WiFi Network Name Changed after adding device MAC address

Earlier today I found a MAC address on my router MAC filtering list I did not add.  I am not sure if it is from our TV or not, but once I removed it, TV started acting a crazy. The only reason I caught this was because our network name had changed (it added a 5 at the end of the network name). So this evening I added the MAC address back....and again, it added 5 to the end of the network name and all devices (other than the TV) have lost connection.  Why is this happening and how can I prevent it?

Hello @SSanders1110,

 

Let’s talk about your Wi-Fi.

 

One way to identify an unknown device is to compare the MAC addresses of your connected devices to those showing on your application. Your TV will have its MAC address listed somewhere in the settings.

 

We also recommend changing your Wi-Fi password and network name to something you may be for comfortable and familiar with. You can easily do this by using the smart home manager.

  1. Sign in to Smart Home Manager.
  2. Select My Wi-Fi.
  3. Choose Edit next to the name or password you want to change.
  4. Select X to clear the existing info, then enter a new name or password.
  5. Select Save.
  6. Reconnect your devices with your updated network info.

We hope this helps @cindycolb, please let us know if we can be of any further assistance.

Yes, since the MAC address was foreign to me and did not match any that I have recorded...I removed it and completely reset all passwords on my routers...changed network names and passwords as well.
