Had the PN US free speed upgrade applied yesterday morning at 07:30 hrs. to my line, to date, can't get my BRAS IP profile by the normal methods, BT WS Performance Tester (further diagnostics) or the "mouselike.org" facility.
Obviously had a re-synch on the line for the package change and perhaps a DLM reset to what level I don't know, my retx profile has definately been changed from high to low, as well as the normally accepted indicators of this my DS synch dropped by over 3 Mbps but DS data throughput only dropped marginally indicative of the TP ratio having increased.
The BT WS Performance Tester, further diagnostics has always been a bit temperamental and time limited as indeed has the "mouselike.org" checker, however, neither will complete at present regardless of number of try's or time left between attempts.
Could I have had a full DLM/DSLAM reset and be on a "new line" profile ? (with G.Inp being still active)
If this was the case would that prevent the display of BRAS IP profiles ?
-
It's already reported to BT Wholesale as PN aware of this Bras IP Profile fetching isn't working.

Ahh,
Had not noticed this on the PN forum, just assumed that it might be connected to my recent US speed upgrade as was definately working for me before that, all be it with a few attempts as mentioned in the PN posts.
Many thanks for the information.
-
No problem
-
The BT WS Performance Tester (further diagnostics) or the "mouselike.org" facilities are still not working, can't get access to BRAS profiles, as "adslmax" has advised, there is quite a long thread regarding this issue on the PN forum, a staff member has advised he will report to "their suppliers", no feedback to date.
Some PN forum members are reporting that the BT WS checker will work sometimes after multiple attempts, various browsers have been tried by all accepting that there are known speed reporting anomalies with Firefox.
Is this anomaly possibly peculiar to one ISP or is BT the common factor ?
Any other forum members with different ISP's had the same issues ?
-
You need to post this in plusnet forum not here because plusnet staff don't bother come here much now. I am not sure if other isp have the same problem as plusnet for BTW speedtest to fetch bras ip profile isn't working properly.
-
Appreciate your comments, the idea was to get an input from other forum members who are not PN ISP users, much less likely to get this on the PN forum, PN staff member has already given his input a few days ago on the PN forum so really not much point in posting further there.
Don't you think it makes sense to obtain a more reflective cross section of opinions beyond PN ISP users to help to answer the question you have posed yourself "I am not sure if other isp have the same problem" ?
-
Because my other member of the family is with bt and they never had any problem with BTW speedtest with ip profile. I think the only issues between plusnet and bt wholesale on the plusnet system.

Incorrect. Hasn't worked for my BT line for a couple days either.

Thanks j0hn,
Did think it strange that only PN was effected.
There are still a few members on the PN forum thread reporting that it is still working for them (eventually), it's just annoying for me at present with just having been PN US speed upgraded, the reset/re-synch having produced changes on the DS side also, would like to see what my BRAS IP profiles actually are now.
-
All I'm getting with the further diagnostics test is best efforts Downstream & Upstream with EE it is not showing the IP Profile like it used to.
example old IP profile
-
I just wish PN should add on the member account PN IP Profile & BTW IP Profile on it, so we don't have to kept running BTw speedtest is rather annoying.
Why don't BTw put on DSL Checker instead with a real live BRas IP Profile if enter telephone number! In this way it would be better.

Yes,that's the problem, the "further diagnostics" fails to complete so no BRAS profiles displayed, it's the same using "mouselike.org", the information from BT is not available, with 3 different ISP's to date getting the same results it seems obvious that the common factor in this case is BT.
-
Just tried it on my AAISP line and it worked first time!
-
worked an hour or 2 ago (BT business) for me as well.
-
Sound like only three branded names Plusnet, EE and BT are BT Group with BTw speedtester problem. Never had any problem with my past ISP such as Entanet, ADSL24, Free2Surf, ADSL4Less etc. Only Plusnet have many problem. Might consider switch to AAISP soon.

This is the ISP i am consider move to.
:clap: :clap:
-
The plot thickens, strange !
The "further diagnostics" bit of the BT WS Performance Checker has always been a bit temperamental with me, rarely worked on the first attempt, same goes for the "mouselike.org" BRAS checker, as they are both accessing the same BT system to obtain the BRAS IP profile perhaps to be expected.
Neither have completely refused to work at all as per the experiences of the last few days.
-
my zen based connection that uses BTW isn't able to retrieve the BT IP profile either, it's random who is able to get it, also it doesn't do reliable speed test either reports 25mbps ,lol

There was a large hosting server outage in Europe this week from Tuesday to Wednesday the location Germany but France was also down.

Not sure if you are aware, there has been a known issue with BT WS Performance Tester speed reporting for some time depending on which browser you are using, I first noticed this on Firefox, even the latest Quartum version is still the same, I now use Pale Moon when speed testing via BT WS site, this consistantly produces correct results.
See other forum threads on this issue.

Tiffy what you can do is use your current sync rate for example say 39999kbps if your on RTX-Low/fastpath you take 96.7% of current sync rate 39999kbps which = 38679kbps your IP Profile (38)
If your on RTX-High you take 92.0% of current sync rate 39999kbps which = 36799kbps your IP Profile (37)
So your DS IP Profile would be 96.7 percent of 36906 = 35688kbps IP profile (36)
-
Maybe Kitz will make this one so we can it work out depends on interleaved on DS
-
@ NewtronStar
My DS sync rate 73998k with interleaved (8) (52.00) mean Bras IP Profile would be 68078k - is this correct?
-
It works out at 68078Kbps so that is 92% high RTX re-transmission IP profile (69)
-
TBH Max you would be better of on fastpast or RTX-Low 96.7 if your line can handle it and this XdB is just a gimmick it does give you more sync but the RTX-High 92% overhead takes most of what you gained away :(
-
I have to find fastpath modem (without G.INP) any idea which modem?
-
It's nothing to do with G.INP it's this XdB once that is removed off your line RTX-Low should be enabled again.
I suppose you could use a HG612 with old firmware IE non compatible with G.INP :-\
-
Sorry for being dumb, where can i find XdB on DSLstats?
-
Xdb is not on DSLStats it is applied by DLM and is another name for lowering the target margin to 3db.
-
Can I ask PN to reduced target SNR 3?
-
No, the ISPs can't control the SNR target on FTTC lines
-
Here is screenshot (top one is without DLM :) and bottom one is with DLM :no:

-
adslmax's issue (http://forum.kitz.co.uk/index.php/topic,20549.0.html) has nothing to do with XdB. The DLM must have seen something bad happening, apparently a Hub One rebooting a few times, and so decided to increase the level of retransmission and then band the speed to 74Mb. The DLM never tried to lower the target SNRM, adslmax was already connecting at the maximum possible speed.

Back on the original topic.
Yes, I appreciate I can "reverse engineer" my known parameters and work out what my BRAS IP profile "should" be, I know that I am on retx low profile since the last re-synch, however, if you can remember back to a few weeks ago when yourself and j0hn advised me that my IP profile was stuck and I should drop PPP session to reset, I chose to disregard this advice for some time but eventually applied resulting in a substantial DS synch/data throughput increase with the new DS IP profile.
It's nice to know what the BRAS IP profiles actually are as well as what they "should" be by data TP ratio calculation based on retx low/high profiles.
