    Any recommendation for a Network Bandwidth analyzer? I would like to find out who's using up all of the bandwidth in our network, from internet radio to gaming.

    You can download wireshark. It is probably the best freeware network traffic analyzer.I

    t will analyze all network traffic and the captured data can be filtered. It is fairly straightforward. Once you have got the hang, take a look around the options and you can graph captured traffic by endpoint IP, mac or by protocol, as well as top talkers. There are loads of tutorials freely available.

    Wireshark has an impact on the network performance so it is best to choose a time when everyone is online and grab short captures - <5 minutes at intervals over a peak traffic hour. Don't leave it running indefinitely as the capture files get huge.
