Dude - only device with packet loss on my network

I am running a Dude server monitoring my network on an x86 box. I believe this issue arose Friday night, about 24 hours ago. I’m certain it wasn’t an issue months ago.

I can ping anything and it gets major packet loss. Even itself! If I log in to Winbox I do not see this packet loss. I can ping 10.10.10.10 (itself) and see 80% loss, which is consistent with any other device on the network).

It was ROS 3.22 and Dude 3.5.

I upgraded to Dude 3.6 - no change.

I upgraded to ROS 3.30 - no change.

I logged into a WinXP machine at the office that is on the same switch as the server and it is seeing the exact same results as my home WinXP desktop. This ruled out issues between my home client and the server (because you will see no replies to pings if you can’t get a timely response from the Dude server or you lose connectivity to it).

I am posting this here before emailing support in hopes the community has more information on this. I can upgrade to 4.0b1 if need be, but I prefer working with stable releases.
