Connected to Wfi but no internet access

I have windows 7 and comcast xfinity internet. I have two computers that can connect to the wifi but have no internet access. When first connecting to the wifi under the "status" it will say that i have internet access for about 10 seconds before saying that i do not have access. I dont think it is a comcast problem because i tried this with my brothers computer downstairs with the same wifi adapter and it works for his computer.

Any help is greatly appreciated.

  1. Are you using a wireless router or wireless access point?

    In case if it's an access point, you're pretty much limited to 1-2 pc's according to your internet providers settings
  2. It is a gateway, model number SMCD3GNV.

    You will need to connect a WiFi router to your "gateway" aka modem.

    The gateway is a modem router combined with wifi capability.
