Internet Lagging Issues

by May 2, 2012 3:29AM PDT

Basically my friend lags for no reason at all constantly on Xbox Live . He never disconnects but he is always has a conection of 3 bar or less (MW3). This is his info about his set up and equipment:

"motorola gateway modem sbg6580

router- ASUS rt n56u

30 mbps down 5 mbps up

time warner road runner high speed internet

cable internet

coax cable box runs directly to the modem and i got rid of all the splitters on the internet line.

xbox connected directly by ethernet to router"

He also live in Hawaii but his internet was fine until 4 months ago where it randomally started lagging. Any advice on what is wrong and any steps that we can take to fix this problem would be very helpful

I can explain this by thinking over what happened

In the past year Netflix has exploded in use along with a lot of other video over the internet. Your complaint is not at all unusual today and the only fix is to wait for networks to be upgraded to handle the new demands.

The only thing that makes me wonder about your story of the direct connection is those "3 bars" which is usually when we connect with some wireless thing. Tell more.

Also, the cable modem system is well, how to make this easy to understand? It's a shared system where your neighbors can impact your network speed. If 5 neighbors pull up Netflix, your speed drops and you get lag.

Telling More

When I mean 3 bar I am reffering to Online Gaming - Xbox.

In a Lobby in Modern Warfare 3 you are able to see your internet connect in 4 bars with 3 colors. 4 bars = great connection / green. 3 = yellow/orange and 2 or less = red. He is not running wireless at all.

So you are alos saying that his neighbors are affecting his connection?

Today, yes we see that.

Try it at various times of the day (and read the other reply.)

It's amazing to see these delays kick in about 5PM to 12PM around here.

On cable.

There could be any number of issues. It could also be the router, my suggestion is to temporarily exclude the other devices and plug straight into the modem, reboot the modem then, and wait for it to lock back in test again. If its good then you know the issue lies after the cable companies responsibility and you can start diagnosing your own LAN.

In addition to this you can get some pretty useful information from going to 192.168.100.1 on a computer that is using the modem for internet, this includes via the router.

One set of data is the signal levels, for both upstream and downstream.

The other info is the error log, particularly looking for t3 and t4 errors and how many and often they occur.

In addition to that taking a couple pairs of pliers and making the fittings are all tight but not to the point you break what they are connected to, will go a long way toward stopping t3 errors due to upstream noise.
