Alright, I'm going to give this one last shot and see if any experts can help. I have a DESKJET 3070A all in one.
Long story short. I setup my wireless printer successfully, it prints, scans and everything. Then I don't touch it for like 2 minutes, my devices says it can't find the printer anymore. The wireless light on the printer still remains solid blue. Network configuration print out says it is still connected, with IP address of 192.168.0.XXX.
Then I have to unplug the printer, plug it back in and it will print again. Then it stops printing again after 5 minutes idle time.
I tried EVERYTHING including static IPs.
If anyone can tell me how to fix this, I will kudos you like 1 million times.
