combo, also, is it just unplugging the wire into my computer from the router's end or do i do something else?
only have one computer
First, Unplug the connection from the back of your computer and wait a few minutes.
If that works and fixes things. Congratulations.
If that doesn't work, try resetting your modem.
If that words congratulations.
IF that doesn't work, either one of your boxes are dead or it's your ISP.
The last alternatives is checking your connection settings and try fixing it through your computer.
