The download link on that page just goes to a doc about installing firmware updates.
As noted several months ago here, I and many readers had problems with firmware 7.4.1 (many reverting back to previous firmware), hopefully this update improves things. If you update to firmware 7.4.2, let me know if it helps (or not).
I've just updated my AE N (simul dual-band) base to 7.4.2, but too early to tell if it's improved over 7.4.1.

The download link goes to a page requiring a Log-in, but if you have FCP 6.0x installed, it will appear in Software Update. (And you can use the "Download" Software Update menu option if you like to use d/l updaters and save a copy of them as I do.)
