usb wifi 802.11b/g/n module with antenna

by Leif_Farr on Sun Sep 29, 2013 4:35 pm

Using the usb wifi module with antenna, plugged into a usb hub, (not powered) that is plugged into the Rasberry Pi (B), cannot seem to get a connection to the router. It seems that the Rasberry Pi does not recognize the module. I tried the following

sudo nano /etc/network/interfaces

auto lo
iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
auto wlan0

iface wlan0 inet dhcp
wpa-ssid "ssid"
wpa-psk "password"

hit control x
hit y
hit return

I tried sudo ifconfig and it does not list an ip address for the Pi

This is all new to me, so any help would be much appreciated - thanks

You have filled in the actual SSID and password of your own router here?

What do you get from these:
Code: Select all | TOGGLE FULL SIZE
ifconfig -a

Code: Select all | TOGGLE FULL SIZE
iwconfig


You may need to use a powered hub.

Hello and thanks for the reply. Yes I did input my modems ssid and password in the correct sections. When I used ifconfig -a I got the following results:

etho Link encap:Ethernet HWaddr b8:27:eb63:7b:8c
UP BROADCAST MULTICAST MTU:1500 METRIC:1
Rx packets:0 errors:0 dropped:0 overuns:0 frame:0
Tx packets:0 errors:0 dropped:0 overuns:0 frame:0

Typing in iwconfig gives the following results:

lo no wireless extensions

etho no wireless extensions

So you're not talking to the thing at all. What happens if you plug it directly into the Pi?

Hello - I tried plugging the module directly into the Pi, (instead of the usb hub, non powered) - could not connect to modem. I tried ifconfig -a and iwconfig and the results were the same as in my previous reply.

OK - let's try replacing it. Please email support@adafruit.com with a link to this thread and ask for a replacement.

Hello
I e-mailed support and asked for a replacement as suggested. I did have a couple of questions. Should I have tried using a powered usb hub? I tried plugging the wifi module directly into the Pi, however I still had the usb hub plugged into the Pi's second usb port to run the keyboard and mouse? Secondly the module came with a small disk that contained a driver, was I supposed to have installed a driver for the module or was that just for Window OS? It seemed from the information that I was able to gather that using this wifi module with the Pi was a plug and play situation with the one task of modifying the file and putting in the ssid and password, is this correct or am I missing something?

An unpowered hub is essentially useless with a pi, since the pi can only supply a very limited amount of power to USB.
You definitely should give the dongle a try without anything else connected to USB.

Hello again
Well, I tried the module plugged directly into the Pi's usb port for the second time, I also unplugged the usb hub and then just plugged the mouse into the Pi's second usb port so that I would have a way of logging out of the Pi. Still the same old problem, not connecting to modem and not recognizing the module.

Hello, I am experiencing the same thing but my dongle does not have an antenna. I am running Occidentalis 0.2 on a model B Raspberry Pi with Hynix memory. I noticed at boot time if gives an error message "ignoring unknown interface wlan0:wlan0." I have tried a distribution upgrade as well as adding
deb http://ftp.us.debian.org/debian wheezy main contrib non-free
to /etc/apt/sources.list

I am wondering if a driver for my USB dongle is missing from the Occidentalis distro. I built the Raspberry Pi WiFi Radio according to your learn.adafruit.com tutorial and used Raspbian Wheezy 05-25-13 release and the dongle works fine when plugged directly into the Pi.

Here are some outputs from my device.

Which dongle do you have? Did you get it from us?

This is what you should get via 'lsusb' if you purchased any of our WiFi adapters

pi@raspberrypi:~$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 004: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter

of course, if you bought it elsewhere, we can't help or support. the 'rtl8188CUS'/'rtl8192' modules are well supported by raspbian & occidentalis.

Hello,
I didn't get the dongle from you unfortunately but the dongle works under the standard Raspbian Wheezy 05-25-2013 distribution. I assumed that Occidentalis 0.2 would have driver support for the dongle since it is a Raspbian derivative. Sorry if this should have been under a new thread.
