Hey all im new here so go easy on me, Quick question.

For the past few months I have been getting pretty bad lag in any game I play, WoW , Swtor, even just using the net.

In the games like WOW , and TOR my ping is generally around 50-200+ (On a close by server)

Now when I say 200+ it goes well and beyond 200 normally making me disconnect, or just spike for a good 20 seconds , sometimes just giving me a dreadful delay of about 5 seconds constantly. Where my friends are all at 20-30 latency normally. This is an every day thing and seems to only go away at 1 AM in the morning. Current modem is a motorola sbv5120

Here is a screenshot of the current signal at 1 am in the morning
My connection is a 30 mb ISP: optimum online.

I am not very tech savvy, but i do know that something is wrong not quiet sure what. :p Hopefully where you guys come in

Anyway, thanks alot for any advice!

P.S. I will try to take a screenshot tomorrow during peak times of the signal to see if it changes any if this one looks like it has no issues.

Hello!

The first things you could do are:

1. Play with all bandwith consuming programs off (youtube, streams, ...)
2. Ping google to check for your average latency and whether you are loosing packets.
Press windows button +R, then write "cmd" in the box. A black window appears. Write this:
"ping www.google.com -t"
It will start to test your connection and give you your latency every second. If you see a text saying it takes too long, then it could be an issue with your modem (no loss in wired internet, under 1% in wifi).

You can stop the ping with ctrl +C.

I have tried turning off all bandwith consuming programs, litterally everything and still get the problems time now is 4 pm EST , heres a screenshot of what you requested, my connection is wired, Now I do share this connection with 3-4 other computers via router, I am not sure if that is at all relevant or is possible it can slow a 30 mb connection THAT MUCH

Ok!

In the step with the ping, could you please give me the very last lines of the test: it should give you an average latency, minimum latency, maximum latency and the number of lost packets. Let it run quite a long time (dont break it after 100 iterations). The data will be more reliable :)

From what I can see, your connexion is quite stable, which is a good point to start with ;)

The following steps are:

1. Run a speedtest http://speedtest.net/. Select a server near your location and run the test.
Compares the given speed with the one given by your internet company (dont know the word in english sorry :s).
If it is too different, contact them: they may be issues with the line (not only yours, but for the neighborhood too).

2. If the speedtest wasn't conclusive, start a network analysis.
Here is the tool I personaly use:
http://netalyzr.icsi.berkeley.edu/
Start analysis, it can take a few minutes.
Paste the URL here in the forum: NOT THE CONTENT OF THE PAGE, ONLY THE URL. Datas can be lost if you copy/paste the content :)

3. Can you give us your network configuration?
Are you on the network of your University? or a shared connexion? What is the model of your Modem?

4. Could you please run all the tests again when you feel that your connexion is really bad (lags on WoW, SWTOR...)?

5. There are several technical intervention you can do after that like configuring your Quality of Service, or disable the Naggle, but you SHOULDN'T need that.

6. Last advice / remark: like servers, our computer need reboot or their performance decrease.
A computer that is on since 10 hours will definitely be slower than it would be if it just had been started. Before a gaming session, shut down your computer during 30 minutes, then restart and launch the game ;)

I hope it will help you!

As far as the google ping test here were the averages etc
Packets sent 333 Recieved 333 lost = 0%
minimum 96 ms maximum 536 ms average 118 ms


1. Test 1

test 2 http://www.speedtest.net/result/1832066791.png

2. I cant get this to work

3 Cisco lynksis e-3200 it is a home network router I use share with my family. One of the 4 computers is wireless the other 3 are wired (mine is among the wired). The modem is a motorola sbv5120

4. Will do

5. Not sure what any of that is :p

6. Do all computers need to be shut down? or just mine?

Ok thx!

First of all, the value between the latency given by the speedtest and the google ping have to be different, but by a factor 10.... sounds a little too much to me ^^'.
We keep this information in mind for latter if we dont find anything else: you might need to contact your internet supplier.

Do the other computer have lag at the same time? Or any lag at all?
Try to connect one of your computer directly to the modem, if you dont experiment disconnection / heavy lags anymore, then the problem is not your modem.

In a perfect situation, every computer AND the modem have to be shutted down and restart after 30 minutes.
We are not in a perfect world and I don't think your family will be ok to shut everything down just to allow you to play in better conditions ^^'.

What I do when I am back in my familys home is that I shut the modem down when we leave the house to go outside. ;)

Yes the computers ALL lag, its not just mine I have also tried only hooking up my computer to the modem and the same happens. But it seems like there may be a problem with the ISP? and thanks for all the help this far :p

Then the issue should be coming either from the modem or from your ISP.
I don't know how it works in America but in France, modems are given by the ISP too, so in each case, we french have to contact our ISP ^^.

A common problem is the quality and age of the lines you are connected to... We people are not all equal for the internet :D

Try to contact them: at least, they should be able to help you efficiently.
If they don't, then come back and we will try to fix it partly with QoS and Naggle disabling, but those tips have to be avoided as long as we can because if not done right, it can make things worse :(

alright thanks for all your help ill give em a call tommorow
 
When looking at latency. There is thousands of factors using the internet versus intranet.

To narrow it down...

You want to use the tracert command.

Since you already seem to know and understand how to use the ping command. I won't go into details how to open the command line.


The principle is. We want to see if your ISP is lagging out or beyond it.

So when you use the tracert utility. You will be able to see your traffic leaving the LAN, then hitting the WAN. Which you should see something like 1-2ms inside the LAN IP's. Then at most... 10-15ms on the first gateway... (It won't be a 192.x addy..) Past that. When you start seeing the IPv6 addresses. It should not exceed 40ms for each segment. Though, over 70ms can be normal. For congested hops.

The tracert command..

Code:
tracert www.google.com
Then look at the hops and what it does. I suggest using your ISP address. I would use something like www.rr.com.. Instead of google. Yahoo is a classic.

I would think that requests timing out would add a significantly to your total request time. Those look like your DNS's. If your modem isn't talking to them properly and it has to go through its list of DNS's, waiting for each one to time out, I could see that causing requests to go quite slow.

If you were to directly type an IP address into the browser (for example, http://74.125.224.103/ (google)) does it run faster? If it does then the DNS's may be the bottleneck.

(and I'm sorry I keep writing DNS's with an apostrophe s, but it just looks weird to type 'DNSes' or 'dnses')
