You will remember that wide channels are the method by which you can boost the throughput of your Airport Extreme access point to up to 300Mbps, if your local laws allow it. It used to be set by, in Airport Utility, going into the wireless options, choosing a country that supports it and ticking the “Use wide channels” box.

This functionality may have been recently removed, however. While testing network connectivity today using our favourite wLAN graphing software, AP Grapher, we noticed that our maximum bandwidth was 130Mbps. Yet we still had wide channels selected. We’re unable to find a way of getting 300Mbps right now, using the current 7.3.2 Airport Extreme firmware.

Can anyone else confirm they’re having the same issue, or is it unique to us?
