Thanks, editing the trusted zone did it. My previous router used 192.168.0.1 range and the new one 192.168.1.0 onwards

Hi, Win 7 SP1 64 Bit with Smart Security 7 Installed a new router and since then I can't see other PCs on my home network. If I temporarily disable the firewall I see them so problem looks like a Smart Security setup problem. Learning mode doesn't help. Network Discovery is on and sharing Public folders enabled on all PCs. Have searched thru setup, but none of the options and screens shouts "adjust me to fix your firewall problem" and I'm loathe to randomly change settings. Many thanks
