Please help us to make overview of the default passphrase strength for different brands of home router. Please add your router also if it comes with a good key.
The resulting list of this passphrase properties will be published and regularly updated on our site: https://www.agrs.tu-berlin.de/wpa
Furthermore, we are also doing other projects with router and it would be great, if we could ask you to answer some more questions in another questionnaire or if we could contact you to verify a finding on your router.
But even if you do not provide any of this information: Thank you for helping us.
