Get to know your AP.
Start with a PoE switch and only your 1st AP and your laptop connected.
Set your PC to 192.168.0.10/24 (anything but .1).
Find the factory reset hole by the Eth port of your AP, and press it for 5-8 seconds, or until the LEDs go out and come back on.
(you might need a paperclip or toothpick)
Give the AP 2 minutes to fully boot up, then open a browser to 192.168.0.1. Login with super/sp-admin credentials.
Determine what firmware is running on your R300 now? (write it down)
================
Put your laptop back on a network with Internet connectivity and reset your IP to DHCP.
Download the latest Solo AP firmware for R300 from our Support site:
https://support.ruckuswireless.com/products/52-zoneflex-r300#firmwares Save it to your laptop, where you can find it again.
Go back to your PoE switch, set your IP to 192.168.0.x and use Maintenance::Upgrade page of AP to install/upgrade your firmware to latest release.
Repeat with AP #2.
You can upgrade from any previous Solo AP version to our latest 104.0.0.1347.
