High ping

[Smuke]

Im experiencing constant, annoying high ping of around 250 ping, on local servers, UK, Germany etc. i have a wireless router, but it's plugged in via ethernet to my computer, ive tried TCP optimzier's etc.

Any ideas?

Im on AOL (Don't, just don't)

Modem is a Bt Homehub speed touch

This good?

Minimum = 249ms

that doesn't look good to me, your computer cannot communicate quickly with the internet if your router can't/

Why are you using a BT speedtouch when you are on AOL? AOL send out ready to use routers iirc.

[Smuke]

They sent that out too us for free?

Im wondering, can i switch from AOL to BT, without getting their call package?

hey man can you post a traceroute to this host?

tracert google.co.uk.

did you configure anything specific on your router? it seems as if it doesnt respond to ICMP(ping) to the LAN.

Is your Wireless router being shared by anyone else? (even possibly unknown to you?)

200-300ms within the country simply ain't good at all.

As solid84 says, A traceroute would be better... it'll let us know if the trouble is "local", "first hop in", at the destination, or somewhere in between.

You might want to disable the "wireless" interface, just in case you happen to have someone "sharing" your connection without your knowledge.

Roger, But I dont want too disable wireless, cos of my laptop and PS3 .

I havent been on PR since, I did this TCP Optimizing thing, so hope this is a better result..

Your problem is local.

67 to 99 ms just to get to the router sitting next to you in your house.

1) Check for a bad cable. Replace cable.

2) Check for bad port. Change to different LAN port on your router (if it has one).

3) Check using another system in your place (laptop), etc.. using same cable and/or port. Eliminate whichever one "the problem follows"

4) Shot in the dark: Check full/half duplex settings (networking->right click->properties->ethernet card->advanced), perhaps they are mismatched.

5) Reboot the router.

6) Go DIRECT to the Internet - i.e. plug your system directly into the feed from BT/AOL/xDSL/CM/what-have-you.

That should be enough things to try... Troubleshooting 101 here; and you're generally better STARTING at "Layer 1" (physical layer) rather than worrying about TCP optimizers etc. at this point =)

You said you also have a laptop connected (via the wireless), what do you see from a traceroute from it?

BTW here's a sample "good" traceroute, and some ms time responses you *should* be seeing:

did you apply the tcp-optimization before or after the problem? heavy mtu-fragmentation may cause higher latency.
