Move your PC to LAN3 or use another cable (CAT 5E/6) to connect to C80 and see if that helps.

You may consider upgrading the C80 FW if the former doesn't help and try again.

Thanks, it worked:

Why is it working like that ? What caps Lan1 or Lan2 to be at full 1gbps speed :?

For LAN1 could be a loose RJ45 plug contact. For LAN2 could be that your TV is only 100mbps capable.

You can check LAN2 as well by connecting your PC there and the TV in LAN3.

In general a good quality, factory made ethernet cables are preferable for connection stability.
