Hi my name is ***** ***** I can assist. What is the model of your Epson printer and your switch?
On the TM-T88V, the dip switch setting is this:
DIP SW 2-8: ON
DIP SW2-8 On: refers to the switch number 8, on switch bank 2, is turned On
It sounds like the printer is configured for the wireless if the printer shows in Windows, however if you want to get to the configuration and EpsonNet cannot connect to it through the wireless, you can connect the wireless card to the configuration computer with a USB cable and access the configuration that way. It appears that you Dip Switch settings are correct.
Have you tried resetting the WiFi adapter and re-configuring it? Use the pin hole to reset the configuration.
I'll go ahead and opt out so you can wait for jcmoore. I'm not sure when he is on but if any of the other experts pick up your question, just tell them that you are waiting for his response.
