Thank you very much for your report in standard format, with all information supplied. The care you have taken is much appreciated by Comodo, and will increase the likelihood that this bug can be fixed.
Developers may or may or may not communicate with you in the forum or by PM/IM, depending on time availability and need. Because you have supplied complete information they may be able to replicate and fix the bug without doing so.
For now I’m back to v5.12.256249.2599 (which seems to be working OK). Something to note: Changing to Comodo Secure DNS with either v6.0 or v5.12 also disables my Internet connection. I have to have my DNS set to “Obtain One Automatically”.
Wouldn’t disabling the firewall be effective? I tried that, but the problem persisted. I also tried a default install without touching any settings. As soon as CIS was installed, the Net connection was lost.
Just a stab in the dark.
I do not suppose an old FW driver is being left behind, causing two drivers trying to be active and conflicting with each other.
Check to be sure only one is present in Widows Device Manager.
See Eric’s post here.
Just for more info - how did you install 2708? Clean install, uninstall 2674 → then installed 2708, ‘updated’ 2674 to 2708 via downloaded installer package or through 2674’s check for updates (internal program)?
I have HDD trays for swapping operating systems. The program works on WinXP and blocks the connection on Win7. Both drives are mounted in the same machine. Same Ethernet card. Same drivers (which are up-to-date). Note that 5.12 works fine with Win7 and my current Ethernet card.
On my first try, it was a fresh install of Win7 and a fresh install of CIS 6.0 (no left over drivers). On this next clean install, I made sure the drivers were uninstalled before installing this new version.
Totally uninstalled 5.12 with Revo. Deleted all left over directories. Made sure the drivers were uninstalled. Did a clean install from cispremium_installer.exe. As soon as CIS is installed, the Internet connection is lost. Disabling the Comodo Firewall Driver returns the connection.
Out of interest, is there any connectivity or is it just the Internet. Are there any alerts of any kind post installation of CIS. Also are there any errors in the Windows System log?
I had something similar to this earlier today, when putting the new version on a test box. Basically, after installation and reboot, I had no connectivity at all. What I had to do, three times, is disable and re-enable the network adapter. Finally, after about 5 minutes it connected. It’s not the first time I’ve seen this but this was the longest it’s taken to become active.
Thanks for the update. Just to see further, is there any ‘caution’ (yellow triangle) items in the Device Manager when Comodo Firewall Driver is active? (You may have to reboot with the firewall driver active to see what is conflicting.)
