I don?t know why the 2.4G can?t go up to 40MHz. Probably the spectrum is busy. HT40+/- is only used when there is no other activity on the secondary channel. You can use the "no_scan" option in hostapd.conf to override this behaviour and use HT40+/- anyway for testing purposes (but this is doesn't comply with the 802.11n spec and probably even regulation)
