I use Hyperoptic internet 150 Mbps. On my computer and phone, signal is strong but on my LG OLED 65 tv connection speed was low. Ethernet increased it to 20mbps then I moved the router to the living room closer to my TV (without LAN Cable connection) and suddenly internet connection speed went up between 70mbps to 120mbps on 5ghz.
For those with LG OLED tv, I recommend you bring the router towards the TV, use 5ghz because it's stronger than Ethernet or LAN/Cable connection .
Note this is only applicable to LG OLED tv.
I have this tv-
I'm using it connected to wifi. Everytime I turn it on the internet is extremely slow unless I disconnect from the wifi network, and then reconnect. Any ideas as to why this might be?
