- KERNEL:
$ curl -s https://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.14.6 | grep iwlwifi

So pick up kernel-3.14.6-200.fc20.x86_64.rpm
http://koji.fedoraproject.org/koji/buildinfo?buildID=531773

You can also try with kernel-core-3.15.0-1.fc21.x86_64.rpm
http://alt.fedoraproject.org/pub/alt/rawhide-kernel-nodebug/x86_64/


- FIRMWARE:
$ modinfo -F firmware iwlwifi

# yum --enablerepo updates-testing install iwl6000g2b-firmware

$ rpm -qf /usr/lib/firmware/iwlwifi-6000g2b-6.ucode
iwl6000g2b-firmware-17.168.5.2-38.fc20.noarch

According to
http://wireless.kernel.org/en/users/Drivers/iwlwifi#Firmware
Intel® Centrino® Advanced-N 6235 goes with iwlwifi-6000g2b-ucode-18.168.6.1.tgz
i.e. iwlwifi-6000g2b-6.ucode
also stated within firmware itself:
https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-6000g2b-6.ucode
"IWL.6000g2b.fw.v18.168.6.1.build.0"

However in Fedora it is packaged as "17" i.e. iwl6000g2b-firmware-17.168.5.2-38.fc20.noarch

However checksums are equal:
   $ sha1sum /usr/lib/firmware/iwlwifi-6000g2b-6.ucode \
   > /tmp/iwlwifi-6000g2b-ucode-18.168.6.1/iwlwifi-6000g2b-6.ucode
   0c5dbfed5f50ef39b56827651f572bea25bfc27e  /usr/lib/firmware/iwlwifi-6000g2b-6.ucode
   0c5dbfed5f50ef39b56827651f572bea25bfc27e  /tmp/iwlwifi-6000g2b-ucode-18.168.6.1/iwlwifi-6000g2b-6.ucode
So you are good to go with "17".


Josh, do these two firmwares should be in their own packages as "18"?

Intel® Centrino® Advanced-N 6235 - iwlwifi-6000g2b-ucode-18.168.6.1
i.e. iwlwifi-6000g2b-6.ucode - "IWL.6000g2b fw v18.168.6.1 build 0"
in iwl6000g2b-firmware-18.168.6.1-1.f$releasever.noarch.rpm

and

Intel® Centrino® Advanced-N 6205 - iwlwifi-6000g2a-ucode-18.168.6.1
i.e. iwlwifi-6000g2a-6.ucode - "IWL.6000g2a fw v18.168.6.1 build 0"
in iwl6000g2a-firmware-18.168.6.1-1.f$releasever.noarch.rpm
