I have had an issue off and on with the Z100G not completing file downloads. Doesnt seem to matter if its an http or ftp download and it happens on every PC on the network. It will get 4 or 5 MB into the file and then hang. The download can usually be restarted, but ususally fails again (sometimes even after less than a MB) only to repeat the cylce over and over until I can get the whole file. I was trying to download open office today and just gave up. Way too much work with over 140 MB file.

I have high security and rules set to allow the needed traffic. My firmware is 8.0.39x, but the issue has happened off and on for over a year, so I guess it could be firmware related. I do have the service center, 15 node upgrade, and antivirus enabled.

Anyone have any ideas or similar experience?

What happens if you turn off the antivirus?
Try to look at the Memory/CPU % under the reports menu when you download a file.

Turned off antivirus and issue is still present. Memory and CPU stayed consistent during the download I was trying.


I turned AV back on and tried another download. FW Memory went up slightly, but CPU shot up into the 30%-50% range. I also noticed that when the download would hang that CPU would drop to almost nothing.

Thought these results were curious so I turned AV back off again. This time I saw different results. Not really sure what to think now.

By the way it looks I don't think its the Antivirus that is causing the issue.
I think it will be best to debug it online with SofaWare's support.

Did you find a solution to this? I have the same problem.

This is a known issue and Sofaware is working on it. I am not crazy about the work around, but it is better than stalled downloads.


Please try the following

At security , smartdefense
Run the wizard
Set it to minimal
Check none of the options and see if that helps ?


As an alternative, you can try this Smart Defense setting first to see if it helps:

At smartdefense , instant messaging ICq
Set the Block masquerading over HTTP protocol to None



I manage an enterprise Checkpoint firewall at my work and I have experienced this as well. The Smart Defense rule that triggered it was:

Attack: Content Protection Violation
Attack Information: Malformed RPT file detected (MS07-052)


Good luck!

Any news on this.

I am at minimal settings and ICQ is all set to none.

I am unable to complete a large download for some time now. I just plugged a notebook directly into my FIOS router and download 600mb ISO in a couple of minutes on the first try. Plugged the same notebook into the firewall and it failed again.

Speeds when plugged directly into the FIOS router where 3 time faster then when plugged into the firewall (until it fails).

I also experienced connection strangeness when downloading large files, or even e-mail and had frequent dropped calls on my VoIP phone. I did a check online of my connection statistics through the Z100G router and got a very low Quality of Service score in the 10-20% range. When I bypassed the router and connected straight into the phone company's router, I got a reading in the high 90% range. I replaced my Z100G with a LinkSys and get in the high 90's on quality. I like the features of the Z100G, but I need quality, stable connections.

You should contact Sofaware support for a fix.

Thanks, the alternative solved the problem for me.
