Thanks. actually before you start soldering, you could check if tftp is enabled 3 seconds while booting This may give you enough time to open a tftp session to the box and reflash the the linksys without soldering.

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.

[Server-devel] high performance wifi
Hi all Last two weeks I spend on ApacheCon eu (Amsterdam) and worked on the Wifi network for the conference. We served over 480 devices during 5 days on 5 accesspoints. This setup is floss and can be copied/modified. The hardware we used is not required. It could be done on old Pentiun 1 hardware as well. Like we did before in WirelessLeiden.nl (50 square km covered with wifi) The antenna's be made locally. (google for onmi / wafeguide / biquad) the save costs. (or buy they to save time) more info: http://wiki.apache.org/apachecon/WiFi The image does work on flash and should work disk.
