BGW-210 IP Passthrough speed slowdown
I have successfully configured my new BGW-210 to use the IP passthrough feature so I can use my own router (ASUS RT-AC1750). The functionality is there no problem (I can access my internal network and the internet just fine), but the speeds are slowing down from over 900mbps to around 500mpbs. I've verified that the firewall and the wifi of the modem are both turned off. I've also verified my LAN speeds are not bottlenecked by my router (getting around 900mbps no problem from one computer to another). Using the same computer, wired, through the modem is fine, but simply switching the cable to go through my router slows it down by 400mbps.
Any successes with maintaining gbps speeds through the IP Passthrough feature?
