Hi all -
This isn't strictly a ROS question, but I was hoping people here would 
have some thoughts. I'm grabbing video off a webcam on my robot and 
using image transport to stream it to another computer on the same 
wireless network. I'm having a problem where shortly after I start 
subscribing to messages, my network latency skyrockets (like 1000ms+ 
ping times for computers on the same network, and bit rate on the 
robot's wifi connection goes down to 1Mb/s from 54Mb/s). I had fixed 
this problem a while ago by letting the router choose which channel to 
use, but the problem came back and I haven't had any luck fixing it. 
It's not a signal strength issue - iwconfig shows a link quality of 
90/100 or better. Any suggestions as to what might be going on would be 
much appreciated.

(I'm using a WRT54GS with DD-WRT)

Thanks,
-Dan
