Wireshark-users: [Wireshark-users] HTTP Packets not showing up

Date: Fri, 28 Aug 2009 09:57:05 -0400
I started up Wireshark currently and HTTP packets (and other packets) are received and can be seen from my computer (192.168.1.1), but any other computer, the HTTP packets are not seen by my computer (for example, the HTTP packets transmitted from 192.168.1.2). Is their a way for me to see these packets?

I'm currently running a Wireless Router WRT310N with wide channel set to 9 and standard channel set to 11.
I'm running Wireshark on a Macbook Pro - Version 10.5.8
The computer I'm trying to see the packets from is my other computer - Windows XP Service Pack 3.

On another network, I have been able to see all traffic from other computers, but not this one. Does it have something to do with my settings in Wireshark, Computer, or Wireless perhaps?

Thanks for the help.
