Now I have a router that is AC1000 R6080, Instead what do you suggest me to use.
This R6080 has an output of 100mbps. Also, Please suggest a 3-4 models.
The R6080 is one of a tiny list of Netgear fairly recent (post 2010), routers that has WAN and LAN ports that max out at 100Mbps (100BASE-Tx). (Confusingly Netgear sometimes labels this "Fast Ethernet".) These are basic, low-end routers. Netgear no longer sells 100BASE-Tx routers. But there may be some left on store shelves.
Anything sold recently offers 1000BASE-Tx. That's 1000 Mbps. Some are even faster.
That means that anything you buy will handle 300 Mbps without breaking out in a sweat.
But you should also check the modem/gateway/ONT or whatever else you are using is also 1000 Mbps or better.
The same proviso applies to anything that you connect to the router. If it is 100BASE-Tx, then it will get 100 Mbps. In that case the Ethernet LAN LED on the router will usually indicate that slower speed. You may see it on various devices that really don't need a Gigabit Internet connection. TVs and Ethernet cameras, for example, happily do their stiff at 100 Mbps.
