Computer Security & Viruses/UPnP?

Question
Hello,

I am using Windows XP and Privatefirewall 7.0.Today when I was viewing my firewall log, I noticed there had been incoming UDP packets from IP address 192.168.1.1 , which if I'm right is my router.My laptop is connected to the router via Wifi.The internet
connection is private and Im not using other devices so I don't understand why my router sent me UPnP packets.

So in the advanced report it says:

Remote IP: 192.168.1.1:1900(UPnP)
Local IP:  192.168.1.2:1912
Protocol:UDP(17)

So my question would be:
Do you think this was a hacker?
Are there any other reasons?

Answer
What makes you think it was malicious?  UDP packets can be obnoxious but I don't see where they'd be especially useful on their own, in an attack.  UDP in a denial of service attack is old hat.

Please refer to the main (first section) here:
https://en.wikipedia.org/wiki/User_Datagram_Protocol

then this Sub-section:

Hope this helps.
