Thanks for the fast reply,
Please do the following:
Turn off all the pc's / laptops.
Unplug both the router and the modem from power.
Directly connect the ethernet cable from the back of the modem to the laptop.
So that the router is out of the picture entirely.
Now first off, turn on the modem, and wait until all the lights are lit and steady
Once this is done, turn on the laptop
Make sure and firewalls are off on the laptop.
See if you can connect to the internet.
Please let me know the outcome
