Re: Debian Netgear (RTL8187)

Thu May 10, 2012 8:23 am

I didn't want to post another message about Wifi adapters, but I'm struggling (i've spent 2 days googling)!!

First off, I get most success when only the Wifi dongle is connected (no keyboard or mouse). Once plugged in the dongles blue LED does flash away quite happily. I tested the dongle on a windows box and it does work.

lsusb:

Bus 001 Device 008: ID 0846:4260 NetGear, Inc. WG111v3 54 Mbps Wireless [realtek RTL8187B]
(is the B in RTL8187B significant?)

iwconfig returns wlan0 in the list of adapters (so I'm assuming the driver is installed?? when a mouse/keyboard is plugged in, I don't get wlan0 in my list!)

I set the channel that my AP is on

sudo iwconfig wlan0 channel 11

wlan0     IEEE 802.11bg  ESSID:off/any
Mode:Managed  Frequency:2.462 GHz  Access Point: Not-Associated
Tx-Power=20 dBm
Retry  long limit:7   RTS thr:off   Fragment thr:off
Power Management:off

I then hope to go to:

sudo iwlist wlan0 scan

and see a list of wifi networks around my house, but I get:

"wlan0     No scan results"

I added a few "bits" in to: /etc/network/interfaces as per other forum suggestions, but it made no difference.

I'm powering the Pi off an Apple 3 pins to USB which supplies 5.13volts, but I can't find its current rating.

I've placed the dongle in various distances from the AP.

I hope I'm missing other settings, but I have no clue as to which ones.

thanks in advance.

Yes a lot of us have had problems,  try searching the Troubleshooting forum for 'wifi' or 'wireless' and there are many recent posts on this.  There seem to a number of problem areas :-  firmware , debian patch,  USB Hubs and power feed to the adapter when attached directly.  Try these links

thanks for response, guess I should have expected "search the forum". I searched specifically for my chipset, and didn't think the solution would be as drastic as it is.

will give it a go today.

thanks again.

Do we think with an updated Debian distribution, the existing drivers will work (I'm not confident in taking drivers from github and updating) or will the drivers need re-compiling too? I'd expect that once drivers are compiled for ARM, then they are compiled?

I don't really know.

thanks

I also have netgear w111v3 adapter but when I connect to my pi I dont even gat the blue light to flash.
if I do lsusb I cant see the device. I am running squeeze.
Can anyone help me get up and running? I connect the Ethernet cable and no problem.

If you could send instructions via this post or email to [email protected] I would be grateful.

I think your problem ( i am only guessing) might be a power problem.
I had problems with power when I used a 500Ma power supply. The keys on my keyboard kept repeating, then I noticed that the netgear w111v2/3 requies 500Ma of power see here http://wireless.kernel.org/en/users/Drivers/rtl8187
so at a guess it might be that when you plug in your keyboard / mouse along with the adapter you do not have enough power to use all devices. As I said this is only a guess.
you could also look here: this highlights keyboard / mouse / usb issues.

Hey,

Following up here 'cause I recently had the exact same situation. What geezbeez is seeing is low power which I had with the WG111v3 even when using a 2A supply.

If lsusb and/or dmesg are showing that the dongle is being detected but 'sudo iwlist wlan0 scan' shows no networks then this is the likely cause. I switched to a powered hub and started working just fine.

If you want to keep it neat and use a dongle that doesn't require a powered hub then many of the newer nano size dongle seem to work. The Edimax EW-7811Un works out of the box plugged directly into the RPI USB port for me (using a Nexus 7 power supply).

BTW.. I found this page to be most useful when setting up WiFi the most straightforward and works fine for me (Raspbian): http://learn.adafruit.com/adafruits-ras ... cidentalis

Good luck..

I just used the link on an otherwise unresponsive WG111v3 Netgear dongle that I'm trying to configure to get the Pi away from the eth wired router connection, I typed the shorter [not hidden SSID] and I'm now tightvnc viewing it :) just getting the resolution right, then taking it somewhere else for flatbed scanning jobs using 32-bit hardware on 64-bit systems. :lol:
