I’m having a weird issue with my new Asus router to replace an old Netgear AX nighthawk and for some reason any network data transfer to my DAS and network drives caps out at 40MB/s no matter the drive ifit be HDD or SSD all cabling CAT6, gigabit switches, PCs report the link speed is 1000Mb, my gigabit fiber Internet speed tests normal 900+Mbps wireless and wired but I cannot figure out why I’m capped at 40MB/s transferring to/from my network drives with this new router.

My old Netgear AX router would transfer 100-120MB/s. Is there any settings I need to change?
