Unable To Connect to WiFi on RPi3

Postby cachedrive » Sat Jan 07, 2017 5:07 pm

I installed ALARM Arch 32-bit which by default installed wpa_supplicant and iw.

I can see my device is listed / recognized when I do:
$this->bbcode_second_pass_code('', '[root@rpi1 ~]# ip link | grep wlan0
3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000')

I attempt to bring it up (however it appears to never go UP):
$this->bbcode_second_pass_code('', '[root@rpi1 ~]# ip link set dev wlan0 up
[root@rpi1 ~]# ip link | grep wlan0
3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000')

When I scan for SSID's using the wlan0 adapter, I can see plenty of hot spots:
$this->bbcode_second_pass_code('', '[root@rpi1 ~]# iw dev wlan0 scan | grep SSID
SSID: BHNTG1682GF492
SSID: BHNTG1682G0862
SSID: BHNTG1682G0C84
SSID: \x00\x00\x00\x00\x00\x00
SSID: DIRECT-C8-HP OfficeJet 3830
SSID: BHN 1008
SSID: NETGEAR84
SSID: BHNTG1682GC692
SSID: TITO2')

I'm not sure what I'm doing wrong in attempting to bring this interface 'UP' and connected to my Wi-Fi (WPA2 encrypted LAN). Can you guys let me know what I'm doing wrong or missing?

You are looking at the wrong part
$this->bbcode_second_pass_quote('', ' ')<NO-CARRIER,BROADCAST,MULTICAST,UP>

It says UP at the end of the string. But you are not connected to anything. So the LINK is down, not the interface.

You can use wifi-menu and netctl to make it easier to connect to wifi.

You can also install ifconfig (part of net-tools package) and compare outputs of ip and ifconfig to learn the difference if that would make it easier for you.
