@rs1x, How is your miner's pi connected to the internet? Is it connected directly to your router or does it go to an access point?
The Routes page is missing a gateway, and cgminer's api is telling you it cannot connect to a network. That's the issue; the cause could be many things.
Parallel miner said it's configured for DHCP. I don't know that I beleive the rasp pi is.
Did Parallel miner sell you the pi? I'm wondering if you have the wrong version of OpenWrt is installed for your pi. You may just want to reflash the pi with the correct image from Canaan.
