How often does it do this and what is it actually sending? Most analyzers will let you save a packet as text. You could copy and paste it into a message to us so we could take a better look. These packets probably aren't really using much bandwidth unless the device sends them very frequently and they are big packets. Every NIC must process the broadcast and pass it up to IP to determine that it can be trashed, so if it happens a lot, it could be related to the complaint about the "network being slow." If it doesn't happen a lot, though, then it's probably not related to the complaint.
