Computer Hardware Help → Re: [Win7] > Why would a LAN adapter stall?

There are several possible reasons why this problem occurred, however you should start trying to figure it out by looking in the Event Viewer, to see if anything network/dhcp related happened around the time of the loss of network connectivity, then we can make a better assessment of what needs to be done.

I keep forgetting about the Even Viewer, partially because I can't read it.

I believe this was the first error:

Then a few near duplicates of that with slightly different Binary Data, then this:
