Thanks, but that module is already installed here.

Speaking about wifi, what is the recommended way to retrieve available
wifi devices in Lua?  I'm currently doing something like this:

local iwinfo = require('iwinfo')
local luci_sys = require('luci.sys')
local function get_wifi_devices()
   local devices = {}
   -- Retrieve available network devices.
   for _, device in ipairs(luci_sys.net.devices()) do
      -- Is there iwinfo support for this network device?
      if iwinfo.type(device) then
         table.insert(devices, device)
      end
   end
   return devices
end

Is there any simpler way than iterating over all network devices?
