I got a broadband connection at home from GTPL . The guy set up the connection on laptop instead of router because I refused to buy a new router from the company.
Now the Internet runs fine (good results on SpeedTest) only on that specific laptop. If I put in the same credentials on a different laptop, it doesn’t connect. I get error 691 from win 7 and on xubuntu (15.04) the connection silently fails.
So my question is: Does PPPoE/my-cable-connection implement something like a “User-Agent” string? If so, how can I overcome it (spoofing?) and connect to Internet without submitting to ISP’s will? Because it’s really weird that the Internet works only on the machine that it was initially configured on.
