So I decided to run the 4500 in 5ghz and turned on the 2.4 radio on my fios router for those devices. So far the xbox is getting better speeds, and signal. I did notice something though. Once I switched to 5 ghz, under gamefuel tab the measured uplink now says not measured instead of the 66500 that it was before. Any idea why that is? I've tried to reboot the router numerous times, and it still reads the same.
