I'm aware of some customers that have issues with the 740 wifi, but it shouldn't be as bad as you describe. Typically there is one network that is causing the 740 wifi to become goofy - but not every network. We commonly have multiple wifi networks setup on our 740s and 740bs without issue. If you want we can issue an RMA and replace the wifi module in your unit, to see if that helps. Fee for that would be $39. You could also try performing a factory reset to see if that corrects the issue (From the system menu touch Settings, then Initial, then the "Initial" button). This won't affect any of your aviation data, but you will need to reconnect to your wifi networks and probably wait for a new GPS lock.
Thanks,

Thanks, Walter. I'll mull your offer over--but am not eager to do without the 740 just now, and I think I tried the factory reset a couple of years ago, when I first noticed the problem, without any improvement. It's annoying, but not that big a deal for me.
Does the 740b draw substantially less current than the 740? That would be attractive to me because I run a lot of stuff off the Rotax 914's internal alternator, which maxes out at only 20 Amps. So sometimes I have to conserve electrons at night in winter.
Today the 740 connected automatically to the uAvionix gizmo because I had deleted the two other "Pre" networks that were in the list (my house router and one at the FBO that's out of range from my hangar). With only the Ping network listed, it connected right away.
Also, my iPhone connected (re-connected) automatically to the uAvionix AND it could send and receive text messages at the same time. I suppose that worked becuse the uAvionix network doesn't have an internet connection, so the phone just uses the cell network instead.
I had several "interesting" moments during the flight when the phone wanted to sync a flight plan to the 740. And others when the 740 wanted to sync to the phone. The first time, I accepted--and the flight plan that synced was for a different flight altogether. It replaced the one in the 740 that I was using for that flight--very interesting, indeed! I haven't sorted that one out yet, but it's probably just something simple. I'll work on it later.
