Port trunking/Link aggregation on a TPlink AC2300 router

My new NAS comes with dual 2.5gigabit LAN ports (providing a total of 5 gigabit of bandwidth). Its not much use to me because its plugged into a 1gigabit router, attached to 1gigabit internet and a 1 gigabit internal network.

However I noticed a feature on my router called link aggregation. In theory I can plug both LAN ports into the router and get 2gigabits of bandwidth to the NAS. Ok its only mainly useful for multiple connections to the NAS because everything else is sitting on a 1gigabit networking. But you can imagine uploading a lot of data from the NAS and also editing video on my LAN connected laptop.

Link aggreation on TPlink

When looking at the TPlink help page,  it looks pretty straight-forward. However when looking at my router there is no options. No link aggregation options. I checked I have the latest updated firmware and I was thinking of sending it back… till I spoke to a friend and he convinced me to set up port trunking from the NAS side just in case the router has it enabled by default now.

As you can imagine, it worked… I mainly write this as I couldn’t find an answer when I searched for details previously.

Next upgrade for the switches will be from 1gigabits to 2.5gigabits.
