Taken together, this information can help you sort out network difficulties. Noise is the only new item in the hover-over display for non-connected networks. The -90 dBm (decibels below 1 milliwatt) figure here is pretty good. Available signal is the ratio of signal to noise, and the lower (further away from zero) the noise value, the better. The menu also now displays the country code of the base station, which could be useful if it has been set up wrong, and the noise measurement. The same extra information also appears in other networks when you hover over their names. With 802.11n, a base station can use 20 MHz or 40 MHz in 5 GHz. The Channel item now shows not just the channel (such as 149) and band (like 5 GHz), but also the “width” of the band. Previously, the only way to sever a Wi-Fi link was to turn Wi-Fi off and on or join another network.
