10 Days into Fibre is this normal?

It has now been 10 days since my fibre was installed, when the engineer tested my line he said I should get speeds near 60mb down and 20mb up due to me being close to the cabinet. Initial tests after he left were 38mb down and 18mb up, over the last 10 days my upload has remained constant at 18mb but my download has got slower I now get between 14mb down and 19.5mb? I have run tests various times of the day and it falls between these speeds both wireless and plugged in, this is only marginally faster than my ADSL2 service used to be is it normal for my upload to be so steady but my download not to be?  Undecided
Cheers

Re: 10 Days into Fibre is this normal?

I've been with PN on fibre for about 3 weeks now. My speed has been a rock solid 36meg down and 9meg up on the 40/10 package. I change up to the 80/20 package at month end!
I check the speed using Speedtest.net connecting to a server in London.

I also use speedtest.net and used the bt checker they advise on the site the results are the same. Wink

That doesn't sound right but if you post your profile from your account or as it shows on http://www.speedtester.bt.com/ i'm sure one of the more technical guys will be along soon and try to help you out.

21.31 Mbps

0 Mbps 0 Mbps
Max Achievable Speed
Download speedachieved during the test was - 21.31 Mbps
For your connection, the acceptable range of speeds is 12 Mbps-0 Mbps.
IP Profile for your line is - 24.2 Mbps
2. Upstream Test: -provides background information.
Upload Speed
5.36 Mbps

0 Mbps 20 Mbps

Additional Information:
Upstream Rate IP profile on your line is - 20 Mbps

We were unable to identify any performance problem with your service at this time.
It is possible that any problem you are currently, or had previously experienced may have been caused by traffic congestion on the Internet or by the server you were accessing responding slowly.

Re: 10 Days into Fibre is this normal?

I would say 21.3Mbps is about for a profile of 24.2Mbps so maybe the profile needs checking and resetting if you should be getting around the 38Mbps, ask one of the PN staff for a reset or put in a ticket for it to be reset, they will probably pick it up in the morning then.

Cheers bud. I guessed staff may have looked at this by now but these forums are obviously not as good as BE unlimiteds were I will raise a ticket. Cry

Re: 10 Days into Fibre is this normal?

24.2Mb is the IP Profile for a connection syncing at 25Mb (96.79%).
25Mb looks typically like a capped sync speed.
DLM caps sync speeds whenever it perceives a "problematic" connection i.e. one that suffers from many errors or one that resyncs many times.
Have you been rebooting the modem regularly or are you aware of many dropped connections?
Assuming you are using a Huawei HG612 modem, you could always unlock it (or obtain a spare one to unlock via ebay etc.) to see and/or graph your connection stats to see what is going on for yourself. e.g:-

Re: 10 Days into Fibre is this normal?

Hi I have had one drop out in the 10 days where I had to re boot the modem and router.

Re: 10 Days into Fibre is this normal?

When my connection suffered from physical cable problems it would resync "on the fly" regularly.
These resyncs were too quick for Plusnet to detect them, so they thought I had a stable connection.
It was only when I unlocked the modem to see its stats that I/we became aware of what the problem was.
DLM really clobbered my connection speeds to as low as 8Mb on some occasions.
The line has now been fixed (after 11 months of faults) & my connection is perfectly stable again.
It turned out to be a poor cable joint between the underground cable & the distribution point (DP) at the top of the pole across the road from my house.
As the fault was intermittent, it quite often showed as O.K. (LTOK) when BT engineers visited (many of them over the months) to test the line.  
My sync speeds aren't fantastic though as I am more or less 1000m from the cabinet.
For you to have such a low IP Profile & sync speeds, it suggests you are either quite a distance from the cabinet, or your connection is unstable or is affected by "noise" interference etc.
As you and apparently the installation engineer have confirmed you are close to the cabinet, it really does suggest physical line problems that could/should be fixed.
You will probably be advised to run the fault troubleshooter & Plusnet will investigate if you do indeed raise a ticket.
