I've replaced '-Dwext' by '-Dnl80211'. The connection is still disconnected:

Code:

Next I modify my /etc/conf.d/net at suggested.

Adding 'rate_wlan0="5.5M auto"' to /etc/conf.d/net doesn't help.

samo ... the question was "[d]oes the log still show 'Driver did not support SIOCSIWENCODEEXT'" ... searching a little shows that some configurations are using nl80211 with carl9170 (though not necessarily your specific card), and we know that WEXT shows some errors, and now that nl80211 doesn't even find the device.

best ... khay

samo ... yes, we know that as we've already tried lowering manually this via iwconfig, as I said "I thought it worth mentioning" for completeness sake.

The log file doesn't show the message 'Driver did not support SIOCSIWENCODEEXT, trying SIOCSIWENCODE' any more.

From your .config:

Code:

CONFIG_CFG80211_DEFAULT_PS=y

I would try and disable powersave. Just a slight chance, but...

Deactivating CONFIG_CFG80211_DEFAULT_PS doesn't help. I get same debug output. Next I will try same kernel config with '-Dwext'
