long dmesg output, is something wrong with my wifi dongle?

Tue Jan 12, 2016 12:44 am

I'll just get right to it and post the dmesg output. You can find it here: http://pastebin.com/6TqEq9XN

I'm running a raspberry pi 1 model B, the kernel is 4.4.0 rc-8. Basically all I've done to this pi is go from a clean install of raspbian running 4.1.13+, update with the following commands, in order:

Code: Select all

sudo apt-get update -y
sudo apt-get upgrade -y
sudo BRANCH=next rpi-update
sudo wget https://github.com/porjo/mt7601/raw/master/src/mcu/bin/MT7601.bin -O /lib/firmware/mt7601u.bin
and then I configured /etc/network/interfaces and /etc/wpa_supplicant/wpa_supplicant.conf to connect to my wifi network.

What is my next course of action?

dmesg output is certainly a mess. I suppose there could be a problem with your wifi adapter, but there's the possibility of power supply issues to consider as well I suppose.

However, as you started with a Jessie image and set up your wifi by apparently editing both /etc/network/interfaces and /etc/wpa_supplicant/wpa_supplicant.conf it's possible that has messed things up.

With Jessie it is a bad idea to edit /etc/network/interfaces. Just set up the network editing /etc/wpa_supplicant/wpa_suplicant.conf and if you want a fixed IP for eth0 or wlan0 edit /etc/dhcpcd.conf.

Just tried 4.4.0 in a Pi 1 and the mt7601 wifi works fine using an Edimax EW-7711UAn v2. Connected straight away without any problems.

On my Pi /etc/network/interfaces is

Code: Select all

# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

auto lo
iface lo inet loopback

iface eth0 inet manual

allow-hotplug wlan0
iface wlan0 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

allow-hotplug wlan1
iface wlan1 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
and /etc/wpa_supplicant/wpa_supplicant.conf is

Code: Select all

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
        ssid="network-name"
        psk="network-password"
}

I really appreciate your replies Mr Engman, I only wish I'd gotten back to this thread sooner. I caved and just ordered the official raspberry pi usb wifi dongle.

I have one of those and don't like it. It does not have a LED to indicate it is connected/active.

If it's any consolation, neither does the one I have right now which isn't working.
