    I just updated my Linux WRT56G router with the auto updater from there website.

    I previously had my router configured to only allow secure connections via HTTPS.

    When I attempted to connect it now tells me that the certificate I have containts the same serial number as another certificate issued by the certificate authority.

    Linksys has been no help telling me to simply hard boot the router (which did nothing). Does anyone have for me... does anyone have any idea?

    You should return the router to te factory default setting, which will necessiate you setting up the router again
    These are the instructions from the Linksys Knowledge Base, this is what Linksys meant by doing a hard boot.

    Resetting the device:

    Hold in the Reset button (usually located on the front or back panel) for 30 seconds.
    Unplug the power cord to the device and wait for 1 minute.
    Plug the power cord back into the device.
    This will restore the device's default settings, which includes a default password of admin.
    You can now try to access the Setup page again.

    It still allows you to connect through right, just with that message? If so try a different computer because you probably told it to have 'Linksys' as a trusted domain for issuing security certificates and that means you stored the certificate. The router with the new firmware may use a different public key and/or thumbprint. If it works fine using another computer I would delete the secure certificate on the problamatic computer and it should work fine after that.
