Deco M4 v2.10.4 with WPA2-PSK [AES] security.
 

Tonight a new device popped up on my network.  The MAC address said Azurewave.  I blacklisted and deleted it but about 15 minutes later it reappeared.  I deleted it and it kept reappearing multiple times.  Eventually I changed my network password and it has not been back since.

 

Any ideas on this?  If someone was trying to hack my network would they have to be within range of my SSID signal?  Wouldn't they need my password?  I have a shifty neighbor who probably knows enough about computer networks to try something like this.

Hi, thank you very much for your feedback.

The password is always necessary for all conditions and a complicated one Is always recommended.

Currently, many wireless devices improve privacy by using a different MAC address for each Wi-Fi network.

So that might explain why the device could connect to your Wi-Fi even though it has been blacklisted.

FYI

Azurewave are Wi-Fi NIC device manufacturer in Tiawan. These devices are used in any number of computing and IOT devices. So it may have even been something as innocuous as a Google Streaming device or your neighbor's notebook computer. 

 

But yes as you found out by changing your password, you neighbor had to have had your Wi-Fi password to connect to your Wi-Fi ! 

Good thing you changed the password.  

 

And as TP-Link stated,  please ensure your Wi-Fi password is very complex and not easily guessed.

@DAServices After I changed my password the Azurewave device reappeared.  I blacklisted it and it has not come back as of now.  I had something similar happen once with my Brother printer.  An unknown device popped up that turned out to be the internet connectivity module of that printer.  But this time I have not added any new devices to my network in months and then all of a sudden this Azurewave device pops up.  I read that Azurewave is used in certain IoT devices.  I have a smart doorbell and a smart garage door opener.  But both of those devices have been on my network for over a year with no sign of Azurewave until now.  Is it possible that one of these device manufacturers did some sort of update that caused the Azurewave issue?  
 

There's no way someone would have known my new password so quickly after I changed it.  I suspect this is somehow related to a device already on my network that uses Azurewave technology, but do not understand how it would go unseen for so long.

Same here. Noticed that new device joined the network.

 

Hon Hai Precision Ind

 

Blocked it for good measure.  Checked the MAC, and it turned out to be my PS4.

 

For some reason, the DECO sees the manifacturer of the equiptment and not the name (?)

 

So, it would help remembering if anything new was connected to the wifi and then check the MAC (older devices cant change this, unlike new ones that can randomize)
