The xcvr2450 will work happily with gnuradio 3.2.2 and 3.3.0 (probably
earlier versions and definitely the latest git master)

Have you tried usrp_fft.py?  Use a command like:
    usrp_fft.py -d 16 -f 5.0GHz -R A

Have you tried it on both sides of your USRP? (change "-R A" to "-R B")

Have you tried more than just the 5.0GHz frequency?  Try something in
the 2.4GHz band

Did you try both antenna ports?

Try using a Signal Generator to inject a sinusoid at 5.001GHz and
-40dBm.  Can you see the sinusoid in your usrp_fft.py window?
