I am new to openwrt and trying to identify what would be cutting my download speed in by almost 40%.

When using openwrt I consistently get speeds of  60-65 Mbit/s but with the stock firmware, other routers, or connected directly to the modem I consistently get speeds of 115 Mbit/s.


All help is appreciated.

Please let me know what other info you would like:
