This is an interesting dilemma which I have pretty much neutralized when I use my older, original MPW while at home. When I power up the MPW, I have it configured to always connect to my home network. There are quite a few advantages to using the MPW (in fact, any wireless drive) this way; this problem being one of the reasons. Once MPW is connected to network, it never has the problem of not having another signal to connect to, so its Wi-Fi never turns off as this particular issue describes.
Now, for the other advantages. The Wi-Fi signal of a wireless drive is less robust than a powerful and quality dual-band router signal. The range of any wireless drive can’t fill a whole house with signal like a router can; especially with a few range extenders around to fill in the gaps of signal strength.
The “trick” for great signal is to have the MPW within 10-15 feet of the router. I can be on the other side of the house from the MPW with a tablet viewing a movie from MPW and have a perfect signal and have no weak signal issues.
Wireless devices can access the MPW from anywhere in house, and of course wired devices (like computers and WDTV media players) have no connection issues to MPW via the router.
My wireless devices all connect to the router Wi-Fi on 5G; 2.4G is not ideal for HD video streaming, and I can even be connected to my older 2.4G only MPW at 5G through the router connection. This method improves video quality, although the MPW is connecting to router via 2.4G but my tablet/phone and other devices can connect via 5G. Cool.
So, one might be tempted to keep the MPW plugged into its power supply 24/7 to get max advantage of these benefits, but don’t do it. The batteries don’t like this long term power connection. For a two hour movie, one could plug the MPW in for say, the length of a movie if the MPW is say. 80-90% charged, the battery will not overcharge while running the MPW for a movie. BUT, unplug the power supple shortly after the movie ends; especially if battery is fully charged. One can also use a hefty battery bank to MPW instead of it’s power supply, OR to charge the MPW.
One final important reason to always connect your MPW to your router Wi-Fi: you retain your internet connection for your mobile devices!
I also have a Sandisk Connect wireless flash drive I keep in a pocket when I want my media while on the move, but when at home, even it is connected to the router to get the many advantages of doing so.
