Enable Wireless Uplink on Solo/Standalone Ruckus APs

You can use the procedure below to bridge your AP to an existing WiFi network.

NOTE: This procedure has stopped working for the latest (100.0+) firmware releases.
Make sure you have a 9.6, 9.7 or 9.8 firmware installed before following these steps.

This may be useful if you have wired-only devices (e.g. printers or SIP phones) but can't easily run an ethernet drop.
Or maybe your router's WiFi signal is weak & it has no user-accessible ethernet ports (e.g. an LTE travel router or a phone hotspot).

Step 1: SSH to the AP

$ ssh 192.168.0.1 -oKexAlgorithms=+diffie-hellman-group1-sha1 -oHostKeyAlgorithms=+ssh-rsa -oCiphers=+aes256-cbc

192.168.0.1 is the default IP address, unless the AP was able to lease another IP from a DHCP server.

Login.

Default username is "super", password is "sp-admin".

Step 2: Convert WLAN "Wireless16" into an uplink

Paste the following into the AP's CLI.

NOTE: you will need to modify the last two set rpmkey commands to contain the correct uplink SSID and passphrase for your environment.

rkscli: set rpmkey wlans/wlan15/wlan-cipher-type 2
rkscli: set rpmkey wlans/wlan15/wlan-encrypt-state 1
rkscli: set rpmkey wlans/wlan15/wlan-encrypt-type 1
rkscli: set rpmkey wlans/wlan15/wlan-if-flags 1
rkscli: set rpmkey wlans/wlan15/wlan-init-noup 1
rkscli: set rpmkey wlans/wlan15/wlan-userdef-text WirelessBridge
rkscli: set rpmkey wlans/wlan15/wlan-wpa-type 2
rkscli: set rpmkey wlans/wlan15/wlan-wpa-eap-enable 0
rkscli: set rpmkey wlans/wlan15/wlan-type sta
rkscli: set rpmkey wlans/wlan15/wlan-state up
rkscli: set rpmkey wlans/wlan15/wlan-ssid REPLACE_ME_WITH_YOUR_SSID
rkscli: set rpmkey wlans/wlan15/wlan-wpa-passphrase REPLACE_ME_WITH_YOUR_PASSPHRASE
rkscli: reboot

Your AP will now reboot, and associate to the WLAN you specified in step 2.

You won't be able to choose which 5Ghz channel is used anymore. The AP will use the uplink's channel for all 5Ghz WLANs.

You can choose a different WLAN to convert, if you're already using Wireless16 for something else or you require a 2.4Ghz uplink.
Just tweak the script, changing wlan15 to whichever of wlan0 - wlan7 (for 2.4Ghz uplink) or wlan8 - wlan14 (for 5Ghz uplink) is free.
