Surprise!!!!
The WP power supply is not putting out too little voltage..
Its putting out to much!
While running it, it usually sat at 5.3 volts. However a few spikes went a bit higher. When it reached 5.4-5.5 volts, I lost my net connection. I noticed on large transfers it will occasionally slowly rise up. Teh Power supply is putting out 5.4 with no load.
Some nics are obviously more fault tolerant on this.
May also explain why these run so hot. Since who knows how much of the system is over volting. If I can get Motherboard Monitor to work on here in the near future (I doubt it will pick anything up), maybe that will give us some more info.
I checked on my main system to verify I was testing the right way, and if my voltmeter was off, it was perfect at 5 volts.
By the way, Boosted, That should work, but I am no electronics expert.
