In the grand total of 2 (count 'em, 2) events we've run with the new hardware system, we've had problems with our secondary devices going offline intermittently, leaving the primary computer as our only method of controlling the event.
In an even worse side effect, we are then besieged by 50 drivers all wondering what their times were because they can't reach results.com. You can imagine the stress under the tent. My wife is a saint, I'm just saying.
After the first event, we thought it was caused by power fluctuations from the little generator we use. So for the second event, I bought a nice APC 1000w UPS, complete with pure sine voltage regulation. All the networking gear got plugged into that. It didn't help at the second event, or at least not much, but it was a worthy investment anyway.
So for the upcoming third event, I've bought a netbook-sized cooling pad for the router to sit on. It's been running on my bench at low speed for a couple weeks now and is cool as a cucumber, but of course that's not the same as outside in the heat with a ton of network traffic. I'm hopeful this will help but I want a Plan B.
Is there a way I can make an ad hoc ethernet connection so I can plug at least one of the secondary devices directly into the main computer if the router decides to take a powder again? That wouldn't help with the crowd of pesky drivers but it would at least let more than 1 person administer the event until the router decided to return to duty.
Any advice is appreciated. Thanks.
