Thanks for the answer.
Actually, i decided to reboot the cable modem by unplugging it and see if it would change anything and what do you know?? It did.
I now have 4 down and 3 up.
Another quick question.
Should i be using a 2 way 3.5db splitter instead of a TAP splitter?
It is may be better this way since the tap out has a 9db attenuation if am i not mistaken...
