Packet Loss/Poor Gaming.

Hi,
I've been through the faults troubleshooter (Question #79580565) due to my gaming experience being awful. I've also been seeing packet loss. After completing the troubleshooter, I seem to have been switched back to ADSL from ADSL2+, I assume this is part of the faults process. Could one of the DCT guys please either change my line profile as it has stayed at 15.7 despite the BT IP profile currently being at 7.17, I believe this difference can actually make the situation regarding packet loss worse. Or switch it back to ADSL2+, I haven't tried forcing this myself via the router as the troubleshooter requested I leave everything connected.
The packet loss on my TBB graph may seem minor? But in the past I've only seen one or two tiny specks of red. Pathping to various sites (google, plus.net and the addresses of game servers) shows packet loss of anywhere between 3-15% I'm no expert, but I'm under the impression that anything over 0% is bad.
I have previously had an engineer visit due to poor gaming (prior to the exchange being upgraded to 21CN) and he said everything here was fine.
Ps, the disconnections in the first few days of the 10 day training period were due to power cuts, more recent ones were me gateway hopping after particularly bad gaming experiences.
Thanks in advance,
Wo0x.
*edit* One other thing I noticed is the attenuation, I was under the impression that ADSL2+ brings with it a slight increase in attenuation, but I've found it to be the opposite with the downstream. Currently 23.0, it was 19.0 after the upgrade, but after a few days this stayed at 20.0. The upstream attenuation is currently 11.5, but was 13.1 when on ADSL2+ No idea if that is relevant, but I was curious as I'm sure I read attenuation increases on ADSL2+

Re: Packet Loss/Poor Gaming.

Hi Wo0x,
The drop in speed seems to be due to DLM adjustments rather than a move back to ADSL1 although I totally understand how it looks that way.

As the line is stable I'm going to submit an SNR reset, that should go through within a few hours and get the speeds back up to scratch, we'll then have to see how things are for you following that.

The drop in speed isn't the reason I believe it has changed back to ADSL... my router shows modulation as G.Dmt, whereas before I submitted the fault report this was showing as 'ADSL2+'
Hopefully this will change back once the SNR reset completes as I'd rather not change anything myself once this happens, ideally I'd like to stay connected for the full 10 days.
Cheers,
Wo0x.

Re: Packet Loss/Poor Gaming.

Your ping graph does look rubbish though.  Have you done a speed test recently at http://www.speedtest.btwholesale.com/ ?

Yes, I've done several. Just completed one now. That tester has only recently started working for me. Bandwidth and latency results have always been good at speedtest.net, and I get 0% packet loss at pingtest.net. My only reason for thinking I have a problem is the poor gaming, the TBB graph and packet loss on pathping results.
Other things that may or may not be related, sometimes webpages seem to hang until I refresh the page, images might not load and Netflix doesn't stay at the highest resolution despite me having plenty of bandwidth and not using the internet for anything else at the time, though I rarely experience these things, the constant is poor gaming and packet loss via pathping.
Cheers,
Wo0x.

Re: Packet Loss/Poor Gaming.

What did the speed tester say?  What was your profile set to?

Re: Packet Loss/Poor Gaming.

IP profile was set to 7.17.
Bandwidth was 6.89.

Re: Packet Loss/Poor Gaming.

There is definitely something wrong here.  On the 8th your account's sync rate suddenly plummeted from about 17Mbps to exactly 8128.  Suspicious.  This also means your profile on our side isn't right as we haven't seen that come through yet.
Dave is having a dig in BTs systems now.

Re: Packet Loss/Poor Gaming.

That sync rate drop happened immediately after completing the faults troubleshooter. I just lost connection two minutes ago and it has re-synced on G.Dmt again rather than ADSL2+ just as it did on the 8th.

Re: Packet Loss/Poor Gaming.

What router are you using? Looks like the line is sync'd at ADSL1 but other than that no obvious reason why or any obvious problem showing.

Re: Packet Loss/Poor Gaming.

On the bright side, you're seeing a much reduced error rate now. 
I've set your profile to match your new speed so the TM works and we'll have a look next week about why you've ended back up on ADSL1 Sad

Asus N55u... Shall I force ADSL2+ rather than have it set to auto? It had previously always sync'd at ADSL2+ when on auto though.

Ah ok, so I should just leave it for now?

Re: Packet Loss/Poor Gaming.

Apologies if this is considered bumping, but there isn't a modify post option....
I've continued to see dropped packets and had poor gaming, the router re-sync'd on ADSL2+ this morning (Sunday) at 09:03. Downstream SNR is showing as -1.2 Huh Attenuation has also dropped by 3, am I wrong in thinking attenuation generally goes up on ADSL2+?
Of course my BT IP profile and Plusnet line speed are mismatched again. BT = 17.25, Plusnet = 7.15. *edit* Profiles now match, though I did have to manually disconnect/reconnect (01:26 Monday) to see improved speeds.

Re: Packet Loss/Poor Gaming.

Your ping graph still looks awful.  Do you have a different router to try, just to rule it out?

Re: Packet Loss/Poor Gaming.

I can try another router. Someone has picked up the fault ticket

I have tested your connection today and found that some of your connection settings are low. This can cause and issue with packet loss, as such i have amended these settings and you should now see an improvement over the next 24 hours.

This has resulted in a re-sync on ADSL1 again.  Sad
*edit*
I've switched to ADS2+ from auto in my router settings. The fault ticket says
Quote

Customer is advising of packet loss. More than likely due to the 3dB target SNR so will increase to 6dB.
Is this the same as SNR that is displayed in my router? As this is showing as 0.3. Shall I try another router or leave it for now?
BT IP profile = 15.24 Plusnet line speed 17.2.
