From the Apple Support database article regarding network connection priority: If you connect to the Internet or a network in several different ways (using Wi-Fi or Ethernet, for example), you can change the order of the network port configurations your computer tries when connecting to the Internet or network. If there are multiple active ...

Do the following: Find out what the network interface is for your wifi. Mine is "en1" for this example (I have obfuscated my MAC addresses with "00") ifconfig en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether 00:00:00:00:00:00 inet6 0000::000:0000:0000:0000%en1 prefixlen 64 scopeid 0x5 inet 10.0.1.16 netmask 0xffffff00 ...

When you're connected to the Wi-Fi network, hold down option and click the Wi-Fi icon in the OS X menubar. You'll see additional details about your connection, including one item labelled PHY Mode:. That will show you whether you're connected via 802.11ac, n, g, etc. There's also a Channel: entry that tells you the radio frequency and channel.

Messages app on Lion or Mountain Lion supports Bonjour discovery which lets computers discover other devices using Messages app on your local network without needing a central server setup. Bonjour is not on by default, but you can find the option under Preferences, or simply ⌘+, to open up the panel. Select the account page, and you will find Bonjour in ...

According to this Apple support page, This will clear your current cellular and Wi-Fi network settings, including saved networks, Wi-Fi passwords, and VPN settings. So, it will reset your network connection options, and it will affect internet connectivity, both GSM/GPRS/EDGE/3G/4G and WiFi, but it shouldn't impact "classic" telephone services, ...

In 10.8.3 and lower, the program Wi-Fi Diagnostics is the tool for measuring RSSI and signal to noise ratio and scanning for hot spots (a.k.a. war driving). That app is gone on 10.8.4 and is replaced by Wireless Diagnostics that does many but not all the same functions. Bonjour scan is out for instance, but the scanning and measuring tools are far better in ...

The 802.11 specification has a standard for Beacon Frames that get sent periodically to broadcast all the details about a particular hotspot. All Apple hardware for Wi-Fi implements this specification and the radio just has to listen for beacon frames over a period of time and present those options to the software. I don't have a analysis or trace of the ...

Assuming the WiFi connection has enough bandwidth for audio, you could install Skype and use SkypeIn/SkypeOut to be reachable via a phone number.

With regard to modifying the system AirPort icon, I do not believe that what you are asking for is possible. To show internet connectivity, I use a combination of WiFi Signal (which could be substituted for the OS X AirPort menu bar item) and Cloud: AirPort off AirPort on & not connected AirPort connected & no internet AirPort connected ...

1) If you have a Mac connected to the same network, you can find the stored password in it's Keychain using the Keychain Access app 2) If the router is an Apple Airport based device, you may be able to log straight into it via Airport Utility (available on Mac and iOS) to see the password at source 3) If you are on iOS7, then you can use iCloud Keychain ...

Reading this question reminded me that I had dealt with the same problem with my Mac awhile ago. I fixed it by writing a shell script which was automatically called via launchd whenever /Library/Preferences/SystemConfiguration/ changes. You'll have to configure a few things, mainly create a list of known SSIDs and passwords for the networks that you join. ...

The wifi signal indicator only reports on the strength of the signal from the base station. It does not indicate if you have internet connectivity. If all of your other devices are connecting through the same base station and router, I suggest you click on the wifi indicator, and select open network preferences. From there it will indicate the status of ...

RSSI or Received signal strength indication is what is used for the display of the bars. The higher the number ( closer to 0 ) the better your signal strength. For Apple devices they used a scale of -100 to 0. But you'll never see 0, or even close. Most people will see a number between about -50 and -80, with around -50 being excellent. -50 will show all ...

The preferred connection is shown at the top of your list. This doesn't mean that the iPhone USB connection will never be used; but, it makes it less likely. You can control which connection will get precedence with the gear icon at the bottom of the list window you showed, and select "Set Service Order".

Hold Alt when clicking at the AirPort icon on the menu bar. It should say PHY Mode: 802.11.x, where x is the type of connection. You can also launch Wireless Diagnostics from that menu to capture packets and graph signal and noise measurements.

The option is not available because you have selected to share your connection from Wi-Fi. You can't share your connection from Wi-Fi to Wi-Fi. Use an alternative method of obtaining a connection to the internet (e.g. Ethernet) so that the internet connection can be shared over Wi-Fi.

Your Mac will only automatically join Wi-Fi networks which are in its preferred networks list. If the non-secure network is not in that list, it will not join it. If you want to be prompted to join a network when no "known" network is available, turn on "Ask to join new networks." However, if you do not turn on "Ask to join new networks" then your Mac ...

There are two things you can do here. If you want all your traffic to go via built-in Ethernet if both Ethernet and Wifi are up, you can make it more preferred in System Preferences: System Preferences -> Network will show you the window with all Network connections defined. At the bottom of the left hand side panel (with the list of interfaces) ...

The spinning circle icon is simply a means of indicating that network activity is taking place, i.e. loading new data in Facebook or Tumblr. It has nothing to do with which network is being used — for that, check the cellular/Wi-Fi indicator. If the Wi-Fi icon is there, then it's the Wi-Fi network being used. It's also worth noting that apps can turn on and ...

You can also try using the awesome mosh project. It will gracefully handle network losses, machines going to sleep, etc and happily restore the connection when you have a working network again. Another more time-honored solution is to use tmux on the remote machine. In that case you may still get a broken pipe, but if you reconnect your shell and ...

No, there's no such option / preference. You could, though, turn off your carrier's data plan altogether by turning off the Cellular Data option (under Settings / General/ Cellular on iOS 6 and Settings / General / Network on iOS 5).

In OS X 10.8.4, Apple replaced Wi-Fi Diagnostics with Wireless Diagnostics. That’s why you can’t find it. Specifically, from Apple’s Support Base article about Wireless Diagnostics: Wireless Diagnostics is included with OS X Mountain Lion v10.8.4 and later. Finding the advanced network utilities described in that CNET article is explained in this Apple ...

The first step would be to open the folder /System/Library/CoreServices and run Wireless Diagnostics to get to the Utilities window (⌘+2) and run a wireless scan to check on your base station and whether the antenna on the Mac is picking up signals similar to your other devices. You'll want to inspect your base station (match the BSSID with the Mac ...

If the iMac is indeed limited to WEP security, an alternative would be to use a 'wireless gaming adapter' such as this one. Originally marketed to Xbox 360 users who did not want to buy the official wireless adapter, these devices handle the wireless connection (using stronger WPA/WPA2 security) and provide an ethernet connection to the iMac.

Discussions of willpower aside, my research suggests that the file you need to copy to the USB stick and later restore is /System/Library/Extensions/IO80211Family.kext. This will require a reboot to take effect. Before removing any system files, be sure you have a working bootable backup of your system and time on hand to restore things should anything go ...

Since I wrote this post my Internet problems seem to have gotten a lot better. As far as I can remember, I only made two more changes. I can't say for sure which one of these helped, or if either them helped at all and maybe there was some other factor I'm forgetting, but they may be worth a try: I changed my DNS settings to use Google's Public DNS. I ...

You can use ControlPlane where you can set up rules based on various criteria. ControlPlane supports multiple contexts where a context is defined as a location or activity you are performing. Using evidence sources you can create a set of rules that tell ControlPlane what context to apply to your environment. When ControlPlane enters or leaves a ...

Although your iPhone will use WiFi when available, that's only to save your cellular data limit being reached as quickly. Your iPhone keeps the 3G antennas active (while the internet is in use) for the following reasons; In case you have 'flaky' WiFi; your iPhone will switch between WiFi and cellular without you noticing to keep a reliable connection ...
