I temporarily live in flat where there is only a wired connection. In Linux it works fine (therefore I know problem is not in hardware nor in cable), but in Windows 10 I cannot connect. I tried many things but nothing works:

  • network reset does nothing. After reset and system restart I don't get any message asking to "allow your PC to be discoverable" or any indication that network was really reset
  • Troubleshoot windows tool only says I don't have valid IP configuration", which is clear, since it cannot connect to obtain IP address by DHCP
  • I tried to enable/disable adapter, or uninstall/reinstall driver ... no effect
  • I also tried to enable some runtime services connected to "network discovery" as recommended here https://www.youtube.com/watch?v=UMr5Xd9dyIQ or here https://www.tenforums.com/tutorials/49652-turn-off-network-discovery-windows-10-a.html . This is because my landlord said: You should check your Microsoft settings, that it allows/activates network search automatically; you should activate DHCP. ... but I guess until I obtain an IP address from DHCP this has no effect.

There are two screenshots 1)Ethernet_Settings 2)Troubleshooting

My hardware is "Realtek PCIe GbE family controller" in Lenovo Ideapad Y700 (15") laptop

EDIT: result after trying El8tedN8te's advice to set IPs according to Linux:

  • It seems there is a rogue DHCP server assigning bad address assignments on your network (1. You are receiving an incorrect subnet 2. The address is strange). Set to DHCP and try `ipconfig /release` and `ipconfig /renew` if that doesn't work either please edit what the IP address of the attempted DHCP server is (should be listed under `ipconfig /all`) and also the mac address `arp -a` where it is next to dynamic with that same IP address. – El8dN8 Nov 25 '17 at 14:05
  • I tried this `ipconfig /release` and `ipconfig /renew` (see EDIT 2). My impression is it does not communicate with network servers at all. Maybe the land adapter does not work in windows (although I tired to update drivers) – Prokop Hapala Nov 26 '17 at 16:05
  • How about `ipconfig /all` and `arp -a`? – El8dN8 Nov 26 '17 at 16:08
  • I was a bit uncertain what to do with it ... but If you just want to see output, I attached it under `EDIT 3` – Prokop Hapala Nov 26 '17 at 16:35
  • Disable IPv6 protocol by unchecking it in the ethernet adapter properties. An IPV6 DHCP is assigning you an IPV4 and IPV6 address. Disable it and your problem will likely be solved (I hope) – El8dN8 Nov 26 '17 at 16:48
  • I tried to disable(uncheck) it and not change. I also still have the same IP address. – Prokop Hapala Nov 27 '17 at 17:11
  • I tried to disable(uncheck) IPv6, but no change. I also still have the same IP address – Prokop Hapala Nov 28 '17 at 13:54
  • A bit late... have you tried rebooting the router? – Andrew Morton Dec 21 '18 at 17:41

Run ifconfig in a Linux terminal (since you already have this) and write down these addresses from the output of the command:

  • Default Gateway
  • Subnet Mask - though possibly unneeded
  • Every DNS listed
  • Current IPv4 Address of your machine - though possibly unneeded

Then in Windows, in Ethernet Properties, select IPv4/TCP properties, and set everything to be obtained automatically (though we will set some addresses).

Select the "Advanced..." button and inside the IP Settings tab, select "Add..." underneath "Default Gateways", and enter the Default Gateway address that you obtained from Linux accordingly and keep checked "Automatic Metric"

Inside the DNS tab, select "Add..." underneath "DNS Server Addresses..." and type in accordingly in this order:

  1. The Default Gateway (usually the default gateway also acts as a DNS)
  2. Each DNS list in the order that they were displayed from the ifconfig command in Linux, except the Default Gateway address that had already been entered (if list). If it is not listed, for troubleshooting later you can remove it, as it may not work.

Press Ok, and try out the new settings.

If this does not work disable DHCP by clicking the bullet button "Use the following IP address", and then inside the "Advanced TCP/IP Settings" dialog within the IP Settings tab, click "Add..." and enter the machine IP Address and the Subnet Mask that was used under Linux.

Press Ok, and try out the new settings.

I am noticing that you didn't mention the firewall at all. It's worth checking, since if it has a restrictive ruleset (I don't know the default behavior of Windows Firewall), it will block the DHCP traffic.

  • If this is the issue, the OP should examine and take the approach found in this answer https://superuser.com/a/564711/543035 – El8dN8 Nov 25 '17 at 11:52
  • Hi I tied to disable the firewall or non-private networks ... but no effect. (switch "block incomming connection" was off) – Prokop Hapala Nov 25 '17 at 12:10
