My Samsung smart TV was working fine on WiFi but suddenly can't connect anymore. It sees the network but says unable to connect.
Smart TVs are notorious for losing WiFi connections, especially after router changes or TV software updates. Start by going to Settings, General, Network, Network Status on your Samsung TV and try the Network Reset option. This clears stored credentials and lets you start fresh. Enter your WiFi password again carefully — smart TV remotes make it easy to mistype passwords. If that does not work, try a full TV reset of network settings: go to Settings, General, Reset Network Settings, confirm, then set up WiFi again from scratch. Another common fix is to change your router's security protocol. Some older Samsung TVs have trouble with WPA3 — if your router recently updated and switched to WPA3, change it back to WPA2 in your router settings. Also try assigning a static IP address to your TV: in the TV network settings, switch from DHCP to Manual and enter an IP address like 192.168.1.200, subnet 255.255.255.0, gateway matching your router IP, and DNS 8.8.8.8. This prevents IP conflicts that sometimes cause smart TVs to drop connections.
