Ping has just went uo for no reason?


[link to this post]
 
Hi guys,

I usually do a pingtest a few times a week at pingtest.net, and it is always between 45ms and 46ms when I ping Maindenhead or Milton Keynes, now today I do it and it constantly pings at 60ms and 61ms!!!

What is going on, I mean my speed is still the same, so no problems there, but with the ping going up that much for no reason, it now means i'm a much worse connection on Call of Duty multiplayer games?

My interleaving has been on for years, so nothing to do with that. I'm just stumped as to why it has went up by so much for no reason?

Those latency results are not 100% reliable.

Use BQM to create a graph to show you the connection over time.

The thing is that my ping has been 45/46ms to Milton Keynes and Maidenhead since we took out BT Broadband (2 years ago) and now today it has went up to between 60 and 65ms to the same servers for no reason, nothing has been changed, and I need the ping to go back to normal so I can enjoy online games!

Infact my ping has went up by about 20ms to all servers for some reason! I really really hope it comes back down soon.

Just don't know what to do.

As I said, add BQM to the line and then you can monitor it.

Another thing to consider is that BT have been doing upgrades to many exchanges over the last few weeks and ones that had interleaving removed have found it being reverted back to auto.

What exchange is it? The link to what samknows says about it would be great.

Also if you could find and post the stats from your Home Hub. See here for help.

It could be BT have changed the way your service is supplied. That info might give us a clue.

Its a smal exchange:

http://www.samknows.com/broadband/exchange/NSLOS

And my router stats:

Downstream 8,128 Kbps
Upstream 448 Kbps


ADSL Settings
VPI/VCI 0/38
Type PPPoA
Modulation G.992.1 Annex A
Latency type Interleaved
Noise margin (Down/Up) 10.8 dB / 25.0 dB
Line attenuation (Down/Up) 26.7 dB / 14.5 dB
Output power (Down/Up) 14.0 dBm / 1.8 dBm

Bt shouldn't be upgrading the exchange, as it is so small. I just dont know why my ping has went up, my interleaving has always been on, never had it off.

There is a possibility that your IPStream (ADSL Max) service has been moved from IPStream (20CN) to a hybrid 20/21CN system called IPSC. See here for an explanation of that.

How long has the ping been bad?

When was the last time you rebooted your router, or even better turned it off for 5-20 minutes? 23 Feb? Was that when it went bad as well? Daft though it sounds, both can sometimes sort this kind of thing out.

In your case I don't think it particularly likely it will, but certainly worth a try.

Is your IP Profile back to normal yet?

It has been like this for the last few days, so probably about the 23rd or 24th that this started. I have just restarted my router today, to see if it would solve the problem, but it hasn't.

Just strange as hell that for the last 2 years my ping has been pretty consintant and stable at around 45ms mark, and now it has went all the way up to over 60ms.

I'm hoping that it fixes itself, as I think there is very little I can do.

Steve

P.S. I presume my IP profile went back to normal as my speed has increased back to 6.9 ish

[re: Spikester84] [link to this post]
 
I have a feeling it could be you have been moved to IPSC. That is a major change of connection technology between the exchnage and your ISP (BT).

The old technology was one of the best for pings. The new one we have yet to find out.

As uno recommended, it would be a good idea to set up that Broadband Quality Monitor. That way you can see what the pings are doing 24/7 not just when you do a speed test.

Something funny has happened, strange how for 2 years, no problems with ping and now it is awful! I can't see them upgrading my exchange though, it is rather small, and the city that we are right next to hasn't even been upgraded to 21CN yet.

Why have you repeated the same thing three times? Do you think we are blind?

Why haven't you set up a BQM?

I can see the ping has went up, setting up BQM will just show me what I already know surely?

It records it 24/7 as long as your router is on. Doesn't need the computer on. So you can see if it is constant or highly variable.

All it does is tbb ping the router every second and record it. Doesn't use any resources on your computer, and also shows packet loss as well as latency.

Latency type Interleaved


Bt shouldn't be upgrading the exchange, as it is so small. I just dont know why my ping has went up, my interleaving has always been on, never had it off.


Why not? Sometimes they need to do software upgrades.

Same thing happened to mine line. Opted out of interleaving and after the upgrade I found it back on (as DLM thinks it is better for me).

Your stats confirm interleaving is back on:

Latency type Interleaved

So give the ISP a call and request they opt you back out again.

I never had interleaving off in the first place, not sure I want to have it off, as it can create instability on your line.

Internet seems a bit slower as well, even though I seem to be getting the same speed test results, when loading a youtube video it seems to stutter at first, which never happened before.

I don't think I will bother BT with this, as I have spoke to them about Ping in the past, and I got the same answer, which was "your ping will be different depending on which server you ping" and while I know this is correct, it still doesn't explain why my ping is so high to every serverm not just far away ones.

Ring them up, and ask them to switch off interleaving, your line will take it, no problems.

my ping has risen in the last week or so for no apparent reason. usually 15ms to uk servers, its now pinging at 25ms :

Reply from 212.58.244.69: bytes=32 time=25ms TTL=52

first i noticed was playing online games that it did not feel as responsive/instant as before. something isnt right with bt's network and tracert shows +10ms extra at the very first hop.

spikester ask bt to put you on fastpath, you sync at full speed with a shorter line than me, so you will be okay with it!! fastpath will remove 16ms of latency and you will enjoy online games more!

[re: smokeymacpot] [link to this post]
 
Smokey, hae you got any old tracerts that you can compare with current ones? It is possible that a small change in the Internet route could have increased your ping time to some servers. You might also have changed to a different route at the ISP that might be taking a slightly different route out to the net.

The routes on the Internet are always in flux and a 10ms change in ping is not that significant in the scheme of things for the net.

[re: smokeymacpot] [link to this post]
 
Without an old tracert to compare to it is difficult to say anything for certain.

It does appear though that nearly all of the latency is in the first hop. Suggests maybe something has changed in BTs network that could have altered the path. Perhaps it is 21CN has changed something?

I am on Sky LLU and get 30ms to Jolt so your ping looks good (I would be surprised if many could beat the ping you used to get). Only other thing I can think of is if BT have moved you from fastpath to interleaved or increased the depth of interleaving for some reason.

One other thought - have you checked the number of errors clocking up on the router - could be that you are getting increased errors that are causing latency?

[re: ian72] [link to this post]
 
i cant find an old tracert, it definately pinged 10ms on every tracert done all the way to hop 5 or6. now it pings 20ms. my router has been synced solid for a good few months, crc errors are very low, my connection has always been brilliant, i am still on fastpath.

i think something has changed recently at hop 2 21 ms 20 ms 20 ms 217.41.167.58 might be regional (midlands) or national?

i thought id come here and see if anyone else had the same problem, sounded like the op may have? no point phoning my isp they wouldnt understand or know what to do lol

unlucky being on sky adsl.. no fastpath means your ping is double what its capable of and playing games on a 15ping is much more responsive. i read somewhere they will let you adjust "max delays" interleaving depth to 8, maybe ask them for 2 or 4 lol

Doesn't create "instability".

It can stabilise already dodgy lines a tad but you can't use reverse logic. The two aren't related like that.

And given your line stats it wouldn't make a pick of difference, apart from halving your pings.
