Slate 7 Pro with 4.8.4 - no where to set MTU?

I have looked everywhere to modify the MTU settings….. nothing, nowhere in the main admin/advanced-settings and Luci. Can someone who has a Slate 7 Pro with 4.8.4, please post a screen shot if you know where it is?? Thanx.

NVM, found it… it’s in the internet settings… have to scroll down.
