Just had BHN upgrade me to Lightning 60....what an interesting experience.
Ordered with request to have modem configured in bridge mode to act same as current cable modem.
Tech arrives 30+ minutes late due to difficulty on prior job, contractor agency did call 10 minutes before end of appointment window to notify me that they would be late.
First indication that this would be an interesting experience...tech demanded that the new modem be plugged directly into the wall outlet for power until the office could "hit" the modem after which it could be plugged into a surge protector. He wouldn't proceed until this was done. I didn't know that BHN was using the power lines to manage their network equipment now

After confirming to me that he had this in bridge mode he asked me what I wanted to call the wireless network - I asked why he was setting this up as I wanted bridged mode and would use my own router.
He then let me know that all was good, could I sign the paperwork now. My download speeds at this point were under 30 and upload had increased to over 5, but my router was showing a non-routable IP address. I knew that he needed to go as he wouldn't be able to fix anything and made comments on the paperwork before signing it.
Called BHN and it took a qualified tech less than 10 minutes to fix everything to how it was supposed to work - he noted that they had setup the account with Home Wireless enabled and had to change that to ensure they wouldn't undo the bridge mode. The tech on the phone was great and when done I had greater than advertised speeds for both up and down.
Painful experience with the installer while the tech on the phone was great to work with and couldn't stop laughing when I asked why the installer insisted the router be plugged directly into the wall for power.
I waited a long time to upgrade to lightning as I didn't want to deal with the headaches that seem to come every time I have an installer come out. If I hadn't seen this forum and the participation here of the BHN rep and others experience being able to get bridge mode running I wouldn't have upgraded. End of day the service delivers what it promised which is always nice but I would have liked a smoother path to get here.
Would BHN consider a self install for customers to upgrade to Lightning for folks who want bridge mode? Ship the modem pre configured and have the end user make a call to support if there is anything needed at the remote side.
