Bypass wifi time limits

I’m currently sitting in terminal 5 of the Heathrow Airport waiting for my corresponding flight. They are limiting 30 minutes of free wifi. One can usually circumvent such limits by spoofing their mac address.

For Mac/Linux:

  • ifconfig and find the active network interface (usually en0).
  • Note the mac address somewhere to revert back once the operation is complete.

sudo ifconfig en0 ether [random_mac_address]
sudo ifconfig en0 down
sudo ifconfig en0 up

For Win7/Win8, it seems that Microsoft forces to use one of those mac addresses: X2-XX-XX-XX-XX-XX X6-XX-XX-XX-XX-XX XA-XX-XX-XX-XX-XX XE-XX-XX-XX-XX-XX. Looks like somnething like this tool can do the job.
