You can de-brick with soldering a tll to serial converter on the board on of the linksys. Then you can have a serial line to bios/dd-wrt. In the bios you can enable tftp to reflash the linksys over network. The are clear recovery howto's on wrt's website. I think you the ap to do bridge-mode. If so the only reason for an ip config on the box would be administration and monitoring. Then I would add an ip address to the ap. Since the schoolserver does dhcpd+nat you don't want to do it in the ap. tcpdump may give you usefull information about what is happening on your network. 2ct Marten > -- http://martenvijn.nl Marten Vijn http://martenvijn.nl/trac/wiki/soas Sugar on a Stick http://bsd.wifisoft.org/nek/ The Network Event Kit http://har2009.org 13th-16th August http://opencommunitycamp.org 26th Jul - 2nd August _______________________________________________ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
