Subject: RT2500 scan problem in 2.6.28

Hello,

I finally found a network where rt2x00 driver works reliably (using
2.6.27). However, it does not work anymore with 2.6.28.

The network uses hidden SSID so wpa_supplicant is configured with
ap_scan to find it. This works fine in 2.6.27 but the scan fails with
2.6.28. Rugging wpa_supplicant in debug mode tells the scan finds a
network with ssid='' and it does not match.

How can I debug it some more? I'm here with the network today and
tomorrow, then I will leav for home.

Official 2.6.28.

Oh, so this is known - I'll just wait for it to be merged upstream then.

Hi Meelis,
are you using the official kernel release or wireless-testing? In
wireless-testing there's included a patch for associating to hidden networks
when SSID=''. You can see the SSID value with iwlist <if> scanning.

If this is the problem I don't know how you were able to associate previously
with the 2.6.27 vanilla kernel.
