A:Answer I've had both, and I've had those same disconnect issues with the RAX80. Eventually the Netgear just died and since it had issues even when working I didn't bother trying to replace it. The Alien has better range in general, slightly less performance drop-off as range increases, and never disconnects--it's rock solid. Plus, the Alien is better at meshing (to other Aliens, at least) and includes a free (if slightly proprietary) VPN.
With the Alien, there's also none of that silliness of having to pay a monthly fee for advanced features (although there aren't that many aside from the VPN).
P.S. - anyone want to buy a broken RAX80 that never worked right in the first place?
