1. My router supports gigabit speeds on the Wifi channel and LAN ports. Would this suffice ?

This is where most people get it wrong. Gigabit routers need not necessarly support gigabit WAN ports. You need to look into this specifically. If the WAN port does not support gigabit internet, you would not achieve the required speed even if you have upgraded your internet plan.

2. My internet speed is 300 Mbps. Do I need to have gigabit on the WAN interface

Yes. You need to have. WAN ports can either support 100 Mbps or 1000 Mbps. If your internet speed is between 100 and 1000 Mbps , you need a Wifi router which supports gigabit on the WAN port. if the port is 100 Mbps and the internet speed is gigabit, you would only get a maximum speed of 100 Mbps.

3. How do I know if my router has gigabit wan support ?

You need to check the model number of the router and check the manual or specification of the router.

4.I have upgraded my router. How do I know if my internet speed is gigabit
