Thanks to budakpisang for this: In terminal, you can turn wifi off and on with these commands networksetup -setairportpower en1 off networksetup -setairportpower en1 on en1 being wifi. Try networksetup -listnetworkserviceorder to see whether that's right for you or not. Here's a one-liner to toggle between on and off networksetup -getairportpower en1 | ...

Wi-Fi dropping and losing Internet connection are two totally separate things. If your Wi-Fi drops, you lose connectivity to everything on your network. If your Internet drops, you only lose connection to the outside world, your internal network is still good. Below is a general picture of a home network with Intenet. (The cable modem used here can ...

Your MCS is zero (0) which would explain why your WiFi is slow. That can happen if there is channel crowding (not only from your devices but neighbors included). You could just change the channel for now 1 to 5 and try. Or you could do a quick analysis of the channels do following: In Spotlight type "Wireless Diagnostics" Click on Wireless diagnostics ...

Usually when the WiFi connection is still active but no data is flowing indicates Chanel crowding (to many devices/users on same channel). If the WiFi is disconnecting that could be number of other reasons. But since you are talking about the speed going down... When the MCS index is zero (0) then the channel crowding is a issue. The MCS needs to be at ...

Boot the computer to Recovery (hold Command and R on restart) and ensure it connected to your WiFi network. Then select Get Help Online. This actually loads a file stored in Recovery, so type in a URL and see if it loads. If it does not, your computer is not the issue.

I was having a similiar issue with 10.10.3 which was not corrected when I updated to 10.10.4. Many, many things were tried before I got it to stay connected to WiFi reliably, however deleting the networking PLIST files seems to be what finally did it. The Fix: Disable WiFi Open Finder Press Cmd+Shft+G to go to the folder ...

Not in any reasonable manner. Instead, use a portable WISP router. This creates your own local WiFi network yet uses the hotel connection as the WAN. Some are no bigger than your finger if you're concerned about size of this additional hardware component.

Sounds like it might be a bad Airport card, if you have the tools, open it up and then disconnect and reconnect the antennas connecting to the card. If that doesn't work, remove the card, clean the contacts on the card and then reinstall it. If that doesn't work, you'll need to buy a new card, specific for your model of MacBook Air.

It could be just that the Yosemite is not recognizing your Airport card -WiFi function due to the bad setup. Just to confirm, the Ethernet and Bluetooth are working. To check, open the About this Mac and look in Networks for information, showing your hardware and drivers and more. If it shows it there do following steps. Disconnect Ethernet and do ...

I tried to remedy this problem from everything this and other sites said to do. It wasn't until the suggestion to go on the Western Digital MyBookLive to change parameters that I found it needed to be updated. I updated the firmware and the backups started automatically while I took a nap!

You can try to manually connect using the terminal (copy and paste following (one by one). You can skip step one and two, and go to step 3, and enter your SSID and password. Turn On networksetup -setairportpower en0 on Find /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport scan Connect networksetup ...

There's a rather easy solution. Right click your clock, select "Open date & time preferences". Click "Time Zone" and select "Tokyo - Japan". Then either reboot or go to sleep mode. After you power up you should see all of the channels.

Sharing wifi to your phone is a piece of cake. Your computer just can't bridge a network. Go to System Preferences -> Sharing and enable the network. Then connect to it from your iPhone. Traveling on an airplane would not affect the performance of your computer's wifi, and yes, at least in the U.S., you are allowed to do that above 10,000' feet (although ...

The page has now been corrected, which should mean that the popup no longer occurs.

It does sound like you are trying to connect to an enterprise network and you have 802.11x authentication. If this is NOT the case and you need to enter a username/password in a web page, then you may need to create an AppleScript/Automator function to handle that. In any event, to connect to an 802.11x network with authentication, you need a network ...

After lots of fumbling I discovered that the wifi speed is inversely proportional to the CPU temperatures. I installed TG Pro and found that, without altering the internal fan speed or using external cooling, the CPU's would approach 200 F after about 30 min of on time. With TG Pro I was able to increase the internal fan speed (from the built in speed of ...
