Netgear Nighthawk M1 MR1100 ARP pollution and Devolo Magic 2 powerline network
I've been using a Devolo Magic 2 powerline network in the home for some time now and it's been known-good up until recently when I've added a MR1100 back into the network onto the powerline network i...
Recording a Windows 10 fix in case this helps anyone else.
- Right-click Start menu and select "Windows PowerShell (Admin)", approve modifications to system.
- Run the command "arp -a" to diagnose the issue of the default gateway having an incorrect MAC address related to the MR1100 instead of the correct MAC address.
- Run the command "Get-NetAdapter" and make a note of the ifIndex.
- Run the command "New-NetNeighbor -InterfaceIndex <ifIndex> -IPAddress '<gateway_IP>' -LinkLayerAddress '<MAC_noseparators>' "
Single quotes are part of the command. Example of MAC_noseparators is '3cecefXXYY5f'. Remove-NetNeighbors -InterfaceIndex '<ifIndex>' -IPAddress '<gateway_IP>' # to reverse this fix.
Now I need a solution for Windows 10 S.
Quick summary that the same workaround also works when downloading PowerShell on Windows 10 S from the Microsoft Store which wouldn't be expected to run (e.g. WinDbg Preview doesn't, as expected) so it might be disabled at some point.
A longer walkthrough seems not to have posted.
