Title: The addition of my 655 adds to my ping
Post by: jladelfa on February 19, 2009, 12:09:35 PM

Hello,

I just bought a 655 last night in the hopes that my ping woes would go away.  I had a Linksys 54g before; it worked, and when I'd go to speedtest.net, I get the download and upload speed I should, but my ping is high (140ish).  When I removed the Linksys, It'd be 90(ish).

So I chalked it up to the Linksys, went out and dropped a hundred bucks on the 655, and it does the same thing.

I've tried everything I did with the Linksys.  I tried turning off the firewall, opening up ports, giving preference to Steam.

I've got Road Runner 15 down / 2 up, and I live in Tampa and use the Tampa based server on speedtest.  Actually, it doesn't matter what server I use, the ping sucks.

When I remove the 655 and plug directly into my modem, everything is fine.

Adding a router will always increase ping, it's another device that has to process data between your machine(s) and internet.

Major cause for high ping is either a wrong setting in the modem or just a very lousy ISP.

RR in Florida seems to be bad in general.  High pings and stuff are part of the problem...including bad disconnects and such.

In fact, the one server that you play on, where is it located?  It could be insanely bad routing as well, and that's why you see a huge increase in latency.  Routers involved shouldn't cause your ping to jump up over 50ms at all.

To get a more methodical handle on how much latency is being added, don't use speedtest.  Instead, hook up the router, ping the *routers* default gateway from your PC, (ie: one hop after your router is your ISPs router) then hook up your PC directly and do the same thing.

This should give you a reliable baseline to compare against, and it will also answer the question whether this is a low level or high level problem.  Unfortunately I don't happen to know off the top of my head what a "reasonable" latency to traverse a consumer router would be.  Certainly in the low milliseconds, I can't imagine it being more than 20, but you never know.

Anyways, once this is done you can make changes and compare in a very recreatable manner rather than using speedtest.  This should also (I hope) reveal whether this is something systemic to the router, or whether it is something higher level interfering (such as QOS).

Good luck

Cory

Try pinging New Orleans on speedtest.net I'm just north of tampa in Hernando County and I have 140's ping time for tampa and in the 40's for New Orleans server.

So ISP sucks big time.

I think you guys missed the part where he said , he gets 50 ms less without the router.

Could still be the modem(config) which I presume is from the ISP ?
