I am currently running the latest B1300 firmware (v 3.212) and see huge performance problems with routing internet traffic.
I connect to an internet bridge (provided by a Ubiquiti Bullet M2) via ethernet. If I connect my laptop to the bridge directly, I am able to get 20 Mbps up and down speeds; however, as soon as I connect the to the bridge through the B1300 (via WAN port cable) in Router Mode, the clients connected to the B1300 are only able to receive around 5Mbps download speed. I have tried both connecting clients to the router via ethernet cable and 5Ghz Wifi.
Why am I losing 15Mbps of throughput going through the B1300 router? This performance loss is w/o VPN enabled.
