I recently switched offices. The new office is located downtown, so there are multiple access points, both company controlled and external.

The laptop wireless disconnects shortly after I first connect to the network in the morning. It also seems to disconnect when groups of people join the network throughout the day (like, after meetings). I do not have this problem on other networks.

The problem only occurs with Mac laptops on our network. Linux, Windows, and Android devices all seem to stay connected. 

OS X El Capitan (10.11.6)
AirPort Extreme (0x14E4, 0x134)
Firmeware Version: Broadcom BCM43xx 1.0 (7.21.95.175.1a6)
WPA2 Personal
RSSI: -50 dBm
Noise: -90 dBm
Channel: 132 (DFS)
Channel width: 80 MHz

I did use Onyx to collect information about the connection when it failed most recently.

From the bottom of the wifi.log:

I've been told that this is mostly a personal problem and not something IT can help with, so I was hoping somebody here could help.

I have this problem constantly at my office as well. Some days are more often than others. After reading several topics I came to the conclusion that the wireless adapter on Mac is more susceptible to network noise (when many devices are connected to a network) then it drops (sometimes it takes a while to connect). You can do one of the following approaches.

  1. Go to Apple menu -> System Preferences -> Network, Select Wifi and on the settings

Then

then Press OK and then Apply.

OR

  1. Change the router radio channel to 2.4Ghz. Make sure your WI-Fi access point is set to automatically choose the best radio channel to use - as your radio environment changes constantly and the access point needs to be able to cope with this.

  2. If your Macbook Pro doesn't have Ethernet connector, you should get an Ethernet adapter to avoid the frustration.

I hope it helps.

  • I was literally writing a comment saying things looked better and I would be accepting this answer at the end of the day if all stayed that way. . . when the connection died.

  • Unfortunately, The adapter to get connected through the wire will be the problem solver in a noisy network. I've done many things and still it will happen from time to time.
