Cisco/LinkSys WRT310N v1 (at least I think it's V1 because there is no "V" visible on the label).
Looking at the "build-types" page I see that, for v1, I want MIPSR1 K2.4.
The two files I've downloaded so far are tomato-ND-1.28.8754-Std and tomato-NDUSB-1.28.8754-Std.
But neither one tells me if it is the magical "MIPSR1 K2.4".
What am I missing?
