WiFi on Pi3 / Arch [FIXED]

[cpcnw]

Just got my Pi3 and installed Arch according to the instructions at the ArchLinuxArm site.

Can anyone point me in the direction of the steps required for setting up a WiFi connection and making this the default?

Tia!

Will give it a shot after work

OK this is what I got up to;

1) Copied over the example

Code: Select all

/etc/netctl/ # install -m640 examples/wireless-wpa mywifi

2) I edited the profile 'mywifi' with my SSID and WiFi Key

Code: Select all

# nano /etc/netctl/mywifi

3) Shutdown wlan0 I/F as next step fails otherwise

Code: Select all

# ifconfig wlan0 down

4) Start wlan with mywifi profile

Code: Select all

# netctl start mywifi

5) Made this profile default at boot

Code: Select all

# netctl enable mywifi

This all works and I have a connection - however... looking through dmesg and journalctl I can see a few error messages - whilst the connection works I'd like to clear these up. Picking out just the items relating to WiFi...

Code: Select all

What's worse than error messages in log files is error messages that spew out across your terminal session?

I was getting regular two blocks of messages which included the line

Regulatory domain changed to country CH

I tried un-commenting my country 'GB' in /etc/conf.d/wireless-regdom but it made no difference.

After googling myself dizzy in circles I eventually removed 'crda'

My connection still works and the above has gotten rid of the frequent output

I still get the very seldom message about sequence numbers and the logs still do have various messages as per previous post but at least my wifi connection works
