(Apple also added a number of tweaky options in its Wireless Diagnostics program, which you can open from the hidden Wi-Fi menu. If your noise value is very high (like -30 dBm instead of -90 dBm), there’s interference from other devices, Wi-Fi or otherwise, in the same band, and you again may need to move the base station or pick a different channel. If you always see 20 MHz in the Channel line, but the PHY (physical protocol mode) is 802.11ac, you have other networks in the vicinity on the same or adjacent channels that are forcing the base station and client to negotiate a slower rate moving the base station or forcing a different channel could help.

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. The Disconnect from item is a nice addition.Below a currently connected network, in addition to the previously available details, you see the Mac’s assigned IP address, the router’s address, and whether or not the Internet is reachable. At the top of the menu, the Unix-based interface name (like en0) appears, along with the Wi-Fi adapter’s factory-set unique MAC (Media Access Control) address. Network information is now scattered about.These help you diagnose network problems quickly, without the need for other software. Yosemite adds a new option to the hidden menu as well as several new bits of network data. For the last few releases, it has contained seven pieces of data about any network to which you’re connected and five items about others, visible when you hover over their names. With iOS 8.1 installed, Yosemite also adds a nifty way to activate Personal Hotspot from your Mac instead of your iOS device.Īn Expanded Menu of Hidden Data - The Wi-Fi menu (previously known as the AirPort menu) has long concealed a hidden treasure trove of performance and connection data that’s revealed when you press the Option key before clicking the menu bar icon. Wi-Fi is a mature part of OS X, but Apple likes to tinker, and OS X 10.10 Yosemite brings a tinkling cascade of tiny changes, from new information and a new way to display data in the Wi-Fi menu to removing the last vestiges of the long-outdated and completely broken WEP (Wired Equivalent Privacy) encryption protocol. 1672: The hidden power of Google Sheets, Launchpad usage levels, Emergency SOS via satellite in the Maui fires, do you use proxy icons?.1673: macOS 13.5.1, watchOS 9.6.1, copy data from Web tables, what Spotlight is used for, do you use Apple’s Weather app?.
