I recently switch to Fiber from ATT and got the BGW210-700. speed tested it and it fact is 1000( 968Mbps). However, I still want to use my NightHawk x10 as my main router that control the DHCP pool, BUT! it's only getting less than 500 Mbps.
The modem (BGW210-700) is on Ip Passthrough mode with DHCPS fixed to my router and all the firewall settings off, and both modem and router are using Cat 6 cables, and I'm still receiving less than 500mbps ( I did a speed test within the router and it saying it's only receiving less than 500mbps ).
