Regarding router WAN port speed

[Satish Patro]

I want a router for 1gbps speed. I am planning to purchase TP-Link TL-WR841N (802.11 b/g/n)which has WAN port of 100mbps speed means I can't get speed of more than 100mbps.

1. How much I will get max value practicaly assumming I am using cat 6E cable.
2. WAN port speed how to find? Is it like b/g/n has 100Mbps, & a/c has 1Gbps?
3. Which one to chose for speed among router 802.11 b/g/n router or 802.11 n router? Both have N-300.

If you have a 1gb internet connection I wold not get either of those routers, they are old models.
TP-Link AC1750 is a cheaper model with a gb WAN port.
