^The workaround was fairly simple. Upgrade yourself to 4mb then downgrade back to 1mb. On downgrade requests they would only downgrade your username because they were lazy. Everyone's password was ptcl and the username was clearly shown on the modem page.
A really effective way to do this was to access 1 modem and change his password. Access modem number 2 and put user 1's user pass then restart. Put 2's password on 3rd modem and so on. Keep repeating this until you are using user 10's user/password. This created a chain because user 1 would complain and wait for his connection to be fixed, once modem 1 is fixed user 2 would experience problems because they both are using the same pass, when 2 is fixed then 3 will have problems and so on. A user pass would work for 2-3 months for the end user.
With the software "advanced port scanner", it was really simple getting IP addresses of modems with the firewall off.
Since this no longer works, I think there is no harm in sharing if publicly. Another reason to do this was to avoid getting your username above the download quota when they were charging 1000 after you downloaded a specified gb/month
