I have replaced the old 11n wifi router (CISCO / Linksys) for the GC network with a new one with 11ac technology.
The new one is a 3band wifi router. Thus it has one 2.4GHz (11n) SSID and two 5GHz (11ac) SSIDs. All these have been set to be hidden. Just come to the 40m and find the necessary info for the connection.
Note that the user id / password for the admin tool have been changed from the default values.
