	Ah, understood, I guess continuous testing works well with this approach :)

	Ah, yes, I was looking for radio buttons initially came up blank, then failed to get LUCI's :depends mechanism work properly and just resorted to exposing both checkboxes. Far from ideal, I guess in the next iteration I will just have a drop down bow with "none", "htb", "stab" then it will be unambiguous.

	More hardware, more pain? I wonder, have you found a successor to the WNDR3[7|8]00 yet?

	Okay, not that it is conclusive, but 3.10.1-1did not crash on me once.

	So are Felix changes already in 3.10.6? If so I will ahead and try to sysupgrade it (I always can fall back to TFTP even if it is a bit inconvenient due to positioning the router above my reach :) )
