "i used this lightbulb for 3 years now it wont light up but nothings changed.." things break and degrade unfortunately

      if you've not called Sky then they've not done anything...as said, look at things internally...

      Hi

      Your logic is impeccable and you are right.

      1. The Netgear is connected to an extension socket but:

      I have installed ADSL nation faceplate at the Master socket and am using their Pro Plus cable.

      2. The modem is connected to ADSL extension socket which is unfiltered so does not need a Microfilter.

      3. There is no additional telephony or jiggery pokery connected.

      However, I did have to switch the mains off a week ago cos the PC froze and then restarted etc. I knew this risked increasing noise margin depending upon time of day etc etc but didn't realise that it would sync at a different speed.

      4. I will "power cycle" the modem and see wot happens.

      Ta

      Turn it off and turn it back on again.

      Nothing to do with bicycles but I had a vision of longshanks pedaling furiously.

      Re: Download speed reduced by SKY in peculiar circumstances indeed!

      id give it about 5 minutes powered off. There is an old trick to use with DLM on BT lines which may help. The trick is to turn it off once a day for 3 days for about 5 minutes, this tricks DLM into running again.

      There's no obvious mechanism that I'm aware of for that to be true. Do you have a link you could point me to?

      My understanding is that in the BT system (RAMbo) a high level of retraining will trigger Max to believe that the line is "flapping" which will in turn notify DLM causing it to reprofile the line. The consequence of this is that the line rate is reduced and this will generate a sync event which will prompt Max to make a (downward) BRAS change.

      None of this is desirable to the end user in most circumstances hence why BT have the threshold set at 10 retraining events in one hour.

      If turning the modem off then on once, three days running caused DLM activity then those BT customers (including Sky Connect) who routinely turn their router off when not in use would very soon have a very crippled connection.
