A printer, a NAS or a port forward needs an address that does not move. Pick one outside the DHCP pool, set it per adapter, and keep the path back to DHCP open.
Note the DHCP values, pick an address **outside the router's DHCP pool**, then set it with **New-NetIPAddress** and **Set-DnsClientServerAddress**. One command pair puts the adapter back on DHCP.
**Get-NetIPConfiguration** shows address, prefix, gateway and DNS in one block. Save that output before changing anything — it is the fastest way back when a value is wrong.
Get-NetIPConfiguration -InterfaceAlias 'Ethernet' -Detailed
Get-DnsClientServerAddress -InterfaceAlias 'Ethernet' -AddressFamily IPv4The router hands out roughly .100 to .200 on most home networks. Take something below that, and confirm nothing answers on it before you claim it.
ping -n 2 192.168.1.50
arp -a | findstr 192.168.1.50An existing DHCP lease and a static address on the same interface produce a conflict, so turn DHCP off first. **PrefixLength 24** equals the 255.255.255.0 you know from the dialog.
Set-NetIPInterface -InterfaceAlias 'Ethernet' -Dhcp Disabled
New-NetIPAddress -InterfaceAlias 'Ethernet' -IPAddress 192.168.1.50 -PrefixLength 24 -DefaultGateway 192.168.1.1A static address without static DNS inherits nothing and falls back to nothing. Two resolvers keep name resolution alive when one is down.
Set-DnsClientServerAddress -InterfaceAlias 'Ethernet' -ServerAddresses 1.1.1.1,9.9.9.9
Resolve-DnsName example.com -Server 1.1.1.1 | Select-Object -First 3Gateway reachable, DNS answering and a real TCP connection are three different tests. Run all three so a DNS failure does not look like a broken network.
Get-NetIPConfiguration -InterfaceAlias 'Ethernet'
Test-NetConnection 192.168.1.1 -InformationLevel Quiet
Test-NetConnection 1.1.1.1 -Port 443 -InformationLevel QuietTwo commands undo the change completely. Run them before you move the machine to another network, otherwise the old subnet follows you.
Set-NetIPInterface -InterfaceAlias 'Ethernet' -Dhcp Enabled
Remove-NetIPAddress -InterfaceAlias 'Ethernet' -IPAddress 192.168.1.50 -Confirm:$false
Set-DnsClientServerAddress -InterfaceAlias 'Ethernet' -ResetServerAddresses
ipconfig /renewAnother device already holds it, usually a printer with a fixed address nobody documented. Pick a different one and confirm with ping before you set it.
That is DNS. Compare Set-DnsClientServerAddress output with the values you wrote down, and remember VPN adapters can override the per-adapter list.
Interface aliases change with language and with every reinstall. Use Get-NetAdapter to read the exact alias or address the adapter by InterfaceIndex.
The static address still points at the old subnet. Set the adapter back to DHCP, renew, and only then configure a new static address.
A reservation is cleaner: the router keeps the bookkeeping and you cannot create a conflict. Use a static address when the router has no reservation feature or the device must work without it.
Yes. It is stored in the network profile and stays until you change the adapter or reset the network stack.
Set the interface back to DHCP with Set-NetIPInterface -Dhcp Enabled, remove the static address with Remove-NetIPAddress, reset DNS with -ResetServerAddresses and run ipconfig /renew.
