Piiiiiiiing.....

[Rossian]

.....today my connection has been slower than a slow thing. Ages waiting for a page to turn up, Skype with the kids was a sh11ty picture and drop outs. So I ran a check using speedtest.net. Early afternoon was 0.3-ish MB down and the ping was 1236ms!! Now "normally" the ping is round about 60-80ms. My question is - what affects the ping speed and is there anything I can intervene with?

Use traceroute (tracert in windows) to see where the delay is occurring.

Very unlikely that you can do anything about it. Although if it is at your ISP you can complain, if it makes you feel better.

My ping was 48

Down .88 Mb/s

Up .31

I have no idea if this is good or bad.

I'm on SBC's 2Wire, on my old phone line. I can watch movies on it, but sometimes I get a bit ticked off with the time things take. Still, I bet when they put those wires in, they never thought people would watch movies down them.

This, LR, is your perennial problem!:}

what affects the ping speed


Probably easier to describe what does not affect ping speed. So many factors. :ok:

and is there anything I can intervene with?


Depends on your ping target(s) .... if it's on-net to your ISP then yes, if it's off-net then you would probably be wasting your time moaning to them, especially as a bottom of the pile DSL customer with no SLA/SLGs.

Try accessing web pages hosted on their network and pinging/tracerouting around their network a bit.... it might be that they are having routing issues today.

ping was 1236ms!!

Even for DSL, that's quite a surprising number !


Not wishing to sound like a call centre agent, but have you powered off your router, waited a few seconds and powered on again ? Sometimes an exchange resync does wonders !

[Rossian]

.....thanks to all who have replied. At 0630 this AM all was back to normal, ping was 81ms and the download speed was 0.97Mbs. As I always shut everything down when I go to bed, perhaps there was an element of mixture's offered solution at work.

SD. I got lost in that tracert site and couldn't work out which bit was going to point at possible pinch points. Oh, and I was offered all sorts of software to buy which were equally meaningless.

That's the problems with this computing lark - with a little knowledge you can work what question to ask. The real barsteward is trying to understand the answers which, almost always, assume a level of knowledge that isn't there. It's like learning a phrase in a foreign language and getting the pronunciation pretty good and being completely floored by the torrent of furrin that comes back to you. Hey ho we live and learn - but slowly.

Amen to that.

Rossian,

Yes, one does forget that it might sometimes be worthwile offering a plain english answer to a question.

Perhaps the mods should introduce a new icon to their little collection of picket flag wavers....

An "IT Newbie Onboard" one ? :ok:

[Saab Dastard]

Rossian,

On the command line, just substitute tracert for ping.

e.g. tracert www.pprune.org

[Loose rivets]

Got this to pprune.

Can anyone give an overview in ten words or less, as to whether it's good or bad.:}

LR - for you, that's excellent. :rolleyes:

Sigh . . . :uhoh:

[green granite]

Much better than mine LR

gg,

For an ADSL user in Europe, yours is not too bad. Don't forget the transatlantic hop.

Here is an as near to perfect example from Europe as you will get (very much NOT from ADSL, obviously ! :cool: )....

See how much the transatlantic hop adds before you start shifting data around the US. The rest depends on how good PPRune's connectivity is as to how much hopping around the US you do, in PPrune's case you've got to get over to the West Coast !


My guess is that LR's trace was done from a US based ADSL service.

[Saab Dastard]

Well rivets is on the right side of the pond for PPRuNe - it's hosted in California.

I typically get about 165ms +/-5 to the PPRuNe server(s) from West London.

I'm 102ms from pprune.org.

Show off. :)

[Bushfiva]

I am what I am :). Plus I felt LR doesn't have enough to complain about :}.

[Loose rivets]

Mmm...dust clouds permitting, I'll be over there in a couple of weeks. I might even have to resort to...gasp...dial up.


Funny thing is, I know the password to a local router. Make yourselves comfortable...

I found a cat. I spent a 100 quid on food and vet's bills, then after 3 months, the owner phones me - she'd seen my ad in the local cat charity shop. I'm told its rare breed.

4 years go by, and I see the cat's name on a local signal. "***** the cat" it said. I put in the rare breed and I was in! I wanted to stun them by putting a hi-def picture of their cat on their computer, but didn't have the know how. Pity, that really appealed to my zany sense of humor.
