A:AnswerHi, Alex. The Linksys SE1500 doesn't have a wireless capability and needs to be connected to a router via Ethernet. If your desktop computer is wireless capable and your wireless network doesn't reach your room, you may consider getting a range extender.
A:AnswerYes. I have 2 computers & a magicJack (VoIP) phone but my modem has just one outlet. All 3 devices are plugged in to the switch, then it to the computer & everything works just fine. And of course there's still an open port I could plug another device into -- comes in handy when a friend of mine stops by with his laptop 'cause I don't have or want Wi-Fi.
A:AnswerYou shouldn't have any issues. Think of this switch as one of those adapters that turn one electrical outlet into 2 or 3. All it does is turn one Ethernet port into four; all devices connected to it will receive DHCP and other data directly from your Motorola modem.
