Does the RT-N16 support Jumbo Frames with the latest tomato firmware?
I'm trying to get it to work, but it doesn't seem to be working.
It should - there's an option in the admin. Post your firmware version and maybe try the one Toastman posted (it's the latest one from the repo). I recall some posts/commits about this feature but I haven't tried it myself.
Note that if I'm not mistaken, Jumbo frames work only if all participants on that network use them - otherwise it downgrades to the standard packages (just like a gigabit switch which downgrades to 10 or 100 when a client with this speed connects through).
Recent Asus firmwares apparently
Support Jumbo frame of LAN to LAN
trying that would help identify if the problem is with Tomato
Latest Asus beta for Russia even has
6. External Optware packages support
