Every day it just seems to be getting slower and slower and i have no clue why.

Nothing is using my bandwidth, im the only computer active on my network, and im not using any net. 

Ive tried rebooting my modem, but nothing seems to be working.

Anyone know whats going on?

And yes i know my sync speeds should be higher, i need to get a central splitter installed, but no clue where to get one. Could anyone help? Im in West Auckland
