No, this is nothing more than a switch for networking wired devices. If you connect it to your modem, you can only plug in one wired device that will have internet access as it does not route Information. You will need a wireless router to accomplish this. A router allows you to take one IP address from your internet service provider and allow multiple devices to connect to it by routing to a newly established network. Without a router, only one device can connect to your modem if it does not have routing capabilities. The best way to know is to see if it has multiple Ethernet ports on it. There will be a WAN (wide area network) and a LAN (local area network). The WAN is your internet access and the LAN is your local devices. Hope this helps.
