Just logged onto the router in a building where I do the wifi and there is a Fn-Link device which appears to be associated with a LGwebOSTV which a new occupant apparently brought in recently. Looks like the TV has two wifi devices, could be a bit like "belt and suspenders". Fn-Link seems to be known not just for their WiFi interfaces, but WiFi-IOT "modules" having quite capable processors also, which they seem to be fairly accomplished at. Interestingly, AI screeds that Fn-Link is heavily associated with "mesh." The router usually does a pretty good job of identifying what kind of device, from phones, PCs, tablets, Macs, switches, extenders, etc. The TV is identified by name as above and automatically showed the proper TV icon, and it would have to have been given the proper user wifi password when set up or it wouldn't be on the router to begin with. Main TV wifi is directly on the router's 5G frequencies. The Fn-Link named device is always using the preceding IP address by DHCP, but it is logged into a separate 2G extender also within range which does use the same password. The main router autoassigns to the Fn-Link the kind of icon you get from an extender or wifi access point itself. I'm getting the idea that the Fn-Link PCB gets the wifi password from the TV setup routine then takes action on it's own from there. Will be changing the password on the extender and see if the Fn-Link moves to the main 5G channel. More alarming was the way my buddy's MacBook Pro had apparently logged into the Fn-Link device and was sharing the same local IP address, could very well have been MITM'd until I blocked the Fn-Link device and the MacBook went directly back on the main 5G router. Re-allowing the Fn-Link device has not seemed to be involved with the MacBook after that. Take a look at the "Fn-Link Product Manual.pdf" on this page for a general line card: https://www.fn-link.com/download-p2.html https://www.fn-link.com/download-p2.html And something like the "AIot module" here: https://www.fn-link.com/V200Z-R-AIoT-Module-pd41426492.html https://www.fn-link.com/V200Z-R-AIoT-Module-pd41426492.html To get the minimal rundown on explicit capabilities. Of course they also appear to be very advanced when it comes to the less-common PLC-IOT modules which are used for industrial control, so it's not like they're completely driven by the relatively huge consumer market, more like the mission to collect data and execute control where it hasn't already been addressed, wherever it may turn up. Naturally Fn_Link also makes modules that support GSM and CDMA also
