M7 Pro (MR7400)... Bridge Mode/IP-Passthrough Only Works After Reboot?

As the topic says... If I reboot the router to which the M7 is attached via eth, then I have to reboot the M7 as well before bridge mode works. 

Has anyone else experienced this, or the contrary; bridge mode works without having to reboot the M7?

Also.... what gives with not being able to register the product for support? Netgear product registration either fails and says try again later, or the contact us link through support says support expired on 1900-01-01... Time travel!!!!! Woo hoo! <grumble>... and these compulsory forum tags that don't include relevant products... <sigh>
