I was busy doing other things. I got a Western Digital 1TB Network Drive, an 802.11n router and two 802.11n NICs. I spent the afternoon trying to get them all to play nice. It took until 8:30 to get it all straightened out. The first issue centered around the router. It would work fine until I plugged the network drive in. Then it would keep resetting itself. On a hunch, I installed the power supply that came with it. Our previous router was by Cisco and the new one is very similar so I just used the same power supply I already had plugged in. Turns out that the old router only required .5A of current while the new one required up to 2A...which its power supply was able to provide. The other one was not. After that, I spent a little time getting the network drive configured. That didn't take as long. But I'm still working on a sharing issue. Both of our PCs are on the same home group. My wife's PC can see mine...but I can't see hers for some reason.

I am very leary of using any p/s thats from something else without first both checking the output voltage and amperage/current rating and waveform

even if the outplug is the same (likely to be 1 of about 4 `normal' types to choose from), the plugpack can be either dc or ac output, the voltage must match (to a certain degree I use my elec knowledge to know what is a usable voltage range for a type of device..)
however even then if the voltage and waveform type is right, the current/wattage output shown may be wrong- a good rule of thumb is that the plugpack must always be equal to or greater than the (A,mA, mW or W)

then there is the type- unregulated, regulated, switchmode, full or half wave recitified all have different properties, some are interchangable, others aren't

basically my advice is- unles you know your way around electrics (basically you need at least a multimeter and the knowledge to use it) then dont go using any plugpack from any other device - even if the voltage is the same...

(a 12v1a dc + centre pin unregulated plug pack could in many cases replace a 12vdc 1A switchmode- BUT it also has the potential to damage some electronics- where the switchmode can safely replace the unregulated supply in most (but not all) cases-it for eg cant replace the unregulated supply in anything that has a 12v sla battery inside (eg an alarm panel)

best left to the experts- oe be prepared to spend some more $ if you get it wrong...
