I have been an "Infinity 2" user for some years now and have experienced steady (circa) 50Mb/s download speeds since the village was upgraded to fiber and a nice new green box on the corner of the street.
I am happy with 50Mb/s (12Mb/s upload).
Throughout April 2017, as OpenReach have roled out the upgrade, we have experienced outages from 8:30 (bang on) for a couple of hours each day for the odd week here and there. Irriitating but it's all for the greater good. After all this faffing about I tested the speed and got 38Mb/s... consistently, +/- just a few decimal places. This has now become the norm. I was getting 52Mb/s consistently, +/- just a few decimal places, now its climbed from 38Mb/s to 40Mb/s but thats still 12Mb/s less than it was.
No new equipment has been instaled here, the only change in useage is DOWN as my 20 year old son has moved out and I get the same results wired or WiFi as it's in the same room for testing. Ther is no difference if the SmartHub5 is on a long extension (with filter and the norm for the past 8 years) or pluged in at the Master Socket (with filter). So, BT tell me the exchange is fine,no changes, the line is fine so it must be us. Nope. Nothing changed. One day it was 50Mb/s then it was 38Mb/s.
Something HAS changed at BT's end of things and I suspect it is a setting. 40-ish is "Infinity 1", higher to 76Mb/s is "Infinity 2". It seems too coincidental that my new speed is so close to the "Infinity 1" limit for that IS what it is: a limit.
I even tried to get an Engineer to call but BT cancelled the call as they said there was nothing wrong!
Welcome to this user forum. @Seti-Yeti
In order to find out what services and speed range you should be getting, please enter your phone number into this form.
Broadband availability checker
Please remember to edit out your phone number before you post the results.
on the HH5 can you go to hub manager then troubleshooting then helpdesk and post lines 1-12
Could you please post the results from the BT Wholesale speed checker, including the further diagnostics. This must be done using an Ethernet cable.
Here is the availabilty checker data.
I followed the Troubleshooting and ended up with
Please get in touch with us so we can help to resolve your problem."
Wholesale test results:
Download speedachieved during the test was - 41.09 Mbps
Upload speed achieved during the test was - 12.82Mbps
From homehub connection status:=
6 Days, 0 Hours 59 Minutes
7 Days, 15 Hours 43 Minutes
The availability checker is showing that the connection speed should be between 46 and 62Mbs. You are connected at 44Mbs which is quite close to the bottom of that range.
What is the downstream noise margin on the HH5, and does it show a max data rate figure?
Unless you need the extra upload speed, it may be cheaper to downgrade to Infinity 1.
Your line has been banded by DLM due to instability, 44Mbps is a band boundary. If you maintain a stable connection and your line is ok, DLM will eventually relent and restore your speed although that could take several weeks. I suspect it has already moved from the 40M band to the 44M as you were previously getting 38 download and now getting around 41
Hmmmm, so all the on-off-on-off-on caused by the OpenReach roll out may have be detected as instability and I've been "downgraded" to cope? If that is the case it would have been nice to be told by BT instead of the stuck record responses I've been getting. So, I should wait for a week or two more to see if it recovers "naturally"?
I guess I can do that. 40Mb/s isn't bad per se so I shall sit on my hands and wathc the proverbian space...
Thanks one and all - I may be back!
