HP officejet Pro 8620 stopped dropped from network

[Confused30]

This morning my printer was working fine. Now it says it's unable to connect to the wireless router. 
Report says "If MAC address filtering is enabled... and then it gives options I don't understand. -- but it was working two hours ago!
On the report it lists the Network name (SSID) correct -- just entered it again.

Than a MAC address 94:57:a5:99:21:d4 (whatever that is)
IP address........... "not applicable", etc.
------------
I have a meeting to go to later and need to get this fixed to print stuff. Any ideas? Thanks.
