LG TV refuses to forget WiFi network
I'm not sure if this has come up in all the recent LG spyware/privacy discussion, but I figured I'd share my experience.
I recently created an isolated WiFi network in UniFi specifically for my LG TV, to keep it separated from the rest of my devices. I connected the TV to the new network and everything worked fine.
The next day, I noticed the TV had automatically reconnected to my old WiFi network.
So I went into the LG network settings, told it to forget the old network, and connected it back to the isolated "LG jail" network.
The following morning, the old network had somehow reappeared in its saved networks, and the TV had connected to it again.
At that point, I changed the password on my old WiFi network so the TV could no longer connect to it. That worked and forced the TV onto the isolated network.
Then I tried something else: I manually added the old WiFi network on the TV but intentionally entered the wrong password, hoping that would overwrite whatever credentials the TV had previously saved.
Afterward, I changed my main WiFi password back to its original password, since several other devices depend on it.
The next day, the LG TV had connected to the old network again.
So unless I'm missing something, once this TV has successfully connected to a WiFi network, it appears to retain those credentials somewhere even after you:
- Tell it to forget the network
- Reconnect it to another preferred network
- Attempt to overwrite the saved credentials with an incorrect password
It still eventually goes back and tries credentials that worked in the past.
Maybe there's an innocent explanation for this, but it's pretty concerning behavior for a device that already has a reputation for aggressive data collection.
Bug, undocumented credential retention, or an intentional "feature" LG would rather not discuss? I know my vote...
(in the end I blocked the LG TV's MAC address on my main WiFi network)
