To modify you must go to Properties, advanced options of the network adapter of your computer.

Thanks - this sounds to me like you're talking about how to enable Jumbo frame on my network adapter. I've already done that.

I need to know if my router supports Jumbo frames. I cannot find any settings with my router config where I can change the (LAN) MTU / jumbo frame size. The router has Gigabit switch ports, I'm using Cat5e, my network adapter and NAS are gigabit, with Jumbo frames enabled.

My PC (with gigabit NIC) connects to port 1 of my router. My NAS connects to port 2 of my router.

I would like to use 9K Jumbo Frames to transfer data between them.
