T55A Upgrade 58.15.0.85 Netowrk Unavailable - how to downgrade or restore?
I tried to upgrade a T55A to .85 firmware. Now when it restarts, it says "Network Unavailable". I've tried factory reset and everything I can see in the GUI and nothing will restore network. DHCP does not work. Static IP assigning does not work. Please help.
