I just received an Avalon 3 290 module, along with a TP-link controller/interface from eHash.com yesterday. I hooked it up to my laptop with the Ethernet cable and was able to access and configure settings through the web interface. I changed the address to my network, moved it, and can still login and connect to it.
What I CAN'T do is talk to the miner, or get it to do anything. I'm using a Thermaltake TR2-600 w power supply.
I see 2 green LED's on the interface board, and the fan runs. That's all.
The CGMiner API log says firmware 20140423, CGMiner 2077365. Socket connection failed: Connection refused.

Can anyone tell me what I am doing wrong, if anything?

Please help. Thanks.
