A picture's worth a thousand words:

arp delete fails

I'm running in an Administrator command prompt and trying to delete an invalid ARP entry. It fails with no error or explanation. Where do I go from here?

  • Have you tried a restart? Disable then re-enable the network card? – DavidPostill Aug 24 '15 at 9:14
  • This problem has actually persisted through a clean re-install of a new operating system. I asked a more specific question a few weeks ago, while I was still on Windows 8.1. Since then I did an in-place upgrade to Windows 10 to get a valid Windows 10 key, then did a clean install of Windows 10 on a blank SSD. – mwolfe02 Aug 24 '15 at 12:50
  • What device is 102? Your current machine? And what device is 200? – DavidPostill Aug 24 '15 at 12:52
  • I think the problem began when I changed out an old Linksys WRT54GS wireless router for a TP-Link TL-WR841N wireless router running DD-WRT. I don't understand what role the router would be playing in wreaking havoc on my local ARP table. Maybe I'm looking at this the wrong way. – mwolfe02 Aug 24 '15 at 12:53
  • Look at your original specific question it appears the issue is the printer not your PC – DavidPostill Aug 24 '15 at 12:54
