This post is not directly related to ubuntu. It is indirectly related in the sense that I use ubuntu.
The issue I have was that the internet in my place was not working for some time. They fixed it, but reset the router and changed all the passwords. Now, I don't think that the default configuration of that router is secure. They have changed the default password and set a password for the wireless. But, that's all. They haven't disabled UPnP. To get an idea of why this is bad, look here: https://www.kb.cert.org/vuls/id/347812 and here: http://www.gnucitizen.org/blog/hacking-the-interwebs . Then, they haven't set wireless security to WPA2-AES. They have set to use both WPA & WPA2 with both TKIP&AES. Their passwords are only 8 characters long. By default, the firewall is disabled. When I told my landlord that this configuration was not secure, I was told that I would have to live with it and they wouldn't give me the passwords to make the necessary changes. Now, in this scenario, can I connect to that network in a way such that my computer and my personal info are secure and safe?
