Change in speeds


[link to this post]
 
Anyone else noticed this?

Since our service was installed the maximum we received was about 27Mbit down and about 8.5Mbit up. Over the months this gradually edged down to about 23Mbit and the same 8.5Mbit.

Recently (not sure when exactly) our service has changed. We are now pushing close to 30Mbit download at the expense of upload which now seems be fixed to somewhere around 6Mbit. Our IP Profile is still 10000k up though but the modem suggests 6138kbit is the most attainable for our line.

Firmware versions are the same on the modem and hub as before. Essentially we've gained 5-6Mbit download at the expense of about 2Mbit upload speed.

Might this be a new profile for the service as a whole using different frequencies? I'm not too worried at losing a bit of upload for better download.

I don't think upload should decrease, but it is rumoured that 17a is creeping in. That could add to download.

Similar experience here.

Went from 34/8 consistently to around 39/5 but in last few days that seems to have gone to 39/8

So hopefully the 40 Mbps cap may be lifted at some point, perhaps they're (reasonably) going to get all the firmware upgrades out of the way, possibly adding backhaul and check things are stable before opening the floodgates

No idea if the sync is capped at 40 or if they've now allowed that to float and are just capping in IP

Been talking with asbokid (who did the unlocked firmware) and he thinks the 17a profile has been enabled.

The faster profile for higher VDSL speeds. BT are enabling up to 80Mbit soon I believe.

The xdslcmd diagnostic tool in the Huawei firmware has an info option that will confirm that you are now on 17a Profile....

Ah yes, the OpenReach engineer who came to look at my speed issues last month mentioned that this was on the horizon, he thought it'd happen in the new year.

Probably why they're "setting it up" now so that when the service is offered people can use it straight away
