The common solution is to install the latest drivers from the makers site for the motherboard and/or the network adapter.
The common work-around is to not use sleep, but try hibernate and if that doesn't work shutdown and reboot.
I don't think it's related to using the VPN. But it's worth a try to see if it makes a difference if you don't.
Same for Zonealarm.
hello, i have a problem.
i thought it was comodo but it isnt.
i use a vpn and now i am using zone alarm free firewall and avast free antivirus. but after i put my pc to sleep, and wake up again, i have no internet anymore. i thought deleting comodo would solve the problem but i thought wrong.
