I just sent a email about not being able to scan Cisco 3845 routers with SNMP but I think I figured out the problem with it.
I looked in whats up gold and noticed the its using SNMP v3 and lansweeper is using v1/v2.
If I use device tester it is showing this
Pinging 172.17.246.253
Ping ok.

Any plans on adding support SNMP v3?
