Ah some of these would be nice to have incorporated into Tomato.

But Tomato doesn’t even support RT-AC87U. Which is a shame. And the problem with its QoS is that it doesn’t work anymore. In the past it used to be the most powerful one. I had it on my old Linksys and I could setup QoS in such a way that I could do anything and it wouldn’t interfere with other tasks. Later I bought a Netgear Nighthawk, I think it was X3. Totally didn’t work as it did before. Which is a shame. But ASUS’s QoS does work and it works really well at classifying data streams. It’s super smooth as well. I can download and play games and it all just works perfectly.

I will take note because QoS was very important to me a few years back. I run the latest Tomato Shibby build on an R7000 currently. Very tempted to try something new.

This firmware wrecks havoc on an AC3200. Random connects/disconnects, big problems with the 2.4GHz band. These are widespread problems.
