Wireless printing - currently offline

[Mschmitt]

Hello,
The security key on my router was changed via AT&T. My wife still prints as before to the wireless Eson printer. I cannot print to this printer. (I was able to previously.) How / where do I enter the new security key (SSID)? I know the key. I cannot find where to do this. Thanks.

The SSID is the router's broadcast name. If your wife is still able to wireless print (not via USB or ethernet cable) to the Epson, then the only change should be your PC/laptop's wireless connection. Can you surf the web on your device using your wifi connection? Are you connected to a GUEST wifi instead of the same wifi network your wife is on?

The printer should be able to tell you under it's setting or by printing a config page on what IP it has.
What model is your Epson?
What is the IP and subnet of the Epson?

What is your PC/laptop IP and subnet?

You could also download the latest software + driver for your Epson printer and go through the connection wizard again.
