Cannot join wifi network - "please move closer"
Just to make sure, check with network admin that your MAC address is not blocked :)

The message posted indicates you might have a Firewall setting issue.

Open About this Mac + more info + system report and find the Firewall. Check the settings there making sure it is not blocking that network somehow.

Also make sure you do not have a 3D party Network software blocking that connection like Little Snitch or others.

Lets try to connect manually, using the Terminal:

Follow this guide to connect using copy paste.

In Terminal type following (to turn the airport on)

networksetup -setairportpower en0 on


Next type (to scan for networks and find the one you want)

/System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport scan


Finally type (to connect)

networksetup -setairportnetwork en0 WIFI_SSID_I_WANT_TO_JOIN WIFI_PASSWORD


If the password is something weird like ASCI or HEX follow this guide.
