thinkpad carbon 5thgen + thunderbolt 3 dock

Hi list.

I have a thinkpad carbon 5th gen with ThinkPad Thunderbolt 3 Dock. The
notebook doesn't work well with dock station, and I'm looking forward
for some suggestions. Here it goes:


Wireless iwm doesn't support even N and AC is not supported at all. The
wifi is much slower then on my old machines. I'm going to replace the
wifi card in mean time, any suggestions which one to buy?

Graphics works perfectly. NVMe SSD with OPAL wouldn't allow machine to
resume from sleep, sometimes it does after big timeout and writing
errors to console, sometime it just reboots.

Thinkpad Thunderbolt Dock Station, here is where things get
interesting. If I boot machine connected to dock station, peripheral
devices would work, external monitor, keyboard, and mouse. There's no
other way I know to make it work. Once detached - it wouldn't see
devices again. Booting and THEN attaching - the same, machine wouldn't
see devices.

Here is the device being seen (a lot of pcib*):
pcib5_at_pci0:6:0:0:       class=0x060400 card=0x11112222 chip=0x15d38086
rev=0x02 hdr=0x01
    vendor     = 'Intel Corporation'
    device     = 'JHL6540 Thunderbolt 3 Bridge (C step) [Alpine Ridge
4C 2016]'
    class      = bridge
    subclass   = PCI-PCI


For me the main concern is Thunderbolt thought, docking station is
amazing thing. Any ideas and thought how to make it work would be
highly appreciated.
