I've been using my Western Digital MyNet N750 for at least five years with openwrt and it has run great.
My internet connection has steadily improved over those years and this year my ISP upgraded us to a max of 500Mbps download and I was a little sad that my router with 18.06 only gave me about 170Mbps.
Today I flashed the 19.07rc2 from the ath79 target and saw the checkbox for software flow offloading while reviewing the interface. With software flow offloading I'm now getting the full 500Mbps!
You guys rock, thanks.
