High Pings

[SLee]

Hi all,

I seem to have very high pings
Constantly over 600ms

When I first connected at 2Mb my ping was 49ms

My speed is good, mostly over 6Mb but drops to 2Mb sometimes (about 2 hrs a day)

Is this to do with rather low SNR as mine was near 30dB@2Mb and has dropped to 6'ish dB

[James]

Can you post some examples? SNR will be lower on 8Mb - thats normal, as more speed = less SNR. This should not affect ping times at all though.

Hi James,

I've left everything on router set to auto (DNS, IP)
My router does not have a setting for MTU ? (Presume auto but does not show)
My SNR is between 6 & 7 (more lower 6's), been connected at 7150 now for 6 days and no problems
Going to get a new filter ADSL Nation XF-1e as recommended by Tim

My average ping is over 600ms (Actually all my pings are over 600ms except the one)
My lowest ping and only ping under 50ms was the 45ms
I'm not a gamer so not too bother at the moment but would like to get the best settings I can

[James]

Ah. That's a superficial ping off the speedtester - ignore it. Do a proper ping from a command prompt, e.g. "ping adsl24.co.uk"

C:\Users\Admin>ping adsl24.co.uk

Everyone seems to get sub 100ms pings from speedtest
Rather curious why I'm always getting over 600ms pings from there

[Gargoyle]

Umm, by speedtest do you mean http://speedtest.net or something else?

If you mean speedest.net then I wouldn't worry about it, AFAIAC they are very unreliable anyway.

If you pings to places that matter are fine, then just ignore speedtest.net

[James]

Yes, ignore the speedtest "ping/latency" figures. A real ping is done via the command prompt :)

[techmob]

i have noticed my online gaming has got laggy and has poor latency in the last couple of weeks

normally my ping times are around 18ms to jolt currently they are 27ms, is this anything to do with the poor central performance we are seeing?

i do not have interleaving on, my router says fast and on adsl24 control panel it says it is off

[techmob]

anyone else noticed an increase in their ping times?

[reg shaw]

Yes - getting all sorts of odd faults here. Some websites seems to be taking an age to find, but then seconds to resolve ... pings seem a bit odd ... Not good!

Are you mixing up terminology a bit there? Taking ages to find would imply that the DNS servers are being a bit slow, though usually when people talk about resolving they are referring to DNS. I did notice a slightly slow initial response from websites this morning though not enough to make me worry if anything was up.

As for pings I am getting an average of 24ms to bbc.co.uk and 26ms to adsl24.co.uk, which is normal for me (from Scotland).

[gctlincs]

my checks seem ok - but it's the first time i've checked it since being on ADSL24

the added latency on mine is possibly from my own network setup

Been gaming quite a bit past couple of weeks and i've not noticed any problems at all. Midlands btw.

I've had a problem before where pings increased by about 8ms but it went away after a couple of weeks. Most likely something to do with BT.

Probably.

It's doing the same tonight. I'm getting occasions where I'm loading, for example, Google Reader and clicking through articles there and it will initially refuse to load the pages but after a few refreshes they come up.

I don't know why it's doing it, other than to say it's doing my head in a bit.

Take a look at this thread (http://adsl24.co.uk/forum/showthread.php?t=5520) for an explanation, hopefully it should sort itself out soon.

Nice one - thank you my friend :)

finally my pings are normal, funnily enough all centrals are now green
