Raspberry Pi WiFi adapter testing

This document is linked from eLinux wiki page which lists compatible Raspberry Pi WiFi adapters:

http://elinux.org/RPi_VerifiedPeripherals#USB_WiFi_Adapters

It contains detailed information on WiFi adapters I have tested with a production Raspberry Pi:

UPDATES:

I recommend Raspbian "Wheezy" image as most WiFi drivers and firmware are included
For Realtek RTL8188SU based wifi adapters, Adafruit Occidentalis v0.1 image includes the 8192cu driver in the kernel

Asus USB-N13 rev B1

Newark SKU: 86R4501
USB ID: 0b05:17ab
Chipset: Realtek RTL8192CU [note: rev A1 is different]
Manufacturer product page
Test Results:
- Adafruit Occidentalis v0.1 image [tested 2012-Aug-07]
  - Adafruit's image includes kernel with 8192cu driver built-in so Asus USB-N13 works right away
  - Based on the current Raspbian Wheezy image with Adafruit's improvements
  - Discussion thread: Re: How to get Micronext mnwd152b working?
- The 8192cu had previously been compiled as a kernel module and offered for download (8192cu.ko) but this will not work on images with newer kernel like official Raspbian Wheezy. It must be recompiled from source for the specific kernel used in an image. Therefore, I would recommend using Adafruit Occidentalis for any adapter with the RTL8192CU chipset like the Asus USB-N13

Generic/"No-name" 802,11g adapter

A friend had this so I tried it out, it had no identifying brand name on it
USB ID: 148f:2573
Chipset: Ralink Technology RT2501/RT2573
Test Results:
- Debian (note: Raspbian has replaced Debian since my testing occurred)
  - connected OK with 802.11g AP in WEP mode
  - Warning: did not test with mouse in LXDE
  - Requires:
    - firmware-ralink package from squeeze non-free repo
    - otherwise you will see kernel error that the driver can't load the firmware
    - I recommend Raspbian "Wheezy" image as most WiFi drivers and firmware are included
- did not test with any other distros

  - connected OK to 802.11g WEP & WPA2 access point with wicd-curses
  - if already associated via wicd-curses, connections stays up when launching LXDE
  - however, fails to establish new connection in LXDE with errors similar to following in log:
    - kernel: smsc95xx 1-1.1:1.0: eth0: Failed to read register index 0x00000118
  - TP1/TP2 is 4.80V and all devices are connected to powered USB hub

yeah, I deleted mine first - I was loosing my train of thought and got side-tracked.

I'm guessing that if you get a bluetooth dongle that will work with Raspi then most any bluetooth keyboard will work with it -- does this sound right?

Drew is not, but I am!

(I went to edit my post, but appear to have deleted part of yours also... where you asked if we were both in England... unless of course you edited it first?)

Great Thanks Drew and David. I really like this keyboard and wanted to keep it so now it looks like I'll be able to.

Hi David,

I see that Drew got in before me, and I think he has hit the nail right on the head, as it were, and I am sure that doing what he has said will sort out the problems you are experiencing!

It is a good idea to check your 'locale' as well, while you are in that menu.

Good Luck!

David

Sounds like the keyboard layout setting. By default, it's a UK kb layout which is a problem for those not in UK. If you're running Raspbian Wheezy, then simple open the terminal and type "sudo raspi-config". Then select keyboard layout from the menu, and select the correct settings for your setup.

Hi David,

I got my K400 and for the most part its really nice. If I type in a quote( " ) on the keyboard though, I get an @. If I type in a vertical bar ( | ) I get some other character. Have you had this kind of problem before?

Cheers
David

Hi,

The K400 wireless keyboard and mouse worked fine with 2012-08-16-wheezy-raspbian.img right out of the box. I didn't have to connect it to a hub either. I ran into the running characters but I'm going to replace the batteries.

Thanks
David

Thanks... I have seen quite a few interesting looking products from Adafruit... but of course they are in the U.S.A and I am in the U.K. which poses a slight problem re shipping etc!

Looks like I'll be getting a keyboard today Looking forward to your 'noobies guide' since I am going to be getting an Asus

USB-N10 Wi-Fi adapter as well.

I don't know if you are still looking for PSU's but Adafruit has a 5V/1A power adapter

which is really 5.25v and from what I've been reading it seems to do the job nicely - so I ordered it. They also have a powered hub

rated at 5v/2A but the nice thing is they also have a power adapter rated at 5v/2A. For this one you just need an adapter if you

want to plug into the micro-usb port or USB-A.

Cheers
David
