Yes, setup a local stratum proxy - on a spare unused pc or raspberry pi for example. It is easier than it sounds to do.
You will get much much better efficiency than trying to mine via a remote pushpool server.
Try using stratum via proxy, it is extremely unlikely that your blade is faulty, much more likely that getwork isn't coming in fast enough.
I've tried. On 5 different computers, both wired and wireless. When the blade starts it fetches work from the proxy, I can see the proxy gives it work. It never sends anything back, no accepts. Then after 2 mins or so it restarts and the whole process starts over again.
It will sometimes connect through the proxy, very rarely, but when it does it reads as only doing 600mh/s and the pool reads the same. Its slower through a proxy, when the proxy does randomly work that is.
I'm really hoping its just lack of power. I have it hooked up with 4x black wires and 2x yellow but they are hooked up with jumper wires and alligator clips instead of the plug. SSB shipped me one out express yesterday and it looks like he paid for Sunday delivery, which I didn't even know was possible with usps. lol so I guess I will find out if that's my problem tomorrow.
