I have installed Comodo Firewall (not Anti virus) v4.1.150349.920
On installation Comodo found my home network 192.168.1.100/255.255.255.0
I named this network but made my PC not accessible to other PC’s on the network. Also no tick in box for “Do not automatically detect new networks”
Now whenever PC is booted up Comodo finds a new network 169.254.160.75/255.255.0.0
Comodo states that this is a private network.
As I do not recognise this network I simply close the box. However, it is an annoyance.
Getting an IP address in the 169 range often means the connection is not working. Likely causes could be a faulty wire, faulty NIC, problem with NIC driver (that also includes returning from Sleep or hibernate mode).
