How to find out "if a computer associated with your network is causing poor performance"?

Hi,

I have a problem in my home-network. I'm working with a lot of access points, nearly for every room.

Sometimes it happens that I suddenly cannot open websites on my MBP (WiFi), pings rise up to timeouts. In parallel I have no issues with my iPhone (WiFi) and devices which are connected via LAN.

The issue also happens on MB Air and with OSX Mountain Lion.

How to find out if a computer associated with my network is causing poor performance? Maybe you can suggest a tool which will help me in my problem. Standard MBP-tools didn't help.

Thanks in advance,

Kris

Wireshark is a network monitoring tool. It will capture all traffic on your network. Problem is, you'd need the knowledge to interpret it's output.

Another option would be to sequentially unplug/disconnect device after device at the time you encounter your network problem again. That way you might be able to pinpoint it down to a specific device.

My first thought when I read your post was, it might be too many access points. Or they might be misconfigured (overlapping channels) or too near to each other. Or they might be set to Auto-Channel, which would lead to a fight for channels between them, which might result in poor network performance.
