Re: Raspberry Pi Zero W almost useless

Hi,

There's a little more required to add support for the FTV variant judging by
changes made to openbsd's if_urtwn.c.

There's new firware that needs to be uploaded to the device.  And new power on
and rssi functions (It seems judging by the changes they've made it some what
is similar to the 8188EUS).

I'm going to see if I can get one of these adaptors on ebay.

I't will be awhile though before I try to get it working.

This is best done on the new wifi stack, so I doubt it will get backported to
-10.

In the meantime if you search for an 8192eu variant that will work with -10
and -9.

Best regards,

Nat

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.
