Hi. I've decided to connect two computers with an Ethernet cable to share one network (wireless USB modem). The host computer runs Windows XP, the client - Windows 7 Ultimate. I've allowed sharing in the wireless network settings and the first time it worked (I believe that means I have the right type of cable etc.). The next time I turned the computers it wasn't working (on the client computer) except for Skype - it was working with no problem. I tried to use various guides to change the settings of my connection (manually add IP addresses etc.) still nothing, I had to restore both machines to an earlier point... Then on the host (XP) computer avast broke down, the protection was off and I wasn't able to turn it on, I had to use the avast uninstaller through Safe Mode and then I reinstalled it, then I connected both computers - voila - internet works on both of them. I reboot - only Skype works on the client computer.
This now leads me to believe that avast is blocking full sharing. All the guides to troubleshoot this issue use the firewall settings, which I'm unable to find in my free version. What do I do? Where in avast do I check the box for it to allow ICS?
