We sometimes find users who have enabled bridging between wired and wireless networks. Windows users please make sure you NEVER enable bridging for your wired and wireless interfaces. Notice has been posted in the message board and terminal room areas. Seriously offending users such as worm spreaders or possible bridging enabled users are being isolated from wireless network. If you think you've been removed from the network, i.e. can't associate with any of the access points, please contact helpdesk. Optimization of power level is still continuing to reduce flaps between APs. Regards, Woohyong Choi / IETF59 NOC Team
