What's the output of equery u wpa_supplicant?
By default, the TKIP USE flag is disabled. |

I tried using only TKIP as a value and I don't remember that I got any error for this. There are many routers supporting only TKIP so that would be an issue which had to be fixed. Anyway, for the configuration posted by me it doesn't matter at all, because "CCMP TKIP" implies that CCMP will be tried first and my router supports CCMP. |
TKIP is the outdated and vulnerable authentication method from WPA. All routers should be set to WPA2 only to avoid this.
wpa_supplicant gets confused when a router is set to mixed WPA/WPA2 even if just CCMP is requested and its tkip USE is disabled (which is the current default in Gentoo).
The solution is to change the router to WPA2 only (recommended if possible) or else enable the tkip USE.
The command emerge -pvO wpa_supplicant can be used to check the current USE values as well. |

| If the router says that it supports TKIP wpa_supplicant will try using TKIP even if the the configuration says not to use it and it will fail when it finds that wpa_supplicant does not support TKIP. Wpa_supplicant must be built with tkip support to connect to a router that says it supports tkip. |
