Connectivity problems with WIFI

In the past months, we have detected an increase in the number of incidents related to the WIFI network, mostly affecting Macbook Air. Lack of velocity of the WIFI connection, trouble connecting or continuous disconnections from the network are the most common problems we have observed in this type of model device.

Unfortunately, this problem not only affects the IE network, it is a general problem to which the manufacturer has still not found a solution.

There are some workarounds that mitigate this problem.

  1. Disable completely Bluetooth.                 
  2. Modify the maximum size of MTU of the WIFI card to 1453.
  3. Disable AIRDROP
    • To disable the service from the console: sudo ifconfig awdl0 down
    • To enable the service, from the console: sudo ifconfig awdl0 up
