I have build and installed the Realtek driver (92ce_se_de_linux_mac80211_0005.1230.2011.tar.gz) and im getting *11* wifi networks against *3* wifi networks detected if using the driver from latest kernel (version 3.3.5). I know what Larry said but the differences are obvious and many, so the fix that was commited in rtl8192ce maybe needs to be reviewed, will someone listen please?
