After trying for about an hour to send an email, we got on the horn with the technician who said the modem looked zapped and that a technician would arrive to fix. We waited for forty-five minutes and no one came. At 11:30pm at night, we decided we could not afford to wait for someone to come as we needed to be up and working by 5:30am.
We called the front desk and asked for a different room. Luckily, we were switched to a room on the same floor and our room keys were "magically" assigned to work in the new room without having to go down to the front desk again.
With some trepidation, we signed in from our new room and as of 11:45pm last night, we've had no difficulties. Still, we plugged in the ethernet cable just to be safe. And yes, The Mirage wiped all the internet charges from our bill due to the inconvenience. NOW, we can begin to enjoy Las Vegas worry-free.
