Speed Drop - Normal, G.INP or Plusnet

I was lucky enough to get FTTC installed at the end of August last year. I'm on a long line for FTTC (Est 1.2km) but was initially getting 25.5mb/s down, 4.5mb/s up.

This dropped over time but seemed to settle at about 22mb/s down, 4mb/s up. Again I was happy with this.

Recently, say in the last 2 or 3 months, my speed has dropped to between 15-19mb/s down, 3mb/s up.

I've been with Plusnet the whole time, I have a ECI modem and I'm on a Huawei cabinet.

Is it worth me getting a Huawei modem to rule out g.inp issues (and get to see the line stats) or does this sound more like a Plusnet speed issue?

Any advice greatly received.

Colin

If the IP Profile recorded at the PlusNet has also dropped (or reported by BT Wholesale speed test) then sync has dropped and a test with a G.INP compatible device is worth while.

If the IP profile still fits in with the older 25 Mbps type speeds, then suggests throughput issues.

Thanks Andrew,

I've just checked Plusnet 'Member Centre', 'High Speed Broadband' (is this what you mean by IP profile?) and it has:
Estimated line speed:There's no speed estimate currently held on your account. Current line speed: 19.9 Mb

I'm sure when I've checked this previously it was at 25Mb.

So this looks like a g.inp issue and it's worth me speeding £30 on a Huawei fttc modem?

Whether its worth trying is down to you, but if getting the modem from that auction place then if it does not help can always auction it off again, or consider it a spare (lightning likes to kill modems)

This is the essence of the G.INP issue:

I have a ECI modem and I'm on a Huawei cabinet.

So I agree it's best to get a Huawei HG612 v3B and upgrade it to the latest firmware.

I had a similar problem about 3 weeks ago. Had been sync'd at 67Mbps down and 18Mbps up and suddenly, at 7pm one evening, my download dropped to 58Mbps and upload to 12Mbps.

Openreach have had their faults team out, swapped cards in the CAB, checked in the exchange and can find nothing. Interestingly, when the Engineer's tester is plugged in and thereby bypassing Plusnet, the uploads and downloads are nigh on full speed which makes me think it's got to be a Plusnet issue surely??

Thanks for the advice guys.

When I get a Huawei modem, is there anything I'll need to do to get the line profile changed or will it just sync at a higher speed (assuming this is a g.inp) issue?

It should go higher straight away assuming the HG612 has the latest software - V100R001C01B030SP08. (Which is also available in an unlocked version).

Right Huawei modem ordered, I'll let you know if it improves matters

So I now have a Huawei modem (unlocked) running the latest firmware (B030SP08), but my IP Profile on Plusnet remains at 19.9 and my speedtest returns a constant 19Mbs.

When I look at the modem stats it states:

Max: Upstream rate = 4361 Kbps, Downstream rate = 26984 Kbps
Bearer: 0, Upstream rate = 3617 Kbps, Downstream rate = 23895 Kbps

Does this mean I need to do something to get the IP Profile reset?

What telnet command should I run to get more line info?

Thanks

What is your real ip profile BTW ip profile BT Wholesale performance tester it's the second bit following the speed test result enter your phone number and press the button, it should after a short time show the IP profile

Hi Tommy,

Test results were:
Download Speed 19.13
Upload Speed 2.98
Ping Latency 45.50

Further diagnostics:
Download speed achieved during the test was - 19.13 Mbps
For your connection, the acceptable range of speedsis 16.19 Mbps-23.13 Mbps .
Additional Information:
IP Profile for your line is - 23.13 Mbps

Upload speed achieved during the test was - 2.98Mbps
Additional Information:
Upstream Rate IP profile on your line is - 20 Mbps

then for a start the Plusnet profile should be 23.10 at least , you could try dropping the pppoe session on the router ,to see if that updates it, if not then ring their support and ask them to update it, the delay in the plusnet profile updating is unacceptable IMO

But the throughput seems somewhere near the mark for the sync, what are the rest of the stats from the modem ? you may have to obtain them via telnet, or maybe a better option would be to download install one or both of the available tools that will log and display the full stats from the modem from Here , kitz forum

It took over 48h for G.INP to kick in for me after putting on HG612.
The increase in sync went up between 12-8mbps ( depending on how far back in history I compare ). HG612 is worth every penny now

Ok, I'm going to leave it be for a few days. Fingers crossed

The Plusnet "Current line speed" updates 2-3 times a day, so I would expect yours to read 23.1Mbps some time soon. You shouldn't need to do anything.

xdslcmd info --show

((That's assuming you have telnet client enabled in your Internet Options).
Sequence:-

telnet 192.168.1.1
admin
admin
sh
xdslcmd info --show

G.INP shows up as Bearer 1 being there as well as Bearer 0. As has been said, it can take a bit now you have the right modem, though mine was immediate.

Looks like g.inp has kicked in
xdslcmd: ADSL driver and PHY status
Status: Showtime
Retrain Reason: 1
Last initialization procedure status: 0
Max: Upstream rate = 4402 Kbps, Downstream rate = 27844 Kbps
Bearer: 0, Upstream rate = 4491 Kbps, Downstream rate = 27909 Kbps
Bearer: 1, Upstream rate = 0 Kbps, Downstream rate = 0 Kbps

Now I just need Plusnet to change my profile.

It should update automatically by mid-morning. At a guess to 26.9Mbps.

Just asked them to raise it via the web chat support service. They did it, there and then, resetting the profile to 40Mbs.
Latest speedtest results (25.9Mbs down, 3.8Mbs up)
Speedtest

Very happy
