Epson Workfoce 545 will not reconnect to Network

Community Member

Okay, I have a weird problem.  I have had Google Wifi for several months now, no problems.  When the guys were here putting everything in I got the app and connected everything, no problems.

This included my printer from the subject.  Don't recall how I connected it wirelessly exactly but it defintiely was.  Right up through a couple of days ago.  I got a new laptop though and was setting everything up with that, and had it connected to the printer (wirelessly).  However I was having some problems with the Epson software (something about the network channel assigned was not supported, never figured that one out either) and as part of the troubleshooting disabled the WIreless LAN on the printer.

I have since tried to reconnect it to my Wifi, and not having any luck.  It finds the SSID no problem, but it is not accepting my password.  From Epson I found reference to 'WEP key is 5 or 13 characters, it’s ASCII. If the WEP key is 10 or 26 characters, it’s hexadecimal' with the password (it also says Your printer supports the following wireless security modes: WEP, WPA, and WPA2). 

When I enter my actual password (8 characters) it will not take it.  I have even changed it to 5 characters per the above to see if that would work and it did not.

I have it connected via wired LAN right now but can't keep it that way.  Any suggestions?  What really confounds me is that it was connected for months and now that I disconnected it recently I cannot get it reconnected.

Here is the current printer LAN info:

Heard back from Epson, how can I do this?  I don't see any documentation on this with my Google WIfi:

Printer can only connect to 2.4Ghz network, since 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.

Hi mrt77,

Thanks for posting ― let's see what's going on.

The Google Wifi point(s) uses the same name for both the 2.4 GHz and 5 GHz band networks. This means that the Wi-Fi network uses both radio bands. But keep in mind: while both bands can be used, the personal devices (a smartphone, tablet, laptop, etc.) will connect to only one radio band at any given time. Nest Wifi, Google Wifi, or OnHub attempts to select the band that will deliver the best performance for your device. Currently there is no option to manually disable either of the bands or to connect to them separately.

Give these steps a try:

Create a hotspot with a mobile phone. However, 2 mobile phones are required:

Use the first device to create a hotspot (mobile phone).

How to set up a mobile hotspot:


  • Go to Settings.
  • Tap the Network & internet option.
  • Select Hotspot & tethering.
  • Tap on Wi-Fi hotspot.
  • Set up the hotspot name and password the same as the primary network.
  • Choose the AP Band > 2.4 GHz band > Apply.


  • Go to Settings.
  • Tap on Cellular. Tap the slider to turn Cellular Data on.
  • Under Cellular, tap the slider to turn Personal Hotspot on.
  • Tap the slider next to Allow Others to Join.
  • Set up the hotspot name password the same as the primary network.
  • To change the hotspot password, under Personal Hotspot Wi-Fi Password.
  • To change the hotspot name, go to Settings > General > About > Name.

  • Use the second device to connect to the mobile hotspot.
  • Disconnect all of the Google Wifi or Nest Wifi points from the power outlet.
  • Connect the device to the 2.4 GHz band of the hotspot with the same SSID and password of the current network (case sensitive).
  • Once connected to the hotspot, plug in your primary Google Wifi point or the Nest Wifi router.
  • Turn off the hotspot and check if the device automatically connects to the Google Wifi network.

Let us know how it goes.
