I have upgraded my machine to windows 10 and everything is working fine except Ethernet port. The driver’s are latest and up to date. Still wired Ethernet doesn’t get detected or connected.

with the network cable attached to the z400 do you get a link light on the nic port?
does the router (if you use one) show a connection?
is the nic cable wired correct and not a crossover type?
does device manager show a working nic or a yellow or red icon?
was the network port working before the upgrade?

Yes, I recall this. I'm surprised HP/MS have not got this fixed yet. Check what version of W10 Pro 64 Broadcom 64-bit driver MS put on your box and let us know if you can.
Turns out some older network adapter versions work fine with W10Pro64 and for some reason the default driver MS has available does not. I'll get you an update in a followup post here on what we've been using or years now on our Z400 v2 in our home library. Yes, clean installs of W10 on ZX00 boxes here also has broken internet access. Luckily these other drivers that work.
Below are my old notes related to a forum post here regarding the HP Broadcom W10 internet access loss due to auto-default to a newer Broadcom driver MS provided that does work with W7 fine, but does not work with W10. In contrast, 184.108.40.206 does work well with both W7Pro64 and W10Pro64:
The post: "I have same issue with my Dell Latitude D620 after I upgraded to Windows 10 Pro 32 bit version. Broadcom NetXtreme 57xx Gigabit Controller worked (17.0.x) fine with W7 before upgrade. I finally fixed the issue by using an older version of the driver... in my case it was Broadcom NetXtreme 57xx Gigabit Controller version 220.127.116.11 [9/12/1013]. You will find this driver available in the windows driver list automatically available to you from within Device Manager. I installed it from Device Manager... choose Browser my computer for driver- Let me pick from a list of device drivers on my computer. You will see this driver in the list. It worked for me ! Hope this helps."
SDH added notes: The 18.104.22.168 was the one that was auto-installed on one of my Z400 v2 builds of loading W10Pro64, and clones of that build have worked correctly from the very beginning. I have no idea why the install defaulted to that good driver in that case. I also have used the above Device Manager method to navigate to the 22.214.171.124 driver available as an alternative driver cached on the SSD in a more recent W7 upgrade to W10 activation method. Internet access on W10 boot was immediately restored by doing that update to 126.96.36.199. The "yellow bang" flag in Device Manager resolved upon doing the driver change and a restart.
Of interest, on these W10 activation installs there seem to be 3 provided drivers from MS, and only the 188.8.131.52 of the three worked. The 184.108.40.206 driver set works fine for W7, but not for W10 on these workstations. The third set also did not work.

Attached is a pic of the network adapter driver we're using now for our home Z400 v2 W10Pro64 21H1 build, and this 220.127.116.11 driver released 4/6/18 has worked fine with W10Pro64 for years now.

i do not get any link light on the nic port and also on the router side.
The cable used is straight cable and the device manager shows a working nic.
It was working perfectly before i updated from Windows 7 to Windows 10.
not sure why the ethernet port is getting detected.
