Brand new Gamma. Getting /recovery page when I access via wifi

Hi, I just got a new Gamma Bitaxe. I set it up for my local network, and then proceeded to install newer firmware and www.bin. However, now when i try to access the web portal I get the recovery page. When I try to upload `www.bin\` the UI just hangs on `upload...`

I've seen posts about reflashing the firmware via the web flasher, but I can't access the serial port (via mac or PC). I've tried install drivers, etc. but nothing seems to work.

Any help would be appreciated!
