And , I have another query. I'm going to change my ISP which offers Gigabit connection. And I have a router that doesn't support Gigabit bandwidth. Should I go for a gigabit switch or a gigabit router. I only need that bandwidth for my PC. And other devices those will be connected to the router won't need that bandwidth. I found a cheap gigabit switch here (https://ryanscomputers.com/detail/tp-link-tl-sg1005d-5-port-gigabit-switch).
