A message popped up on my Andoid phone that someone was hacking my home network so I changed the WiFi password on the Router and then the SSID, and, in addition, stopping the broadcast of the SSID at that point.
The new SSID is accessible with the new password but the old SSID still seeme to be available.
The network is from a Netgear N300 Router and extended by TP Link AV600 Powerline units.
I cannot seem to find where the old SSID is coming from. The WiFi signal for the old SSID seems to better in the room where the TP Link WiFi unit is the main signal source.
Has anyone got any ideas how I can remedy this?
