Well now I'm having this problem as well. Any works, my_ap does not. I have no idea what could have changed since it was last working.

...also I accidentally sent a blank reply to this thread, oops.

I encounter the same problem with my wifistix.  If I use:

   iwconfig mwlan0 essid "my_ap"

I get:

  Error for wireless request "Set ESSID" (8B1A) :
  SET failed on device mwlan0; Network is unreachable.

Even though all of my other PC's can see the AP just fine.

Then if I do:

   iwconfig mwlan0 essid any

It connects up fine.  However, this is unacceptable solutions since
"any" will often allow the wifistix to associate with an AP other than
"my_AP".

Congrats! :o)

Thanks, but I did have the txpower param in there. I got it to work with
"essid any", but not with my AP's essid (ZyXEL_bEO - maybe the
underscore is messing something up).

So, for me - this doesn't work:
iwconfig mwlan0 key xxxxxxxxxx key open essid ZyXEL_bEO txpower 100mW

(and yes, it's the correct essid, copied and pasted from "iwlist scan"
:o)

but this does:
iwconfig mwlan0 key xxxxxxxxxx key open essid any txpower 100mW


I don't worry to much about it atm since "any" seems to work fine.
