USB Mode 86U

[randomName]

In the helper description it describes the option as disable and enable, but the choices are USB 2.0 and 3.0. Enabling offers the best 2.4GHz wireless performance, however Disabling it offers the best USB 3.0 transmission speed and may effect the 2.4GHz range.

Does one option have an effect on the router CPU performance more than the other? Would completely disabling the 2.4GHz band help? I rarely see any of my devices on the 2.4GHz band as far as what I've observed, and it seems most of my issues that come up with the router are linked to the the 3.0 USB mode. I would like to continue using the 3.0 mode.

Thanks

It should have no effect on the CPU, this option is about USB 3 mode causing RF interference on the 2.4GHz band.

It may have indirect impact. USB 2.0 limits the transfers to ~25MB/s. USB 3.0 allows >50MB/s and locks one CPU core at 100%. Anything else running on it will be more affected.

Wow, the RT-AC86U must have a pretty terrible processor . I didn't bother looking at the CPU loads but I am getting better transfer speeds than that with my old RT-AC68U.

You wish.
RT-AC86U can hit 100MB/s on read.
