Is the coach new? If not, the previous owner may have hidden the SSID on previous setup. If so, proceed to the reset instructions below. Otherwise, continue:
Is this the power switch you are turning on for WiFi?
My switch was installed upside down so most importantly make sure it is depressed on [|] not off [O].
Per the manual, it needs a few minutes to boot up. The SSID or Wireless Network name you are looking for is on the label on the front of your owners manual.
If you are unable to see the wireless network then you may want to verify power to the device on the roof and then perform a hard reset. Take up a small Phillips screwdriver (and a dark bath towel to block the sun when checking the LED if bright outside) to remove the SIM card plate and follow the instructions below to verify you have a green LED light and/or reset the device.
If after this you observe no LED light (mine was faint on a bright day so cover your head and the device to block out the light) then you need to make sure you don’t have a blown fuse. You’ll have to share your coach mode and floor plan for us to help you find the fuse location.
If you’re not comfortable on the roof then please take it to the dealer to look at.
Good Luck!
