Internet not working with firewall ON

Comodo Internet Security - CIS Install / Setup / Configuration Help - CIS
#1

Hello, I have been using COMODO for the past 1 year and it has always satisfied me to the best.
I recently changed my service provider and they gave me a new Dongle to connect to internet.
Installed the device and tried to connect but I was not able to browse though I am being assigned the IP from them.
After a while I found a solution to the issue, I uninstalled the comodo firewall driver from the connection properties by going through network connection in control panel and I was able to connect to internet now.

Is there any work around for me to work on my new connection and firewall still on?
The new connection is kinda twice the speed as my old, so I should really need this to work to enjoy the new connection.
Thanks in advance for any help. :slight_smile:

CIS really should be able to work. Please try reinstalling (and running the cited removal tools) CIS by following the advice I give in this topic. Also, be sure to make sure that after removing CIS, and running the removal tools, that the Comodo drivers are also installed. Also, after reinstalling do not make any changes to the configuration or import any old rules/configurations.

Let me know if after reinstalling you are able to connect to the internet.

Thank you.

Thanks Chiron, that fixed my issue. Never thought this would work :>
Afterall restart and reinstall are still the universal solutions :smiley:
Though wondering why it did not work with my new dongle O_O

Re-installing by following the instructions in my guide often does work. The reason is that a normal uninstall, of almost any program, will still leave some files, or registry keys, on the system. Usually these do not cause a problem, but with a complex program like CIS this can cause issues, as you sadly encountered.

I believe what likely occurred is that something was left on the system which was configured for the older hardware, and thus did not work correctly with the newer one. Thus, ensuring that all old files are removed allowed CIS to correctly configure itself with the hardware. At least that’s what I think likely happened.

Thanks.
