So I have brought this up before, The Same happens on almost every D-Link Router I`ve owned.

DGL-4500
DIR-601
DIR-655 Rev C (current)

I really have no clue why this happens see screenshot. I have QoS on to limit my upload so I can still upload while not killing my connection/causing lag.  When pinging with ANY computer on my network including Android phones wired or wireless.  When Uploading Ping Shows anywhere between 250-1000! To ANY website INCLUDING ping to my Cable Modem 192.168.100.1 Shows HIGH ping times. BUT whenever I do a speedtest, Pingtest.net, or in games my Ping shows its fine and Normal.  How come its fine but Ping test software shows my ping being extremely high when its really not.  Its not the cable modem doesnt happen with any other brand of router, I have also tried 2  different brands of cable modems as well still the same.



Its a very weird issue though, This does NOT happen when using FTP, But it does happen when uploading in the browser like YouTube or something

Could be a PING.net behavior? If in game or using other applications doesn't products this and only this one site, could be this site and how it handles the test...

What happens if you try this method?

Still does it, tried that too. Pingtest.net and speedtest.net and games show the actual real ping.  But when pinging from a computer or android device thats in the network it "Says" its high

How do you have QoS set up and configured? Please post a picture of that section.

Just manually imputed upload and rest is default.

What values are you using? I'm wondering if the values you are using are impacting something...

Here ya go. What if I try and manually add some things under QoS engine rules? I`ve never had to do any of that

[FurryNutz]

What happens if you manually set 1024 and maybe 512?

Same thing, It brings my upload down severely but with the same HIGH ping reading in command prompt and on my android phone, but games and speedtest seem fine.

Could there be an issue between the router and the android? If the android is the only one exhibiting this, possible issue on how that device is interacting with the router...

Nope.. Happens on all 15 devices wired or not. Issue is fixed when using 3 other Non dlink routers I have laying around. 


Issue Happens on:
DIR-655 Rev C
DIR-601 Rev B
DGL-4500


Issue doesnt happen on:
WRT54G V5
Really old Belkin
and a ZyXel.


It doesnt really actually affect my Internet Ping though, even though it says it is, which is very weird.

[FurryNutz]

Is that the only ping server or services tested? Can you try something different? Different location?

Running out of ideas here.

Hi,

by sniffing on the wire, I analyzed what pingtest.net does when performing its measurements. They do not at all "Pings" as they are defined by exchanging ICMP echoes and replies.

Instead they play a funny game by forming TCP sessions to several servers (one after the other) and then perform Ping-Pongs within each TCP stream:



Well, I guess that's something completely different than real pings, and TCP buffer mechanisms like send and receive windows result in much lower time values between TCP segments sent as PING to the server and their PONG replies sent back from the server through the same TCP connection.

So whats expected behavior? Is this symptomatic of the Ping Services, Router or Client HW?

Hi Furry,

So whats expected behavior? Is this symptomatic of the Ping Services, Router or Client HW?

My contribution to this thread was just to disclose that pingtest.net uses a technique other than ICMP based pings, and that you may run the risk to compare apples and oranges, if you compare their results with RTT you measured via real Pings.

Indeed RTT values greater than 150ms (measures via ICMP Ping) are not really good. I'd suggest to find the bottleneck in the path to any destinations by using traceroute command ('tracert' with Windows), look for example here.

This might reveal if or if not the router is the bottleneck.
