My average speeds

[JPag14]

I do have stable speeds and thankfully much more stable than my previous ISP that I switched away from. Not much of a complaint but just curiosity and slight frustration knowing I could get more.

The contract I was given showed a minimum guaranteed speed of 55 with min download of 61 and max of 73.

About a week ago an engineer came to replace the cabling by the cabinet as previously I was capping out at maximum 25.6.

I started getting sync speeds of 66/67 for a few days and shortly after I requested to change to a static IP address as I kept getting bombarded by emails regarding security of accounts etc. due to constant change of IP. 

I am now getting sync speeds of 63.3Mbps with max download speeds of max 58/59 and hasn't changed for 3-4 days. Is this likely the speeds I will be getting from now on? Not once have I reached the maximum 73 and barely maintained above 62 (download speed) except a day from when I got the cabling fixed. 

I've also checked BT broadband checker to see the speeds that my line could get

@JPag14  It's unlikely that you'll ever see the maximum speed, I certainly haven't.  It depends on the distance to the green cabinet in the street and the condition of the wires leading to your property. Also there's a number of tuning settings that select lower speed over transmission errors.

The I.P. address shouldn't be changing constantly, if it is (was) it means the line has been re-connecting.

Now you have a static address the I.P. changes won't occur, but if the line is still reconnecting that would explain the dropping speed as DLM will be trying to stabilise the connection..

Check in the router and see what the DSL stats say, and you will also be able to how for long the line has been up and if there have been any cuts (reconnects).

From what I understood Vodafone uses dynamic IP address and I find that my IP address would be different every morning which is the reason I put a request for a static one.

As for statistics these are mine, I did restart my router this morning as I have had the cable in test socket for a few days.

One sure way to avoid the DLM acting on the line is whenever you gave to disconnect or reboot the router leave it disconnected for around 20 minutes - the DSLAM shouldn't see it as a fault. 

[JPag14]

I did just that twice leaving both attempts for an hour each and weirdly enough both times increased sync speeds by 0.1

[Jayach]

The sync speed is what DLM negotiates dependant on the line conditions "at the time" so yes it will vary a little.

Personally I'm not sure leaving a specific gap between reboots will help, but I don't think anyone actually knows exactly how DLM works.

Apologises to those who do know (or think they do) but I'm just going by personal experience.

@JPag14  I just did the same BT test as you did in your first post. Several lines down on the page should be a max observed speed with the date. What were the max figures?

@Cynric

I'm not quite sure what you mean, here is the whole screenshot of the BT checker

@JPag14 My screenshot has an extra bit. It make take a while to be moderated.
