# SSID is different from the OpenWrt default!
#
# This happens during upgrade in two cases:
# 1) if the user had previously customized the SSID;
# 2) if the user was already using our custom image with SSID
# "rezine.org". He/she may have changed the password and channel,
# and we have no way to check that.
#
# In both cases, we don't want to touch anything.
