Apple80211Associate2() failed with error -3905

Question

I have been experiencing a bit of a problem with my MacBook Pro at work and our tech team don't seem to know how to resolve it without a full system reboot, which I would like to avoid. The problem is when I connect to a specific network I get this

I am still able to connect to other networks it is just this one that I can't seem to connect to, but I can also still connect to this network with other devices it is just this one MacBook Pro that I can't connect with. I know the password is correct so it isn't that.

I have trawled through loads of sites over that the few days and found nothing, that explains why this is happening or how to resolve it. I found one site that said to run a script in terminal to get the error could so I did and here is the output I got.

When I got this I started searching for errors associated with Apple80211Associate2() failed with error -3905 and got quite a few I found a lot of forums say it was from an update to the OSX but I haven't done an update in a while as there is nothing to update.

I also had a look at AirPort fails to connect to existing networks after Repairing Disk Permissions but it doesn't explain how to solve this issue

Please can anyone help me resolve this issue it is putting a huge delay on my work.

Answer 1

Check if MAC address filtering is enabled on this network, and that your MacBook Pro's MAC address is in the list of allowed MAC addresses.

AirPort Expresses can be configured to filter clients based on a MAC address list. Any device whose MAC address is not in the list will not be able to join the Wi-Fi network.

In other words, every device connecting to an AirPort Express configured this way will need to have their MAC addresses entered into the MAC address list. This is done through the Airport Utility. AirPort Utility is available for OS X, iOS, and Windows. Additionally, AirPort Utility also allows a single line comment/note for each MAC address entry.

If a device was able to connect before, but can't now, then maybe its MAC address was actually removed from the list (maybe because someone forget to fill in the info for your MAC entry).
