How can I forget a hotel wifi network?

Thanks, I was hoping there was a way for me to delete their connection from my end.

Network System Preferences, Highlight WiFi in the left hand panel, click the Advanced... button, then just highlight the network and press the "-" button.

"if they could reset the code, they said no. It expires in 30 days.": If they can't reset the code, then the problem comes from the hotel (network provider) server identifying your devices using the ip or MAC adresses... You tried everything you could do from the device's point of view, so as Apple Support stated, it is the hotel's issue.

I assume other people also have this problem so I wanted to share my solution in case it helps.

This may only be the case in my hotel - but if you log onto wifi on your phone / other device and select the high speed internet - this will upgrade your computer as well (to high speed internet, because you're upgrading your room wifi). If you've already logged in on your phone, you could ask the front desk or someone else to log onto your room through the wifi (select high speed option) through their phone and that will do the same thing.

This saved me a lot so hope it helps you too!

You just need to change your MAC address of machine.

Step 1: Generate random mac address

openssl rand -hex 6 | sed 's/\(..\)/\1:/g; s/.$//'

Step 2: sudo ifconfig en0 ether xx:xx:xx:xx:xx:xx( replace xx with result from above command)

Step 3: ifconfig en0 |grep ether ( Confirm if mac address was changed)

Use en1 in place of en0 depending on connector you are using. Make sure to disconnect wifi before changing mac address of machine.

It WORKS! You must see new wifi address.

Wow, this was great - many thanks!

thank you! worked like a champ
