With regards to your disconnection problem I would consider it likely to be a problem either with your router/modem or your ISP. If your ISP supplied the router then take the whole problem up with them. If the router is yours then I suggest trying a different one - perhaps borrow one - to see if that clears the problem. If it doesn't, then it is a connection problem and that is firmly in the hands of your ISP.
For Comodo, I would suggest that you fully uninstall it and then re-install it, if you wish to carry on using it. Otherwise i would suggest fully uninstalling it and then using the built in Windows firewall which is perfectly effective.
Finally, you 'bumped' this topic two hours after your first post. This is a ridiculously short period of time considering that this is an international forum with a world wide membership. You have to give people time to even see your post. I used to route through the former Yugoslavia when I was a haulage driver and it would take me between three and four days to get from Scotland to Bosnia-Herzegovina ! It is fair enough to 'bump' a topic after three or four days without a reply, but not as quickly as you did.
