gigabit router slows down on long range ethernet cable

I have set up a basic FTTH in my home I have:

  • 150 Mbps Connection
  • Mi Route 4A Gigabit
  • TP-Link Gigabit Switch (5 Ports)
  • Tenda Cat6 Cable

My Router sits 131 Feet away from my laptop if I connect with or without a switch to my laptop with a patch cable like 1 foot I get the full bandwidth of around 150 Mbps but when I connect to my patch which is 131 feet away I get 100 Mbps, I tried clipping new connectors but no fun, so I want to ask do I need to buy a new router which supports it? I’m not sure which router will help in that case. Secondly, I followed the T-568B method to clip the connectors.

At this point it’s clear to me that either ethernet does not support this kind of long-range for a gigabit port rather it slows down to 100 Mbps or my router does not support or does not have the energy to travel the signal at that speed.

Please guide.

Thanks
