Question on New LG Washer (WM340OCW) and the *signal feature

Bought these “smart” washer and dryers that use LGs app. I assumed they worked like my LG ranged and used wifi. However I have not been able to enable the wifi on the washer nor dryer. The manual says to press and hold the Delay Wash button for three seconds. To trigger the buttons second option *WiFi. But of course my manual doesnt match my product. There is no *Wifi noted on the Delay Wash Button BUT there IS a *Signal under Cold Wash on the button above. Pressing for three seconds triggers a chime and thats it. I then found an online resource that let me do the Smart Diagnoses with my phone mic and it worked. I am guessing there is no wifi on these machines but what the heck is *Signal? NOTHING is documented anywhere. Thanks!
