I'm using RAlink device, Right now i'm at school with a lot of wifi spots with 802.1x authentication.

And i'm getting these results after a scan.
wifi -i ra0 scan

Hey! Thanks for the bug report. I'm in the middle of finals, but I think I
could take a look at this after my tests.

Hi @jargij,

I have finally had some free time to work on this. I fixed the bug in 22c10be and have released a new version of wifi (https://pypi.python.org/pypi/wifi/0.3.2).

I'm really sorry that it took so long to get to. I have been travelling lately and just haven't had the time to get around to it. I hope it's not too late.

I'm going to go ahead and close this bug out. Please reopen it if you run into any more problems.

Are you manually feeding the output of iwlist scan into the parser?

Does this happen from the CLI?
