I am after a recommendation.

I recently had a 900MB FTTP installed which is great.

I have a Draytek Vigor 2680AC router which is all set up and working. This is plumbed into a switch which feeds an Open Mesh system which has 3 access points.

I knew the Vigor has a 300MB firewall throughput limitation on it and the wireless system isn't being fed anything above 300 at the moment and I would need to replace the Vigor or put a new firewall unit in place and disable to Virgor firewall.

I am after some advice - I am not interested in the wireless aspect of things for the router / firewall but want a recommendation of what I should buy to get the best out of the speed I have through my wireless. The Open Mesh system is more than capable of dealing with it - just need to feed it and remove the firewall throughout limitation.
