No, jumbo frames is an ethernet standard, not a wireless ethernet standard. Enabling Jumbo Frame without proper support from your network infrastructure or devices can potentially lead to connectivity issues. The main idea of enabling jumbo frames is that when full sized frames are used with jumbos enabled (today normally 9000 bytes or so, but up to 12000 bytes or so can exist depending on vendor and interface) you have (with 9000 as MTU) 1/6'th the amount of interrupts needed to maintain the same amount of data on the wire. There's only one way to know for sure, give it a try. Historically, Ethernet has a maximum frame size of 1500 bytes. It is out of ethernet specific and has ethernet switch/hub compatibility. Every device on the same VLAN is either using standard 1500 byte fames or jumbo frames. Back when NICs passed all this stuff to the CPU, it was worth it more. I think you're' saving a lot of interrupts and packet header overhead. Worse, sometimes larger packets will actually get dropped by routers that don't support jumbo frames so I think you'd actually find things are worse if you try sending jumbo frames to the internet.
