When I change the MTU to 2000 in the mybooklive I am able to ping the mybooklive with packets as large as 1972, which indicates that JF are working for it. If I telnet into the router and do 'ifconfig' it shows 1500 for the MTU for br0, eth0, and eth1.Īm I incorrect in assuming that Jumbo Frames should change the MTU, or am I confusing something, or does JF not work for this router? When changing both device manager and the router to 4K, I get the same result. The numbers directly after the mtu is the value.

So, use it to check the MTU size allowed by your network interfaces. Everything here is going to be handled with the ip command. It’s probably 1500 bytes, since that’s the default, but it’s good to make sure. When turning on JF 2k, 1504 is still the largest size I can use. Now that your network supports jumbo frames, check what your computer is set to. advanced features such as Quality of Service controls, iTunes server, jumbo frames or VPN server. When I ping the router wirelessly, 1472 is the largest size I can use. The Linksys EA6350 is a very good budget Wi-Fi router.

Another strange thing, without enabling JF in the router, when I ping the router with the command 'ping 192.168.1.1 -f -l ' the largest size I can use is 1504 bytes, which indicates to me that when not enabling JF in the router, it is still using a larger MTU than 1500.

One strange thing I have noticed is that when I set Jumbo Frame size to 2K in device manager, the actual setting in registry is 2034.

I recently purchased a Western Digital Mybook live. I have a E2000 running latest toastman firmware, and I have a Realtek nic in my laptop that supports various Jumbo Frame sizes, starting at 2000. I've been reading into Jumbo Frames and reading a bit about them, but I'm a little uncertain if things are working correctly.
