Epson wireless-enabled products
This problem is related to your wireless router. For example, it may be related to the security level setting or wireless channel. We recommend that you contact the router manufacturer for assistance, or try using a different router.
As a workaround, try to wake your Epson product from sleep mode by pressing any button, except the power button, on the product's control panel, and then try printing again. Alternatively, power off the product and power it on again before you try to print again.
We recommend ensuring that all wireless devices are using the same wireless channel; this is a setting on your router. Channels 1, 6 or 11 ('11' is often the default for UK devices) as many devices work well on these channels or preferably use the Auto setting if this is available on your router as this will automatically select the best channel. If you change the setting, power off all devices and then power them on again to check if the change has taken effect and resolved the issue.
Many wireless routers have a choice of wireless security modes such as WEP and WPA2. WPA2-PSK (TKIP) Security (WPA Personal), a commonly-used protocol, and WPA2-PSK (AES) offer a strong level of security. Combined security modes such as WEP+WPA2 may not be supported.
For more information, contact your network administrator or wireless router provider and refer to the documentation for assistance.
