Wifi and NETGEAR N150

Help and Support Help
1

Hei,

Does anyone know how I can get volumio working with the Netgear 150 wireless USB adaptor ?
I plugged it in, configured it in the web gui but it does not appear to connect. The web gui shows now IP address on the wlan0 interface and if I unplug the cable I cannot access the PI.

There does not appear to be any error message anywhere that I have managed to find (I am not an expert PI user).

If I ssh into the PI and run dmesg I can see:

usb 1-1.2: new high-speed USB device number 4 using dwc_otg
usb 1-1.2: New USB device found, idVendor=0846, idProduct=9041
usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1.2: Product: 802.11n WLAN Adapter
usb 1-1.2: Manufacturer: Realtek
usb 1-1.2: SerialNumber: 00e04c000001

So it appears to be detecting the adapter.

If I run “ip link show” :

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000
link/ether b8:27:eb:e8:e5:16 brd ff:ff:ff:ff:ff:ff

I cannot see the wlan0, so I think there is a problem somewhere … but where.

I have looked at the automatic script written by MrEngman, but when I run it I get:

"An RTL8188CUS driver module is installed but is not loaded.

You have 1 wifi adapter configured.
wlan0 is configured but is not installed.

The Pi has an internet connection.

Any files needed for the installation/upgrade will be downloaded from the
Internet unless they have already been copied to the SD card /boot directory.

Unrecognised software version: Linux volumio 3.8.10+ #1 PREEMPT Mon Oct 21 10:36:33 CEST 2013 armv6l GNU/Linux

Downloading the latest script.

The script you’re using is the latest version.

Aborting the rtl8188cus installation script."

Reading around a bit, it appears that the script should no longer be needed since the correct drivers should be included in the base image.

Anyone have an idea why it is not working, or any help in investigating how to get it working ?

Thanks
Ian

Reboot the PI, without Ethernet. It should work!

3

A reboot does not appear to help, with or without the cable attached.
And of course when the cable is not attached I cannot contact the pi to see what has happened !

How can I debug this ?

4

If you reboot with cable connected? Can you see the Webui? If yes, does wlan0 has an Ip?

5

If I put the cable back in, I can connect again and then the wlan0 still does not have an IP.
Is there anyway I can see a log from the attempted WLAN connect to see what is failing ?

6

I have also set up an open WLAN and tried to connect to that.
The problem now is that when I try and change the wlan network settings the webUI says “Netconfig saved” but displays the old values. I have even tried the “reset to default” option but it does not appear to work.

Looks like I am going to have to try and burn a new image and start again :unamused:

New image burnt.
When I try and save wifi settings, nothing appears to be saving. There seems to be a problem with the WebGUI showing the values in FireFox on Ubuntu, but when I look in Safari on an iPhone there are no values saved. Adding values in Safari also does not save them dispite getting the “Netconfig saved” message. No other error message is visable.

Same values in “dmesg” and “ip link show” - no wlan showing.

Rebooting does not help.

After saving the wifi settings, can I check anything through “ssh” to see the saved config ?

Is there any logging anywhere ?

Quickly losing faith …

To see if your wlan is recognized, just type in ssh

ifconfig -a

mine looks like that:

If you can’t see wlan0 this means you got problems with the driver being loaded… I already installed firmware-realtek… but you can try reinstalling with

sudo apt-get remove firmware-realtek sudo apt-get install firmware-realtek

If this doesn’t work, we have to look on how to enable your specific dongle with proper driver

Still no wlan0

Anywhere else I can check to see if there is an error message to explain why the wireless USB plus is not loading ?

Hi,

try

modprobe rt2800usb .

