Ethernet Data Offloading ... how do you get it to work?

Awesome!  My pleasure. 

One thing to keep an eye out for going forward.  Another user has reported that since the MR1100 firmware update, the captive portal he uses at some hotel seems to be reporting/suggesting that the MAC address of the MR1100 keep changing.  As a result, every day or so (not sure how often) he needs to re-sign in to the hotel's captive portal and re-authorize the device to continue to offload through the hotel's Ethernet network.

I'm not sure if this is a hotel/portal specific thing or what.  It seems unliklely that the MAC would actually be changing.  More likely the port is going to sleep or just not passing data and so the portal session is timing out?  No idea, just a guess.

I'm not sure if I'll ever use the offloading feature.  Many of the hotels I go to seem to only have Wifi these days.  It's usually slow and unreliable (2.4GHz only) so I tend to use cellular either from my phone or a dedicated hotspot.

I'd probably be much more likely to use the Ethernet to backup my home network in the event that my FIOS went down.  Though given that it worked through hurricane Sandy (despite the fact that I lost power for 10 days) this need seems rather unlikely as well.

Unfortunately since the Wifi range on the MR1100 is rather short, disabling the onboard wifi and connecting a dedicated wireless accesspoint via Ethernet seems alot more likely.  2.4GHz range seems ok on the long setting, but the 5GHz doesn't even cover half of my modestly sized drywall construction house.  Realistically, I get adequate coverage over a 20ft x 20ft area (two floors).  For good speads (>100Mbit) I need to be within 10 feet or so.
