Wifi Trouble Shooting
« on: September 25, 2005, 01:26:35 pm »
I'm trying to troubleshoot getting wifi working on my SL-5600. I'm running the stable version of 3.5.3. In addition to the log information below, I've included a screenshot of my network settings.

Running cardctl ident on the Linksys results in

Socket 0:
product info: "Linksys", "Wireless CompactFlash card", "", ""
manfid: 0x028a, 0x0673
function: 6 (network)
Socket 1:
no product info available

Here is the system information log when booting with a linksys card plugged in (this is from where the card detection kicks in) It looks like there's trouble pretty early on where it says "<4>Internal error: Oops: ffffffff"

Wifi Trouble Shooting

Someone from the OpenZaurus mailing list helped point out that when a WiFi card is plugged in and in Nework Settings you click "Configure" for the wlan0 interface I should find several options like setting the ESSID. Clearly I'm not getting to that stage yet.

I've attached a screen shot of what I get when I try to configure wlan0. This is after a clean boot and then an insert of the linksys card. Here is what dmesg has to say after the card was inserted:

hostap_crypt: registered algorithm 'NULL'

Much appreciated,

Solved.

John on the OpenZaurus list suggested checking the MD5Sum after transfer to the compact flash card. Bingo! Wireless - it just works :-)
