How to locate infected computer with a UTM5 or UTM10

I have worked with a number of Firewalls over the years, but the Netgear UTM Series Firewalls are not easy to work with.  After several attempts to find what computer is trying to access an infected web site I made a printout so I could easily find my way there.

Select "Content Filter" set the date back one day and select "Download" to get a copy of the data. It opens with a spreadsheet and then you can look in there to see who the offending computer is.

Comparing Digital TV Antennas

I have tried two different antennas for Digital TV reception. One cost me only $2 at a yard sale. One was far superior in rejecting interference and in reducing the number of drop outs.

Would you believe that the older antenna in the bottom picture did a much better job of rejecting interference like that of a train going by and in reducing dropouts? The four "bow tie" design is by far the best antenna for modern digital TV reception. The other antenna designs like the one in the top picture feature VHF reception and that is only needed for FM radio these days. The older bow tie type of antennas are also not nearly as directional so you usually do not even need an antenna rotor to get a good picture. So save yourself some money and get one of the old antennas!
