I just installed DD-WRT .23 on my version 4 today and had it running flawlessly for an hour untill I changed the security to WPA-TPSK. When the router config was saving I got booted from the network (normal), and set up my wireless card with the new password...nothing. I tried to connect with a cable, only to get limited connectivity with the connection being refused. i reset the router only to consistently get the same errors. I tried to ping the router but got the destination host is unreachable error. I even updated my drivers for both adapters but i can't get the router to communicate with my computer. Wirelessly my card can detect the linksys signal but I just can't fully connect. i live in Chicago so there are hundreds of wireless networks that I can log on to so I know that both adapters work just fine. What can I do? And thanks, I'm sure this is a Noob problem but I tried to search for this but nobody seemed to have this exact same problems in the posts. Side Q--Under DD-WRT, what does the SES button do (anything)? i can hold it down to either get no led, orange led, or white led (neither of the three has any different effect).
