Fedora 25: No wifi after update to kernel 4.11.6-201

Wifi was working when I installed fedora 25 live, but when I updated (to kernel 4.11.6-201), it stopped working. My system is an MSI C236A with an MSI Motherboard "Gift" Wi Fi Bluetooth PCI E Adapter Intel 8265NGW. My problem appears to be the iwlwifi card being unable to load firmware... dmesg shows

Direct firmware load for iwlwifi-8265-xx.ucode failed with error -2

where the message repeats for several different integers xx. Curiously, modinfo on iwlwifi indicates that it expects version 28 of the firmware but I've been unable to find it anywhere (it's not part of the firmware RPM and the kernel.org source trees jump from 27 to 31 with nothing in between). I tried adding the 31 version to /usr/lib/firmware and setting the selinux context to match but it refuses to load it. I have not had a chance to try downgrading the kernel packages yet.

I have since tried downgrading kernels to 4.8.6-300 (the base for the release) with no luck, however when installing the kernel packages, I did get an error message: /lib/kdump/kdump-lib.sh: No such file or directory when dracut was running, so perhaps it's trying to put the firmware in an initial ramdisk and failing? But in that case, wouldn't removing and reinserting the module once the system has booted fix things (it does not)?

Also, after booting into kernel 4.8.6, dmesg not only complains that it can't load firmware, but also 'unsupported splx structure`.
