Is Home edition is compatible with wi fi system.
I got a router modem with WI FI .after loading the software and scan the initial section after rebooting I got the message " Protocol TCP/IP is not loaded".
Is there a firewall inside ?
Avast is anti-virus software, not a firewall.
If you have setup the WiFi correctly, Avast will work without a problem.
Do you have the TCP/IP protocol installed?
