We just bought a Lenovo ThinkPad E570 (which is supposed to have the Intel 8265 for wireless). This laptop was bought in part because it is certified to run Ubuntu and as such to me at least it would make sense for things to work out of the box... but no such luck.
First, I installed Ubuntu 17.10 and after installation realised Wi-Fi was not working. I also tried Ubuntu 16.04 from a USB drive since that is the version of Ubuntu it is certified for, but no luck there either.
The wireless chip is not detected by
lshw (or even
lspci by the looks of it),
ip link does not show a wireless interface, and the
iwlwifi kernel module is not loaded at boot (I can load this myself using
modprobe iwlwifi but this does not make Wi-Fi work). I think it is a combined Wi-Fi/Bluetooth chip, and Bluetooth does appear to work (or at least Bluetooth shows up in Gnome and
modinfo iwlwifi | grep 8265 shows me a file ending in -34 is supposedly loaded but only a file ending in -33 (and some other lower numbers) is present in
/lib/firmware, if that helps).
I have also installed the Linux 4.14.9 kernel in an attempt to get things to work, but this did not resolve the issue either.

I just noticed that the laptop does not have an Intel wireless chip at all, but in fact has a Realtek one... which means that the specs presented on the product page of the shop I bought this laptop at were not accurate... Sigh. Same problem stands, however, just with a crappier wireless chip.
