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

Date: Fri, 28 Aug 2009 10:44:44 -0400
I'm trying to capture traffic from computer 192.168.1.2 to the outside world (ie, 192.168.1.2 connects to Google.com). Currently I don't receive any of the HTTP packets nor TCP packets unless they are sent from computer 192.168.1.1 (where I'm capturing). On another network though, I can see all connections made (ie, 192.168.100.2 connects to Google.com and I can see it on 192.168.100.1).

All computers are transmitting packets by wireless to the router.

Thanks for your quick reply.

I'm not quite clear about what traffic you are trying to watch. Is it traffic between 192.168.1.1 and 192.168.1.2 which is going over a wireless link, or is it traffic between 192.168.1.2 and some other machine, again over the same wireless link, and you are trying to monitor this traffic over the same wireless link, or something else?
 
In any case, I would recommend not watching traffic via a wireless link if at all possible. See http://wiki.wireshark.org/CaptureSetup/Ethernet for information about how to connect to the network with Wireshark.

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.
