WLAN USB Stick

[admin]

Meteohub on SheevaPlug can make use of WLAN USB sticks. Update 4.4a will support the following sticks (tested with 802.11g, WPA):

1) SMC EZ-connect g SMCUSB-G (zd1211rw chipset)
2) D-Link DWL-G122 (rt73 chipset)
3) "non name" (Realtek RTL8187B chipset)

Remarks:
- All of these are cheap and should be easy to get
- Sticks from other sources with the same chips should do as well
- Realtek stick has poor throughput
- D-Link comes with practical stand (see picture)

Hello Boris,

What stick has a good throughput?

Thanks,

The SMC and D-Link sticks above are working well.

May be "throughput" is not the right word, but the Realtek equipped gives quite some waiting time when working with web interface of Meteohub. I don't know if it is just the particular "no name" stick or some compatibility thing with my WLAN router or if the Realtek chipset is in general not working that well.

Have tried two different D-link dwl-g122 usb sticks without any luck. I do not know the chipset..

What does not work in detail? Please try these steps:

1) connect usb WLAN adapter and reboot metehub
2) goto "network" page, select "wlan" radio button, press "save" and reboot on "admin" page
3) select SSID of your router from drop down list on "network" page, select encryption mode, enter pass phrase, deselect DHCP for WLAN IP, enter static WLAN IP and press "save".
4) goto "admin" page and reboot. Disconnect LAN cable (otherwise Meteohub will work via LAN when rebooted, this allows to recover when a bad WLAN setting has cut you off).
5) After reboot, connect via WLAN IP.

When I connect the Usb-adapter the choice for wlan shows up.

I get as far as trying to select ssid in the drop down box, but no wlan shows up. My wlan is set to show ssid.

Have also tried to set ssid and password manually with no luck.

(Checking from console with ifconfig shows the address is set on wlan0. Dmesg shows the prism2 driver is loaded. I cannot find iwconfig or wpa-supplicant from the console.)

I'm also having problems - purchased a DWL-G122 but I can't seem to get it running - looks like it's revision E which is a different chipset.

Code: Select all

meteoplug:~# lsusb
Bus 001 Device 004: ID 0fde:ca01
Bus 001 Device 003: ID 07d1:3c0f D-Link System AirPlus G DWL-G122 Wireless Adapter(rev.E) [Ralink RT2870]
Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I've copied across the rt2870 firmware, and it appears to load, but no success at getting it attached to my wireless network. After a bit of googling it looks like it's not working quite right and I need to recompile the module (http://art.ubuntuforums.org/showthread. ... v.E&page=2 is where I was heading with this).

Sadly I don't seem to be able to install the kernel headers to be able to compile the driver - I'm fairly comfortable with linux and kernel building etc, but I'm more of a redhat kind of guy.

Coupled with running on a plug - I can't quite figure out why apt-get install won't install the headers - I get the following when I try.

Code: Select all

meteoplug:~# apt-get install linux-headers-2.6.32-5-kirkwood

The following information may help to resolve the situation:

The following packages have unmet dependencies:
  linux-headers-2.6.32-5-kirkwood: Depends: linux-kbuild-2.6.32 but it is not installable
E: Broken packages

I get that kbuild is'nt installable - but is there a way forward (or am I heading in the wrong direction).

Very impressed with everything else so far though - assuming I can get this working I'll get a license.


Cheers
