Hi,

Been with plusnet for several years on 40/20 (now 55/10 I guess).

I can hit max. download of 32MBps but notice my line is synced faster - I've just changed to a Zyxel VMG8924-B10A from a previous Huawei HG612 / Netgear combo and it reports:

Plusnet fault ticket GEA report, BT Wholesale speed test & checker results attached.

It would appear that your line is severely impacted. My suggestion would be to use DSLStats to upload data from the modem to MyDSLWebStats so that the people with more experience here can give greater insight. One thing that would be of help is if you could execute the command:

Code: [Select]

xdslcmd info --pbParamsIn the BusyBox shell over telnet. To access the BusyBox shell in Telnet, simply execute 'sh'.

[ejs]

Err, isn't the line rate right in the middle of the clean range?

It's the BT IP Profile that is limiting the speed test result. The IP Profile on FTTC is usually expected to be about 96% of the line rate / Actual Net Data Rate. I'm not sure exactly how long it's supposed to take for the IP Profile to update.

[starfire]

So maybe just wait and see if my profile speed increases?

What's the following link say for your Plus Net speed profile? You'll need to login if not already.

Estimated line speed 50, current 34.2

Your Plusnet speed profile should catch up shortly and you should get around 40Mbps downloads speeds then.

[Ronski]

I think it may be worthwhile if you turn off your modem for at least 35 minutes (hopefully stops it upsetting the DLM), hopefully the correct line speed will register with both BT's systems (the speedtest shows a max of 34.46 Mbps) and Plusnet.

[starfire]

Thanks for all the assistance.

I think I will just leave everything alone for a few days and hopefully the IP Profile will increase, will let you know.

No change as of yet, here is the current status:

I might be wrong but I think that the IP profile is only updated at time of resync, and sometimes the resync can happen to quickly to be csptured

[WWWombat]

As far as I'm aware, the IP Profile (in BT) only gets updated when there is a resync. However, that number might get shuffled on to other places whenever there is a PPP session initiated.

IIRC, Plusnet's copy of the IP profile (visible as "current line speed") is updated sometime after the BT number gets updated ... but that happens several times a day.

If the BT IP Profile isn't correct (in the BTW speed tester), and doesn't change within a day, then I'd be tempted to do the 35-minute shutdown that @Ronski suggested. If that doesn't work, then (I suspect) that @b*cat would suggest leaving the line turned off overnight instead (to relax). If the IP profile (in the BTW speed tester) isn't changing, then you need to report that to Plusnet as a form of stuck IP profile.

This doesn't look like a fault with the line, or anything that an Openreach engineer can affect. It doesn't appear to be worth involving an Openreach appointment.

[starfire]

Well, my IP Profile has increased but not my Plusnet one or my download speeds...

Estimated line speed:
50Mb (This may vary between 35.5Mb and 50.5Mb) - Checked on 2016-08-02 11:30:43
Current line speed:
34.2 Mb

[WWWombat]

Great. Any idea what caused the update?

If the plusnet version hasn't improved within the next 12 hours or so, it'll be worth calling them, or posting on their forum. Mentioning a "stuck profile", and that your current line speed hasn't updated ought to be enough to get them to update it.

[starfire]

No, unsure what caused the update.

I must say this Zyxel VMG8924 doesn't seem the most reliable, it just totally crashed this morning, couldn't ping it at all, all broadband stopped etc. Eventually it rebooted itself and started working again although cannot see anything as to why it crashed - I've just configured syslog on it maybe that will show something if it happens again.

Also confusing what is the most recent FW, their site says AAKL.7 but a support tocket says AAKL.14.


I wasn't sure how long Plusnet current line speed takes to update so will give it a 12hrs + as you say.
