Did you remove KL1 Kaspersky anti-hacker control driver?
please try to restore the original tcpip.sys then launch sigverif.exe
and let it scan for unsigned drivers.
Please check your firewall forwarding rules or test it in DMZ mode (only use this mode for few minutes as your pc will become directly accessible from the net)Setting Up A Default DMZ Server
The Default DMZ Server feature is helpful when using some online games and videoconferencing
applications that are incompatible with NAT. The router is programmed to recognize some of these
applications and to work properly with them, but there are other applications that may not function
well. In some cases, one local computer can run the application properly if that computer’s IP
address is entered as the Default DMZ Server.
Incoming traffic from the Internet is normally discarded by the router unless the traffic is a
response to one of your local computers or a service that you have configured in the Ports menu.
Instead of discarding this traffic, you can have it forwarded to one computer on your network. This
computer is called the Default DMZ Server.How to Configure a Default DMZ Server
To assign a computer or server to be a Default DMZ server, follow these steps:
1. Log in to the router at its default LAN address of http://192.168.0.1/
with its default User Name
of admin, default password of password, or using whatever Password and LAN address you
have chosen for the router.
2. From the Main Menu, under Advanced, click the WAN Setup link
3. Select the Default DMZ Server check box.
4. Type the IP address for that server (your PC fixed LAN IP).
5. Click Apply to save your changes.
