Wireless Network Problems
From MobileRobots Research and Academic Customer Support
The most common problems with wireless setup are incorrect ESSID or network security settings. The ESSID needs to be the same on the robot and the rest of the network. MobileRobots initially sets the ESSID to "Wireless Network" (or "WaveLAN Network" on older robots) during installation, but your network may use a different ESSID. See above for notes on how to change the ESSID. For questions about what security features need to be used, consult your IT department or network administrator.
One possible cause of poor performance is a mismatch between the 802.11 wireless networking modes (a, b, g) of the robot's card and the access point. While theoretically, the modes are downward-compatible, the interaction/negotiation between the client and the access point can interrupt the network or cause poor or intermittent performance. Try changing the mode of the access point to match that of the robot's card, or vice versa.
If the problem does not seem to be in the settings, there may be a problem with the
driver or hardware installation. Run (as root) lsmod, /sbin/iwconfig, and /sbin/ifconfig Contact support and send the
output for each program and a description of your networking problem.
