Q: What causes error "Network Host 192.16x.0.1 is busy. Will retry in 30 seconds."

Wireless Printer error shows network host as busy. Cannot reconfigure to re-connect. It was printing ok. Then I tried to scan a doc and then it wouldn't print again. I have internet access. Receive email, etc.  Tried reinstalling the printer software several times. Printer says it has successfully completed connection to the Router. But I continue to get the error "Network Host is busy. Will retry in 30 seconds." And it never prints. Also, printer config option is greyed out.

1. What root cause generates that error message?

2. What settings should I reconfigure?

3. How do I re-configure settings?

I am not a techie...a busy frustrated Grandma at home. Need step by step, just to get to the right menu.

Thanks for help.
