Trying to connect to WiFi network on Raspberry Pi 0 using Ralink 5370

ScheissSchiesser · 12-16-2016, 12:30 PM

Hi all,

I worked my way through the Pi LFS guide, which supplements the LFS development guide. I am using a Raspberry Pi Zero v1.3. I am able to boot the system (Woo!) and I am now trying to get the WiFi connection set up.

I have followed the wpa-supplicant setup, and I have set up wireless tools. But I can't seem to connect to my router. I don't think it is even seeing any WiFi network. Here is where I am at:

Code:

# cat /etc/sysconfig/wpa_supplicant-wifi0.conf
network={
    ssid="NotYourWiFi"
    #psk="mypassword"
    psk=<the-hashed-password-i-think>
}

Code:

# cat /etc/sysconfig/ifconfig.wifi0
ONBOOT="yes"
IFACE="wlan0"
SERVICE="wpa"

WPA_SERVICE="dhcpcd"
DHCP_START="-b -q"
DHCP_STOP="-k"

Code:

# ifconfig

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Bcast:0.0.0.0  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:65536  Metric:1

          collisions:0 txqueuelen:1000
          RX bytes:0  TX bytes:0

Code:

# iwconfig

          Encryption key:off
          Power Management:off
          
lo      no wireless extensions

Code:

#ip link

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    link/ether 00:0f:60:05:1a:99 brd ff:ff:ff:ff:ff:ff

using wpa_cli to scan reports no results using scan_results. Something tells me my WiFi dongle is not working correctly or is not communicating correctly with linux. I am using the official raspberry pi linux 4.4 kernel.

Any help getting this working would be appreciated. Educate me please! I have exhausted my own knowledge at this point, and LFS and BLFS don't seem to have what I need.

Hi

Can you connect an eth0, Mine has trouble with wifi if eth0 not connected then see if wifi works, if it dose then at least you know you got wireless correct. It,s just something I found on mine

ScheissSchiesser · 12-16-2016, 01:07 PM

Hi Spiky,

No, I cannot test an eth0 connection, since the device does not have an ethernet port (it is a Raspberry Pi Zero). I have a WiFi dongle connected to a hub through the USB OTG port.

Thanks for the suggestion. Anything else I should try? It doesn't even seem to be able to find any wireless networks when I scan using the wpa_cli.

You have the firmware required

ScheissSchiesser · 12-16-2016, 01:35 PM

I think so, but I am not sure. How could I figure that out?

I placed rt2870.bin in /lib/firmware/. dmesg shows that it loads the firmware, and that the chipset is detected. It is using the rt2800usb interface driver. But it also says:

Code:

IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready

though I haven't configured IPv6 and I don't think I need to.

How can I confirm I have the correct firmware and that it is loaded properly?

spiky0011 · 12-16-2016, 02:09 PM

Have you tried restarting the network manualy?

ScheissSchiesser · 12-16-2016, 02:12 PM

What do you mean? Can you explain how to start it manually?

I assume you mean something more involved than ifup/ifdown. Those don't give me any obvious errors.

ScheissSchiesser · 12-16-2016, 02:36 PM

So something is definitely wrong with the firmware setup, but I can't really figure out what is wrong. Any help with debugging that would be great.

spiky0011 · 12-16-2016, 02:41 PM

not sure it is, Is that the only usb socket you have?

ScheissSchiesser · 12-16-2016, 02:43 PM

Yes. I have a 4-port USB hub with my WiFi dongle and keyboard attached.

spiky0011 · 12-16-2016, 02:56 PM

Is this a typo "wpa-supplicant-wifi0" should be wpa_supplicant

ScheissSchiesser · 12-16-2016, 03:24 PM

Yes, just a typo on the forum. It is correct on the Pi. Good spot though. I fixed it.

spiky0011 · 12-16-2016, 03:29 PM

as root

Code:

iwlist wlan0 scan

I suppose thats no output, struggerling here now

The wpa service script expects your wpa_supplicant configuration file to have the .conf extension.

These are the options I have for the same device

CONFIG_WLAN_VENDOR_RALINK=y
# CONFIG_RT2800PCI is not set
CONFIG_RT2800USB=m
CONFIG_RT2800USB_RT33XX=y
CONFIG_RT2800USB_RT35XX=y
# CONFIG_RT2800USB_RT3573 is not set
CONFIG_RT2800USB_RT53XX=y
# CONFIG_RT2800USB_RT55XX is not set
# CONFIG_RT2800USB_UNKNOWN is not set
CONFIG_RT2800_LIB=m

CONFIG_RT2800USB_RT53XX=y

lsmod
rt2800usb 14583 0
rt2x00usb 8338 1 rt2800usb
rt2800lib 68511 1 rt2800usb
rt2x00lib 34430 3 rt2800lib,rt2800usb,rt2x00usb
mac80211 477253 4 rt2800lib,b43,rt2x00lib,rt2x00usb
cfg80211 417021 3 b43,rt2x00lib,mac80211

Hope these help.

<NO-CARRIER,BROADCAST,MULTICAST,UP> means it,s up but not associated to a carrier access point
