Is there a procedure for changing security methods on a DIR-655 router?  I'm currently running it with WPA2 security, but want to change it to WEP.  My first attempt at this failed.  I couldn't get the computer to access the internet via wireless.  And, yes, I did change the security setup in both the router and the client PC.  In case anyone is wondering why I'd want to do such an thing, is that I have network device that I want to add that only uses WEP security.  Any help would be greatly appreciated.  Thanks.
