wireless radio 'off' on latest update (by usb)

[acheck]

I just tried to update my daughter's xo. First tried while connected wirelessly to our home net. We waited and waited. Finally did a USB update and it worked fine - it seemed.
But for 'step 8' I had to sign back into our home net but it seems the wireless radio is turned off and I can't find where to turn it back on. Checked the control panel - 'network' and I un-checked the 'Radio' box (and I tried it checked again too) so it was in 'regular' power saving mode.
The little wireless 'mic shaped light' on the front panel won't come on.
where can I access that? It did say that the update occurred successfully.
thanks

Ok - Got if figured out (don't know what happened still but....) did a restart from the home menu and when it came back the good old wireless 'mic' light was blinking away and found our net.
"crisis averted". I can go to sleep now and she can have it - updated - in the morning.
