Arduino Nano + 28J60 ethernet shield problem

hello everyone,

this first encounter arduino nano , ethernet shield , have run problem. there have been few, arduino nano not being recognized windows when shield or external power connected.i solved shorting test + agnd pins on ftdi chip. bumped else, either related library or faulty shield guess :~

setup:
arduino nano rev3
shield: http://www.ebay.com/itm/ethernet-shield-for-arduino-nano-uno-r3-work-as-enc28j60-rj45-webserver-/170972854883?
6v external power supply 2100ma
router: linksys wag200g
library: ethershield/ethercard (ethershield provided seller, wouldn't compile without changing wconstants.h android.h in enc28j60.c)

i have tried whatever examples in these libraries related dhcp, ping, webserver. tried letting dhcp assign ip trying static one. shield never became visible in dchp table , ping attempts fail. on webserver example, typing ip on browser yields nothing. though can see shield , router communicating because router's led blinks @ same time 1 on shield. (if can indication of anything). shield never assigned ip. @ least correct one, when tried serial.print ip, gives 5.5.5.5

all examples , tutorials have found on web simple , straightforward makes me think faulty shield. or push in right direction appreciated.

regards

you should step step.

power supply
you need multimeter measure voltages.
is nano running @ 5.0v ?
is ethernet shield running @ 3.3v ?
are voltage regulators getting hot ?

connecting shield
do know pins used ?
for example ss (or chip select) can pin. pin used in library , must match hardware.
do have schematic of shield, if not, why did buy it  :~

sketch
i tried few libraries, , think ethercard library best. it's library enc28j60 good.
you should know if communicating enc28j60 chip.
try see if functions returns error , print lot serial monitor see going on.
