Wolfaslov Posted February 16, 2021 Share Posted February 16, 2021 I bought two identical TV's (LG 55Nano90). There are free C4 drivers specific to this model (which I added to the project). Both TV's are hardwired to the internet and, obviously, have different MAC addresses. I have the same settings on the TV's (in the LG C4 section of the TV menus) and in composer for BOTH TVs. One works flawlessly and the other is hit and miss (mostly miss). If I have that TV on Wi-Fi only, it'll work 50% of the time......conversely, if I have it on Wired only, it works 0% of the time. In the properties of the TV on C4, it often says the TV is offline, and once that happens, there's zero IP control. I've followed the driver's included instructions to a T, to no avail. Has anyone ever experienced anything like this, or have any suggestions? I know one solution is to use IR blasters only....but that's a final fallback plan. os3.2.1 Thanks kindly.

lippavisual Posted February 16, 2021 Share Posted February 16, 2021 Similar situation many of times before. Check your ethernet connection from router/switch, all the way to the device. Quote Link to comment Share on other sites More sharing options...
Wolfaslov Posted February 16, 2021 Author Share Posted February 16, 2021 fair comment. If I use the LG remote, the TV and all the Smart TV functions work flawlessly (including 4K streaming). I don't think that's the issue, but I could be wrong..... Quote Link to comment Share on other sites More sharing options...
msgreenf Posted February 16, 2021 Share Posted February 16, 2021 are you miixing the mac addresses from WIfi and wired in the other config? Quote Link to comment Share on other sites More sharing options...
Wolfaslov Posted February 16, 2021 Author Share Posted February 16, 2021 I was very careful to look at that (MAC Addresses) to make sure that I was not...... Quote Link to comment Share on other sites More sharing options...
Wolfaslov Posted February 16, 2021 Author Share Posted February 16, 2021 well, @lippavisual was on the right track and it got me thinking..... My current network flow to the TV is from Cable modem to large, rack mounted, 24 port gigabit switch to an old DLink gigabit router [(DHCP turned off) therefore converted to a network switch] and finally to the TV. Needed the DLink router/switch as there's only one LAN port in the room and have a computer and this LG TV in the same room that need LAN. Soooo....bypassed the old DLink router/switch and hooked up directly to the TV. Now the TV works flawlessly. I don't understand why this was the issue (as all the SmartTV content worked perfectly the way it was set up)....but more importantly, not sure how to proceed.....Maybe just buy a new dedicated gigabit switch for that room!?

msgreenf Posted February 16, 2021 Share Posted February 16, 2021 You were double nating probably. Buy a switch. Wolfaslov 1 Quote Link to comment Share on other sites More sharing options...
lippavisual Posted February 17, 2021 Share Posted February 17, 2021 Routers, especially consumer grade, have their own firewalls and LAN. Even though DHCP was off, that LG was on a different LAN than your main network. eggzlot, Wolfaslov and msgreenf 3 Quote Link to comment Share on other sites More sharing options...
Wolfaslov Posted February 19, 2021 Author Share Posted February 19, 2021 just a final follow up on this....added a dedicated network switch and boom, everything works perfectly.....lesson learned here. Thanks kindly Quote Link to comment Share on other sites More sharing options...
