I deleted all profiles (Pre). When the unit is in settings under WIFI, it sees my neighbors' networks but won't see mine. Mine is working just fine as I have multiple devices connected to it.
The WIFI not working on the 740b negates a big reason for purchasing it...being able to update...
My new 740B will not connect to WIFI. I watched the videos, read the manual, followed the direction ... and still nothing, even with the unit next to the router/modem.
