I have been struggling with this Comodo Firewall and I wanted to ask if someone here could help me to find the problem area which I have not found. I am 100% positive my issue is being caused by Comodo. Here is what I have found:
I can use the internet for varying periods of time and then suddenly the connection will drop. It will then say “Limited or no connectivity.” When I disable and then enable the LAN connection, it gets stuck at “Acquiring network address.” There are two ways I have found to get around this.
The first way is to reset the computer. This initially led me to believe that perhaps I had the WinXPSP2 network bug, so I d/led and installed that fix. No change. Then, I thought perhaps I had an LSP problem or a Winsock issue. I checked everything, and it is just fine.
So, I started looking to see if Comodo was the issue. Indeed it is! When I am at the “Acquiring network address” stage, I can sit there for ten minutes without change. But, if I right click on the Comodo icon and go to Adjust Security Level… Allow All, the connection works immediately. If I leave it on Allow All, I do not run into the limited or no connectivity problem.
Obviously, I do not want to allow all for the whole time I am connected, as having a firewall at that point would be pointless. But, I do not have issues with Comodo disabled, and I have the same issue repeatedly with it enabled.
Here are the essentials of my system:
Windows XP SP2 latest updates except Windows Genuine Advantage
Avast 4.7 (disable during all aforementioned tests, so not a contributing factor)
Comodo 18.104.22.168 CADV 3.0
Connected through Comcast using their combined cable modem/voip box… no router, just direct connection
Any help or suggestions are appreciated.
