Wireless Security Alarm

With DSL is it normal to have maybe 2000 inbound access attempts in 3-4 days with Zone Alarm Firewall on High? I recently put my Zone Alarm firewall on High and have 1950 intrusion blocked since last thursday when I put both securities on High and the firewall has blocked almost 2000 access attempts. I also put Zonealarm on my roommates laptop, she has Wireless and in the same amount of time shes had less than 200. What is the difference between DSL and wireless and is the the amount of attempts Im getting normal? Im just curious if theres a reason this might be.
