Hello, I have 2 WAP54G ver.2 and I flashed with DD-WRT 2.3SP2 - works perfect. Forget about HyperWAP and other FW, DD-WRT works with no serious problems with WAP54 2.0 as AP. I have only one problem - WDS watchdog restart devices when watching WDS IP. So, probably you can't use WDS Watchdog. Reset button isn't working, or I don't know how to enable it. Revert to Linksys FW from DD-WRT with tftp utility or WEB GUI isn't a problem. Steps: 1. Use Linksys FW 3.04. 2. Reset the device. 3. Download dd-wrt.v23_micro_generic.bin from www.dd-wrt.com - 7/20/2006 works OK. 4. Flash the device with dd-wrt.v23_micro_generic.bin That's it. The IP adress will be .245 or .1. Password - root/admin. If you have problem with password and can't reset the device, use the tftp utility to flash directly with Linksys 3.04 after first ping to the device(.1 or .245) and then flash with Linksys WEB GUI to early DD-WRT version without password encryption. To revert to Linksys FW - in DD-WRT WEB GUI flash with 3.04.trx(rename it to the bin) file or use TFTP utility in this thread. If you have questions or problems - let me know. DD-WRT work on ver 3 too, but I didn't test it. Works on ver 1.0 - 1.1 but with many problems and brick. So better don't try, or if you have success - let me know, I didn't. Use only WIRED connection to flash - not with wireless card.
