Nokia N900 WiFi Setup/Keyboard layout issue

WiFi

When I run

$ sudo ip link set wlan0 up
$ sudo iw wlan0 set type managed

$ sudo su -
# wpa_passphrase $YOUR_SSID > /etc/wpa_supplicant/wpa_supplicant.conf
<enter passphrase here and press Enter>
# exit

I get the following error

rfkill: cannot open RFKILL control device

checking on the upper right corner it says

W:down

hinting that no connection has been made.

Keyboard Layout

When in a terminal, on X11, I get a non documented layout. Not logging into X11, the keyboard works as shown on the N900 pmOS wiki page. Which I find weird. I ran

$ apk add kbd kbd-bkeymaps
$ loadkeys -b rx51_us.map > rx51_us.bmap
$ gzip rx51_us.bmap

sudo setup-keymap

and nothing changes. A few errors are displayed, all concerning my network issues (as explained above)
