Also I'm using the Router method (Linksys WRT610N v2 with DDR-WRT), so I didn't jailbreak my iPad.
Since you're using DD-WRT, try increasing the transmit power on the radio. You'll get better range

Start with 120mW, and see if you notice a difference and better signal strength, when you're viewing the bar graphs in DD-WRT
BEFORE removing both metal plates:
Range: 2-3m (will have max. 30-40% reception power)
Time till shuttersnitch starts receiving: Up to 1 minute
The first JPG always takes longer to upload. Subsequent JPG's will take less, once the card is connected to the network.
Time it takes to transfer JPG image (in small res): 15-20sec (with occasionally transfer error)
I'm not familiar with ShutterSnitch, but you should never get transfer errors. With Eye-Fi software and Eye-Fi cards, the system self-corrects and retries. But I heard that ShutterSnitch is solid.
AFTER removing both metal plates:
Range: up to 8m (for previous distance of 2-3m my reception power increased to 70%)
Time till shuttersnitch starts receiving: ~10secs
Time it takes to transfer JPG image (in small res): 5-10sec (so far no transfer error)
As mentioned before, with solid Wi-Fi, you should get 12mbps, which is 1.5MBps. If you're shooting RAW + JPG, and the JPG is tiny, lets say 1MB, it should take about 1 second per JPG. Don't forget that some of the delay is the card writing the RAW image, and not uploading. Only once the card is done writing the files, does it resume to upload. If you would like to verify what I'm saying, turn RAW off, and just shoot small JPG's. You'll see that they'll fly right in.
So as you can see, I'm quite happy with the results after removing the metal plates. Total delay time of ~15secs to get preview is ok for some general use. Of course it doesn't compare to real tethered shooting via USB cable to an iMac. But hey, its wireless and if a client comes over to get some easy previews in his hands is great

Try also changing the channel on the router, from the default channel 6, to 1 or 11, and see if you'll get more range, which will improve your speed.
