So to fix this you should: Open Settings -> Firewall (Settings) → Application (network) rules. Search for Firefox/Chrome/Edge, etc… Double click on Firefox/Chrome/Edge, etc… Go to tab Exclusions. Make sure you choose check and chose "Do not scan all traffic” in the drop-down. Check the option "Only for specified IP addresses". Enter the IP address of your router. Save.Note: The text shown in parenthesis is only shown when you are on that page, it is not shown on the menu entry. It is a workaround but until a more permanent fix can be found this will get your modem access working. This should work for both Kaspersky Internet Security and Kaspersky Total Security.

Hi! What worked for me for this problem was to do what is described here (see answer): Link but for all traffic, not just encrypted traffic. It is a pain since you have to do it on a per application/browser basis but at least this workaround actually works… Whitelisting in the web anti-virus and firewall and changing the TCP and UDP traffic allowed as suggested by support does not work for this problem.
