Installed Openwrt on Ubiquiti Air Router. However when I try to putty and paste the script from the Location, it reboots and never takes Web interface says I need password. This was updated prior to hotspot making a post to downgrade the firmware of the Ubiquite first before updating it with Openwrt.

Hotspot mentioned setting up a serial connection, but I have a cable to connect to the inside of the motherboard. Any ideas or thoughts to get this going?
