Seems like carrying eggs in omelets would be more reliable. But I'd still avoid having a single-omelet-of-failure.
When I got home last night, I discovered my primary Windows PC wasn't able to find the network. My primary Macintosh machine also failed to find things outside of the house. Tracing up the waterfall of digital goodness, I discovered that my router/access point/firewall had no lights on, and nothing I could do with the various cables sprouting out of it would do anything.
The good news is that I was able to roll in to Staples this morning before 9am, return home, plug it in and attempt to set the device up using their multimedia wizard configuration tool. That didn't work out at all, so I ended up plugging a laptop directly into the device and set up such arcane trivia as netmask, gateway, and port forwarding details.
And here I am at work, and I'm pretty much blocked from getting work done here. What a weird contrast, having been "productive" in the sense of bringing my home network back up again - a lot of work to return to the level of functionality that it was at 16 hours ago.
But the note to myself, as hinted by the title, is to jot down the addresses and port assignments in some non-electronic format, so that I might be able to refer to it when I need to again.