I have Ralink RT5370 802.11 b/g/n, and I use this setup:

[code]root@volumio:~# cat /etc/network/interfaces
auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

auto eth0
iface eth0 inet static
address 192.168.0.201
netmask 255.255.255.0
gateway 192.168.0.1[/code]

[code]
root@volumio:~# cat /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1

network={
ssid=“ssid_name”
psk=“password”
scan_ssid=1
proto=WPA2
key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIP
id_str=“Volumio”
}[/code]

And I also used ifdown and ifup on wlan0 for restart, but wlan0 is working well after that… actually I had to use wpa_supplicant.conf, because with RT5370 I had a problem to connect to hidden SSID, with this setup, it`s working well.

Hi ronnicek,

Thanks for the suggestions.

I tried “modprobe rt2800usb”.
I am not sure what this should do, you do not mention anything in your post. The command ran, but did not give any output.

If did not have any other visable effect on the setup either.

I do not know much about Linux, but I assumed that you wanted me to manually update “/etc/network/interfaces” to have similar settings to yours.

[code]root@volumio:~# cat /etc/network/interfaces
auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet dhcp

auto eth0
iface eth0 inet dhcp
[/code]
I did not add the section about “/etc/wpa_supplicant/wpa_supplicant.conf” as I do not have a hidden SSID.

After a reboot, this still did not appear to have any effect.

root@volumio:~# ip link show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000 link/ether b8:27:eb:e8:e5:16 brd ff:ff:ff:ff:ff:ff
I also tried “ifup wlan0”

[code]root@volumio:~# ifup wlan0
Internet Systems Consortium DHCP Client 4.2.2
Copyright 2004-2011 Internet Systems Consortium.
All rights reserved.
For info, please visit https://www.isc.org/software/dhcp/

Cannot find device “wlan0”
Bind socket to interface: No such device
Failed to bring up wlan0.
[/code]
But that did not appear to be successful.

However when I go back to the network page of Volumio.local, I now get this:

Pressing “Manual Edit” does not seem to help.
Pressing “Reset Network Config” appears to update /etc/network/interfaces and removes the wlan0 section that I added.

Any other ideas ?

Could you give me output of lsusb command?

Hi…. I too experience no WiFi on Volumio 1.1beta using the WebGUI. I am using the Edimax EW-7811Un USB WiFi dongle. I believe the problem not to be the Netgear N150 adapter, but an issue with this build. I have found two solutions that are a work around for the problem. One is to manually edit the /etc/network/interfaces file with appropriate WiFi wlan0 entries. I do not recommend this solution as it is not the optimum way to assure a solid solution. Do try:
Wi-fi on Raspberry Pi, a simple guide
raspyfi.com/wi-fi-on-raspber … ple-guide/

Quoted from the guide do check out the guide using the URL above
If you’ve not installed Wicd-curses just type:
sudo apt-get update
sudo apt-get install wicd-curses
Ok, now we are ready to start, type:
sudo wicd-curses
You’ll get a list of the wireless network found by the Raspberry PI

Now, you can select your Wi-fi Network, just highlight it with arrow keys and press right arrow key to edit its properties:

When you’re done, just press F10 to save, then it should connect!

Let me know if this helps you as it did work for me on the Raspberry Pi. I hope for a future WiFi fix that allows us to use the WebGUI.

Hi Tracer5,

Thanks for the tip, but I think my problem is lower level than yours since when I install and fireup wicd-curses it shows no wifi networks. I think this must be because I have no wlan0 available.

Hopefully someone will be able to tell me how to get wlan0 installed and configured.

∕Ian

Hi Lan
Looks like you are correct. When wicd-curses does not show any WiFi entries there is a low level problem with your WiFi adapter or driver.

My WiFi dongle is:
EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS] - (Edimax Technology Co., Ltd)
Your WiFi dongle is:
802.11n Netgear N150 chipset is Realtek RTL8188CUS.

Module rtl8192cu supports:
Realtek chipsets (RTL8188CE-VAU, RTL8188CUS, RTL8192CU)

Wicd-curses may not see your adapter. Please:

sudo wicd-curses
then press P (that stands for preferences). You’ll find that there’s a field called wireless interface, which if empty. Just write wlan0
in it. Then F10 to save.

Good, then lsmod command? :slight_smile:
