Hello Nat,

Thanks for your great explanation, I understand. I then abandon the 
tests with the 8188FTV and wait for your improvements. They will be 
appreciated. I cannot fix anything, the driver world seems to be a hell! :-)

I have just received today from Amazon a TL-WN725N USB WIFI adaptor and 
it just work in the raspberry Pi Zero W:

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.

I am going to test it during several days to see if it works better than 
the flaky bwfm driver for the built in WIFI.

I do not know if I have to  disable the bwfm driver to avoid any 
interaction or I can leave it as is.

Thanks so much.
Ramiro.
