Hi,
If your Roku Philips TV connects to your phone's hotspot but not your main Wi-Fi network, it suggests that there could be a specific issue with the router's configuration or compatibility with the TV. Here are a few things you can try:
1. Check Router Settings:
2.4 GHz vs. 5 GHz Band: Ensure your TV is connected to the appropriate Wi-Fi band. Some older devices may have issues with the 5 GHz band and work better with 2.4 GHz.
Channel Width: Try changing the Wi-Fi channel or channel width in the router settings, as certain channels may not be compatible with the TV.
Security Settings: Ensure your Wi-Fi uses WPA2 (AES) security. Some devices can have trouble connecting if the router is set to WPA3 or mixed modes.
2. Update Router Firmware: Check if there is a firmware update available for your router and apply it, as updates can improve compatibility with various devices.
3. Change DNS Settings on TV: Go to the Roku TV's network settings and manually set the DNS to a public server like Google’s (8.8.8.8) or Cloudflare’s (1.1.1.1).
4. Disable VPNs or Firewalls: If you have any additional security measures on your router, such as a firewall or VPN, try disabling them temporarily to see if they are blocking the connection.
5. IP Configuration: Check if the TV is obtaining an IP address automatically (via DHCP). You could try setting a static IP address for your TV within the router's configuration.
6. Factory Reset the TV: If all else fails, consider performing a factory reset on the TV itself. Go to Settings > System > Advanced system settings > Factory reset and follow the instructions.
I hope these steps may solve the issue.
