Wireless network conectivity

I bought one of these about 12 mths ago: http://www.jaycar.com.au/productView.asp?ID=YN8306&keywords=high+power+wireless+n&form=KEYWORD

I downloaded the drivers from the link above then installed them on a windows computer. How do I use these linux drivers/installers on the raspberry pi to get the wireless adaptor to work?

Will this work with the Raspberry Pi?

If your adaptor uses Broadcom chipset you may need to install a piece of firmware to make it work. I had a similar problem with my Linux netbook that had Ralink wifi. It booted up but said that there was no WiFi as no firmware was loaded! After much searching the solution is at http://linuxwireless.org/en/users/Drivers/b43.

The B43 package installs the firmware needed to run the Broadcom chipset. As its not GPL it can't be released with any Linux package, but is able to be extracted from the Windows driver. This package is already to go, just install!

I required the firmware-b43-installer package. Not sure if it's in the RasPi repositories as I haven't got mine to play with yet... :-( But the above site it fairly comprehensive!

Hope it works.

i have had issues with broadcom on various laptops using different distro's of linux, this is the best solution i have found so far. i also cant confirm at the moment if the b43 firmware is in the repositories. i will check tonight and see if it is.

i cant actually try this on the R-Pi as i dont have a USB wifi adapter with the broadcom chipset.

hope this helps.

Hello Fergus, i'm afraid as I said above, i'm very much a Linux noob too, and other than looking like those instructions are for re-compiling the kernal with the drivers included (and even that is probably wrong) I can't help much
All I can say is that to get my USB stick working, I didn't have to do any this, just the instructions I posted a way back up this thread. I think there must be an easier way than doing the above.

I bought the Edimax EW-7811Un but I need help setting it up, Steve, could you please help me with this one. The RPi wiki says that it is verified but there is no guide to set-up this device for Raspbian. I found this guide: http://www.ctrl-alt-del.cc/2012/05/raspberry-pi-meets-edimax-ew-7811un-wireless-ada.html but it has not worked for my RPi. I think it has something to do with me not being able to get the rpi-update thing. I tried to get this but failed. Everytime I run rpi-update it returns:

/usr/bin/rpi-update: line 1: syntax error near unexpected token `newline'
/usr/bin/rpi-update: line 1: `<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Trans itional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">'

Can this be fixed so that I can update the firmware?

Wireless card help would be nice as well .

I noticed from the link that Edimax uses the rtl8192cu driver. I have another adapter (Asus USB-N13) which uses that driver and it did not work by default with the current Raspbian Wheezy image. However, it did work ok with Adafruit's new image as it includes that driver, so you may want to give that a try: http://learn.adafruit.com/adafruit-raspberry-pi-educational-linux-distro/occidentalis-v0-dot-1

With the EDIMAX, it gives me the errors:
8192cu: disagrees about version of symbol <name of part>
8192cu: Unknown symbol <name of part> (err -22)

The "name of the parts" are all different.

What can be done to fix this issue? This might sovle my problem.

How do you unpack a .ko file?

I didn't unpack mine. this could be leading to the above issues.

I do not really want to change image (right now). But I might give it a go in the future.

Right now though, I just want to get this adapter working.

My guess is that the 8192cu.ko module you have doesn't agree with the version of the kernel your running. a .ko file is a kernel module file and shouldn't have to unpacked. the utility "modinfo" will print out information about the module. could you run that and paste the output? also, could you paste what "uname -a" outputs? it might be that the kernel versions don't agree.

Hey drew,

I installed Occidentalis v10.1 successfully onto my Raspberry Pi's SD card and went to /etc/network/interfaces to add my SSID and password where it wanted me to add it. But for some reason I still can't connect to the Internet wirelessly when my wireless dongle is connected in (I'm using the Zyxel NWD2105 which uses Ralink firmware). When adding my SSID do I keep the quotation marks so it's SSID "xxxx" or do I remove the quotation marks? Is there anything else I must do to get my dongle working?

Hi Ahmad,

I believe you should keep the quote marks. An alterative to configuration via /etc/network/interfaces would be to wicd which is a GUI network manager that allows you to configure your wifi adapter. You should be to install it by entering into the command line: "sudo apt-get install wicd" (while connected to Internet via Ethernet). I wrote up more detailed instructions in this comment before:

http://www.element14.com/community/docs/DOC-44703/l/raspberry-pi-wifi-adapter-testing#comment-15744

I didn't try to install wicd it on the Adafruit image yet, so I think I'll give it a go this weekend. I had installed wicd on the "official" Raspbian Wheezy image and it worked well.

Cheers,
Drew

Okay, thanks for the help, I really appreciate it Drew and I'll give this a go next time I hook up my Pi up to the internet. Hopefully it will work on adafruit's image because I didn't have much luck with it on Rasbian Wheezy, but it's worth a try.

Edit - Using the WICD software on the adafruit's image I successfully managed to connect to my router using a dongle. Thanks for the help, my Raspberry Pi can now connect to to the internet without an Ethernet cable (which has been an issue to me for quite a while)
