Out of the box this router is average with average wifi signal. I use TPlink longer antennas, also I use the David Openwrt firmware. It's great for my NBN HFC paired with a Cisco SPA112 for VOIP.

I have had numerous WRT routers, and this one is as good as any of them. You can flash it with a custom Linux based firmware and practically use it as a computer. I am running a custom firewall, torrent, and a VPN server directly on the router. Can't recommend it more...

I have been using this router for the past few years and I stand by it. The industrial build only serves to match the workload this is able to take on with minimal fuss. I rarely have to restart it and it is constantly providing excellent speeds to my entire house (4 bedroom)

Bought the router because my NetComm wireless router couldn't reach the garage which is separated from the house. With WRT1900ACS, I can get powerful signal even though the garage is full of metal panels and shelves and can play Netflix movies in HD with my Apple TV 4.

I have also installed Untangle Web filter firmware and filter all the traffic to prevent my little kids accidentally access inappropriate content. Router works without any issue with the custom image. Best router ever purchased.
