Very strange issue:
When connecting the CAT cable to LAN port on my ProBook it gets a link (on a router port which I use several months already) but after trying to identify the network for a while it says "no identified network" and switches to WiFi.
This is my office network which it worked before for years, and yes... I tried ALL solutions available I found in the internet (driver update, re-installing, Windows troubleshooters, even a fallback to an earlier Windows state).
The same behavior has been identified at two locations, two different networks...
Strange thing is that if the LAN port/chip would be broken, I assume that it won't work at all, but as it gets a link and is available in the device manager (there everything is OK) I am really confused and don't know where to go on.
Would be great to get any hint I can build on.
Thanks a lot for your support!

Did the firmware update:
- installed all the recommended updates
- did a network reset, everything went fine
- after reboot: problem still exists. When I turn off WiFi, not switching to LAN as of unidentified network.
When deactivating the adapter and activating it again it takes about a minute until it shows unidentified network.

did the Realtek driver installation
chose repair of drivers
tool was installing/updating all drivers
shortly after login it was displaying the LAN network symbol in the right corner... but as soon as I was realizing it and thinking the issue has been solved, it switched to WiFi again 😞
WiFi network is being identified in few seconds with success, LAN is not

Check the following:
- Is DHCP or static IP used ?
- Check or replace the LAN cable
- Check the LAN socket (Notebook and Network Switch)
- Check if you can get a connection with a USB-to-LAN adapter (or another computer) using the same LAN cable

- DHCP is used, tried also to set static IP, no change
- as said, same behavior on different locations/network, anyway, changed the cable, same same... definitely no cable issue
- see above, tried it on two different sites with different networks, exactly the same (both have worked before without any problem)
- hmmm, no adapter available, but I will order one...
HP network assistant also tells me that everything is fine.
So I really think it is not a hardware issue, as also device manager tells that everything is OK, but some kind of Windows/HP bug. It really started from one day to the other, without doing critical things on the setup (besides the normal Windows update procedures).
BTW: Thanks a lot for your support, I really appreciate!
