I take the train to the city every day and I have been seeing my connection suddenly switch to ‘xfinitywifi’. This was getting very frustrating as I didn’t want to be on a public wifi and it was switching off of my hotspot or home network. It was not in the list of managed networks either. I found out that Comcast was automatically registering your Hardware MAC address and it would try to connect anytime it was in range.

The following steps helped to remove my Hardware MAC address from there system.

Login to Xfinity.com

1. Click “My Account”
2. Sign in — You must have access to billing to do this —
3. Click “My Services” tab
4. Click on “Xfinity Internet” on the subtab under “My Services & Equipment.”
5. Select the “Manage devices for hotspot access” option
6. Manage or remove the devices from your account by clicking “remove” next to each one you want to disconnect.
