Ardiuno Ethernet W5100 ic solder bridged? Answered

hi I got a Ethernet shield for my arduino I have ordered, but the problem is that the solder on the IC seems to have run and bridged the connections. I have some pictures taken with a lens I had laying around...

This is what I found.

Please can you help me decide weather I should take it back for a full refund?

Looking at the pcb design, those pads all seem to be connected to ground, so it might even be meant to be like that

does the shield work?

if it's not meant to be that way, poor. Well, I'd ask the seller for a refund...and barring that, get some desoldering braid -- it's cheap online or at an electronics shop (2-10 dollars a roll) and you just lay it over the pins, then heat them to suck up the excess. usually removes most bridges like this.

i havent had a chance to test it yet as my arduino board has not come in the post yet

There are a lot of grounds on that chip, and I ain't going to work 'em all out - check out the datasheet and see what's what

Do you have any idea where i can find the data sheet just google the part number on the IC?

Does it work? Answer that first.
It's probably deliberate since the pins are connected on the PCB anyway.
