Model: Deco X55  
Hardware Version:
Firmware Version:

After a few months of use, I noticed that one of my three Deco units was showing it's factory name instead of my SSID, and no lock, when looking at the list of available networks on my phone. After the shock wore off, I clicked on it with my iPhone but it wouldn't connect. I unplugged the unit, waited a few minutes and plugged it back in. It then disappeared from the list so that only my network SSID shows in the list. 

 

Is it likely that this one Deco unit is faulty? It's been about a week. 

Since I couldn't connect to it with my iPhone, is it unlikely that a neighbor or other person could have hacked my network? 

Should I change my network password and reset my dozens of client devices? 

 

I'm trying to map all the network clients and there are at least six that I can't identify. I've blocked them, but I'm naturally concerned that they're not in the house. 

 

Many thanks for help. 

DG

  @dgerety,

Do you happen to recall what the LED indicator status was when the default SSID was broadcast? 

When the Default SSID is shown, it is usually an indicator that the Node is in setup mode and not connected to the rest of your network. For a device to connect to the main network and connect to the internet, it would still need to be given addresses and credentials from the main deco unit - which wouldn't be possible if the device is in setup mode; especially since the problem deco did not have the credentials for the network available to it (or else it would have resorted to a wireless backhaul).

 

 

As an FYI, you may be surprised by some of the clients in the list - such as other decos or switches possibly appearing depending on your configuration. The extra devices could even be mobile phones or laptops set to connect with a Randomized MAC address.

 

As the devices have been connected, you will be able to see the MAC addresses of the devices in your client list. I would recommend attempting to look up what type of devices these are by using a MAC address lookup.

 

As it is unlikely that anything could have happened and so that you do not have to change your network password, I would recommend making sure that all of your phones and devices have Randomized MAC addressing or Private Addressing turned off so that your network can accurately track clients. This way you can determine if any new devices are connecting without your permission.
