Sorry about replying in html format earlier. I've resent my previous
update in text only mode:
I already had the latest ipw2100 files - driver is 1.1.0 and the
firmware is 0.55. I took your suggestion and went and downloaded and
compile the wpa_supplicant 0.38 and still have the same problem. No
difference in the output.
The odd part is that all detected AP's have the 0 length for the wpa_ie
and rsn_ie. What do these values mean? What would be expected here?
