Title: 73.7 IP Profile ... 79999/19999 sync
Post by: JordanBlack68 on January 10, 2019, 03:22:27 PM
Hi guys,

ive noticed I've lost a little bit of speed and that my IP Profile is now 73.7 instead of 77.35. Not sure why as I'm still on rtx low. Can anyone explain why and is there anything I can do to get back up to 77.35.

What modem/router do you use?

First thing I would try is powering both off for 15 mins, reconnecting, then recheck the IP Profile.

Hi mate.

I use a HG 612 connected to a Netgear XR500. I’ve tried powering rig off for 15 minutes and still the same

I have the same exactly. I can sync at 80000 but my IP profile is always 73.7 too.

I tried rebooting all sorts, but in the end I gave up. Now I just cap my line at just over 73.7 to reduce FEC errors down to @20,000 per day:
adsl configure --maxDataRate 73730 20100 100000

I wonder if the DSLAM remembers that initially my line had bearer 0/ INPRein=1 till I capped it for a while.
With bearer 0/ INPRein=1 my IP profile was 71.2 ish (even though syncing at 80000 or 79999 depending what mood the DSLAM was in).
Once INPRein=1 was removed I never saw an IP profile higher than 73.7, despite having nice low INP levels (46 or 47, sometimes 49)

Great combo, been running this setup for nearly 2 years.

My IP profile is still correct, retx low

Quote from: Mouselike
The current Downstream BRAS rate is: 43.37 Mbps

on a 44856 sync. 96.687%

I've rebooted a few times recently.

Has anyone who's had this issue tried to get their IP profile reset? Is there such a thing still?
DLM knows the lines are ReTx Low, confirmed by GEA test before and after

My last 2 DSLstats alerts were

Sat 26/01/2019 13:40

The disconnections were the modem being removed then replaced while decorating.

Max your BRAS rate has dropped because your connection speed has dropped, your profile still works out at 96.68%

Outdated GEA test maybe?
Title: Re: 73.7 IP Profile ... 79999/19999 sync
Post by: Alex Atkin UK on March 17, 2019, 08:27:56 PM
Very interesting.  I've never been able to test BRAS before as presumably Zen do not use it due to using LLU?

My new Plusnet line is curious though at:
The current Downstream BRAS rate is: 58.62 Mbps (63.5Mbit sync)
The current Upstream BRAS rate is: 20 Mbps

It certainly explains why I got a good bufferbloat score even without QoS.

That seems rather excessively capped considering my Zen line can do 65Mbit with an around 70Mbit sync. (can't get specifics as its current on an ECI modem)  Clearly the profile doesn't need to be this low but sounds like its pretty normal for BRAS to be rather overly aggressive.

Its curious that my worst performing line actually has a higher handback threshold than the better performing one.  Perhaps because its a brand new line so set to defaults?

(https://csdprojects.co.uk/forums/BroadbandLines.png)

I should have a more interesting picture once I switch to Zyxel VMG3925-B10B for the modems.

It does suggest going with an ISP that uses LLU can squeeze a bit more speed out of your line though.

GEA Test - I was looking at getting my line to Low so capped line but the stats indicated it was on low.

GEA tests show the profile the line was on 13 days ago.
