• If you are connecting the product wirelessly via EpsonNet Setup and you do not see the Wi-Fi antenna icon with connection bars on your LCD screen, make sure your product software was installed correctly. If necessary, reinstall your software. Note: If you are using a 5 GHz wireless router, set the router to operate in dual band (2.4 GHz and 5 GHz) mode. If your router uses a single network name (SSID) for both the 2.4 GHz and 5 GHz band, give each band its own network name (SSID) instead, such as Home Network 2.4 GHz and Home Network 5 GHz. See your router documentation or contact your internet service provider for instructions. Parent topic: Solving Network Problems Related concepts Uninstall Your Product Software Wireless Network Connection is Unstable on a Mac If you connected a device to a USB 3.0 port on your Mac, you may experience wireless network interference between your product and your Mac. If you cannot connect to your product over the wireless network or the connection becomes unstable, move the device connected to your Mac USB 3.0 port further away from your Mac. Parent topic: Solving Network Problems Cannot Print Over a Network If you cannot print over a network, try these solutions: • Make sure that your product is turned on. • Make sure you install your product's network software as described in your product documentation. • Print a network status sheet and verify that the network settings are correct. If the network status is Disconnected, check any cable connections and turn your product off and then on again. • If you are using TCP/IP, make sure the product's IP address is set correctly for your network. If your network does not assign IP addresses using DHCP, set the IP address manually. • Make sure your computer and product are both using the same wireless network. • If network printing is slow, print a network status sheet and check the signal strength. If it is poor, place your product closer to your router or access point. Avoid placing your product near a microwave oven, 2.4 GHz cordless phone, or large metal object, such as a filing cabinet. Note: If you are using a 5 GHz wireless router, set the router to operate in dual band (2.4 GHz and 5 GHz) mode. See your router documentation for instructions. 278
