LG TV strange connection issue

[Frederik Kordiak]

Hi all, so I have 2 LG OLED TVs at home and I am connecting them to 5GHZ Wi-Fi, no problem until yesterday. Suddenly, I am not able to use the apps (Netflix, IPTV, Disney etc.) and both TVs are showing connection issues. The same Wi-Fi works on my PC and mobile though. So I tried connecting using a different Wi-Fi with my hotspot and both TVs worked again with no problems. I tried restarting my router many times and my provider said there is no issue on their end, but I am not able to use the home Wi-Fi anymore. 

Have you seen this before? Is it possible that my provider blocked my LGTVs from accessing their network?

Thanks

I doubt the provider would do this.  Providers need you as a customer as much as you need the provider. Have you restarted your modem? Have you reset your modem to factory settings? Restart the modem first by unplugging the modem for about 15 seconds but up to a minute if you would like.

I tried restarting the modem many times, also did the factory reset and nothing helped, unfortunately.

Try to change your wifi security settings to WPA2/WPA3 with AES encryption. Also try to change the wifi channel.

I tried both and when I changed from WPA2 to WPA3, it worked for about 2 minutes and then again, the same problem

Hi @Frederik Kordiak

Has your ISP done a remote upgrade on the modem recently?
