The new c1140-k9w7-tar.152-4.JA1.tar update appears to be broken. It fixes the old, old problem of allowing a PPTP VPN to pass through, but now the ssid manager in the security menu doesn't work anymore. It fails to show any ssid that is created, or any ssid for that matter. If you do create one it shows up on the security page itself, but not again on the ssid manager. And you can't do anything to broadcast the ssid, etc. because it never shows up there. This device is running all by it's lonesome, no radius server or anything. Anyone have any ideas?
Update: the command line interface functions properly. I'm not a cisco engineer, and it's not intuitive to use but enough google searches will help you use it to set up the ssid. That still doesn't make up for releasing an interface without completly testing it though. This is an expensive router, we deserve better.
