Reboot, and internet connection established, at around 760Kpbs; thought I'd best not reboot again.
Went out came back at 11.15, no DSL or /Net light
Reboot, still no DSL.
eventually achieved internet at:
Downstream 21/4 11.15am
Current Rate (Kbps)
448 160
Max Rate (Kbps)
704 64
SNR Margin (dB)
9 9.5
Line Attenuation (dB)
31.5 55
Occupancy (%)
63 250
Errors (Pkts)
0 0
and DSL keeps falling over, recovers for a time but no interweb.
I'm assuming something wrong at exchange.
Nothing showing recently on Exchange Checker.
Reboot (via s/ware) couplef times, as no DSL showing, then success.
Let's hope current stays, as this is within my usual range:
Upstream
Downstream
Current Rate (Kbps)
448 [color=blue]2656 (Weird)
[/color]
Max Rate (Kbps)
912 2688
SNR Margin (dB)
15 8
Line Attenuation (dB)
31.5 56.5
Occupancy (%)
49 98

SNR Margin (dB) 13 24
Line Attenuation (dB) 31.5 54
Occupancy (%) 53 250

REBOOTING, achieve I/net :

Current Rate (Kbps) 448 2688
Max Rate (Kbps) 904 2720
SNR Margin (dB) 15 8.5
Line Attenuation (dB) 31.5 56.5

Within 10 minutes, speed dropping:
Upstream Downstream
Current Rate (Kbps) 448 1696
Max Rate (Kbps) 908 1664
SNR Margin (dB) 15 12
Line Attenuation (dB) 31.5 56.5

Puzzling/ annoying.

Doing diagnostic check on my TP Modem I see some fails, as below.
Anything obvious I should be doing after yet another reboot.
Can't send small e mails too currently, which I assume is all related.
TP Link Modem:
Test Internet surfing
Test xDSL Synchronization Pass
ATM OAM Segment Ping Pass
ATM OAM end to end Ping Pass
Test PPP Server connection Pass
Test authentication with ISP Pass
Test the assigned IP address Pass
Ping default gateway Fail
Ping primary Domain Name Server Fail
Test DNS Root Fail
Network Connection Status Inspect(NCSI) Fail

Many sites very slow to render, many fail to load at all.
Pinging default gateway shows 2ms, which I assume is OK?
BBC Am I right in thinking this is this bad, especially for UK sites?

on one socket or device.
There'll be a few disconnections whilst this happens, & I know I'll be punished

Fact real speed was just 100
He ascertained fault on my BT phone connection at exchange related to faulty battery connection...and I
Needed to report fault to BT.
Called 151 + their line check came back as No Fault
They said PLUS Net needed to sort!
Eventually BT passed me to Broadband faults, presumably Openreach- their line test showed same result
As PLUS Net had.
They promise an exchange fix by May 1, when I can ask for reset to sort my lack of latency grief.

Saturday with a fix promise of "by May 1", will + Net give me any credit and claim back on BT?

However, you have to use the correct wording to BT. Don't tell them that your calling because your broadband is slow. Doing so will (quite rightly) have them revert you back to your ISP whoever that maybe. You need to ask them to run a line test. A battery contact should be easily found and raised for you by the telecom supplier. Alternatively, bring the phone to us, and we'll do all the testing for you.
