My goal is to upgrade from stock firmware to Merlin firmware. I want to do this to improve Open VPN with my Tor-Guard VPN service. Using stock firmware having the VPN on the router my speeds are really bogged down. 7 to 12mps. This is the only thing which keeps me from running VPN on router. I heard that Merlin firmware would improve this. I have default 200mps download speed. Once I upgrade to Merlin firmware are there any tutorials for configuring my router once this is done?
