I dont know why but linksys looks like they like starving their Wireless Routers and AP's of POWER. They supply you with a .5 to 1.5 amp switching power supply way under what you need . Look a the product spec sheet for a WPC300N PCMCIA WiFi card;

Power Consumption TX: <900mA (Maximum) RX: <700mA (Maximum) http://downloads.linksysbycisco.com/downloads/WPC300N_ds,0.pdf


Look at what the BCM4705 CPU Power Consumption is; 5v @ 2.4w = 0.48 amp just under 1/2 amp. http://www.broadcom.com/collateral/pb/4705-PB01-R.pdf

the switch BCM 5325 Power Consumption is 5v 1.4W = 0.28 amp http://www.broadcom.com/collateral/pb/5325-PB05-R.pdf

also add the RAM power consumption (unknown at this time)

Remember the varation that is needed; normaly 5% to 10%

Power needed just for this item at minimum so far: 900 ma 270 ma 480 ma total: 1650 ma which equals 1.65 amp

Other Routers have this problem to!!
