Recantly I am Facing a Problem.Some Days Ago, I took a Fiber Line From my ISP Only For My House. They Provided me A Gigabite Onu(not TP-Link) and a pppoe account.
I have 3 300mbps routers in my house. So I made one base router and others are sub. But the Problem is if I download random files from Sub 2 with full speed the main router will not able to transfer any data as the limit is 300.

So Why Tp-Link dont make this type of switch or something like this which is able to authenticate with pppoe and thn Work was LAN. 

Yes I know there are some Gigabit router. But those price is little bit high for myself. And I dont want the Feature of Wireless System.
DO Tp-link Have any plan to make a device something like this ?!
I didnt found any device in market or something like that
I guess This kit will help a lot of person.

Thanks
