If your wifi is not working anymore, you probably use a JVH based ROM and have restored your wifi settings via titanium backup (or possibly other backup utilities). Wifi configuration from pre-JVH is not compatible with JVH ROMs. You should be able to restore without reflashing a full ROM by stopping wifi, then doing the following commands in a root shell.
cd /data/wifi
cp bcm_supp.conf bcm_supp.conf.bak
cp wpa_supplicant.conf wpa_supplicant.conf.bak
rm bcm_supp.conf
ln -s wpa_supplicant.conf bcm_supp.conf
cat bcm_supp.conf.bak | head -n5 > wpa_supplicant.conf
cat wpa_supplicant.conf.bak >> wpa_supplicant.conf
rm wpa_supplicant.conf.bak bcm_supp.conf.bak
And enable wifi again
