I have also the same problem that I had with the chineese 8188FTV,  as
soon I connect it to the raspberry pi it reboots inmediately. In the
next reboot it works fine. It occurs the same in another Zero W that I
own  with Raspbian and a different power supply. So I doubt that the
culprit is the power supply. The Zero W seems to be a very flaky device
in terms of power supply.
A powered hub should fix that, when a device is plugged directly into the
raspberry pis usb (IIRC only 300mA is available) it can cause reboots.

Oh yes, that would be a right technical fix for the problem but it's a
bit of an aberration in terms of cost and size to use a powered HUB with
its own power supply to fix a little thing like the ZeroW, you know.... ;-)

Just use the hub to power the Pi. I used to do that wit the Pi1 and 2.

have fun


Just want to share with you that TP-LINK TL-WN725N works very well with the raspberrypi Zero W.

I have been downloading many times the same 3.6 GB file from the internet with no failures just for testing. I have made a CVS checkout of the base system source and pkgsrc source fine.

Also have watched a 1h 30 m film using minidlna server in VLC over the local network with no failures at all.

With bwfm driver that was just impossible.

Great work!
