Constant dropouts unlimited fibre extra

[#1]

8 dropouts in the span of ~2 hours on a Saturday afternoon (experienced 4 of them whilst trying to write this forum post). It's been happening with increasing frequency the last 2 months, starting off with a dropout in the middle of the night then 2...etc. Now the line is unusable in the afternoons and evenings.

Using a bt smarthub 1 (the one with the grey horizontal band in the middle) plugged straight into master socket (the two socket type, one for phone, one for VDSL).

The useless technicolor TG582n died a long time ago, tried to test it recently (when your DNS went down, to make sure it wasn't a fault on my end) and it doesn't even boot up. The white openreach VDSL modem works, but is of no use without a router/firewall and WLAN capabilities (hence the bt smarthub).

my line stats are well within margin so i don't understand what is going on and why is the service so bad all of a sudden, there are no storms or cataclysmic events going on as there were last year.

@0rangecake If your stats are within margin, I suspect  there is a fault in the BT/OR network - you appear to have lost xDSL connection twice on that excerpt from your error log.

[#3]

@0rangecake  Your stats are extremely strange and I would say abnormal. Firstly the error log shows VDSL link up with a Downstream rate of 82971Kbps which is impossible as the maximum sync speeds are 80Mbps down and 20Mbps up as the BT hub says. Also the SNR Margin is 0dB which is ridiculously low and does not agree with the Hub stats. I can't offer any explanation for these wacky numbers but you need to report a fault as the line should not be dropping so frequently.

@RealAleMadrid I hadn't noticed the connection speed/SNR in the log - only glanced at the sequence of events and took the SNR figure from the r/h image, but now you've mentioned it...

@0rangecake 

First thing to check: Is your phoneline clear? Dial 17070 (preferably from a corded phone), select option 2. Once your phone number is confirmed, there should be silence on the line except for the regular 'Quiet Line Test' message - any other noise, report a PHONE problem via: https://www.plus.net/help/report-a-problem/phone/

If the phone test passes, report a broadband problem via: https://www.plus.net/help/report-a-problem/broadband/

Let us know the result - if the tests come back as clear but you still have a problem, we need to investigate further.

The above assumes you still have 'normal' landline connection - if you have a SOGEA (internet only) one, just use the second link to report a network issue.

Kbps vs Mbps?

[#6]

@greygit1 Check the attachment in post #1 - Kbps!

[#7]

@greygit1  Another of your cryptic posts, are you trying to say that 80000 Kbps is not 80 Mbps?  The upstream speed of 20000 Kbps is 20 Mbps. Data communication speeds are expressed with power of 10 multipliers.

I just poked factors of 1024 into a calculator. A couple of 1024 multiplications came in pretty close to the reported downstream. I also didn't assume the same code would be used for upstream and downstream calculations. Perhaps the source code was implemented by different teams. Stuff happens.

1024 is also deprecated in storage computations IIRC. But there may be people who still think binary when it comes to computing.

That's all.
