I just tried flashing a couple times with a couple different v23 releases. It succesfully flashes, then gets to the screen where it says "Continue", and then from there I can no longer access the router nor ping it. I had to go thru and do the revival and load the Linksys firmware on there, and got it back up and running. Any ideas as to what may be causing this? My router is a WRT54G V1.1
Don't yet click "continue", just close your browser window. Relax and wait 3-4 min. Now try to access the router in new browser window. Try setting your computer to use static IP.
