Singnet 10mbps is slow, especially at night after 10pm. It's
crawling at dialup speed for me after 10pm. It only resumes normal
speeds after midnight.
As for downloading wise, if you use it during off peak hours, it
can be fast. Try using peak hours and it can take a whole
day.

Your wireless router won't be compatible with the current

that's your first time using it. If I'm not wrong, it will be
free.
You can't use the same configurations as well, but you will use the
same username and password. You can change the password if you want
to.
