Samer saw your post, and brought it to my attention that the firmware code does not handle netmasks other than 255.255.255.0. Are you using DHCP or static IP? I know for sure that the static IP option does not give you a way to modify netmasks, which is very likely the cause of the issue you’ve seen. However, I assume the DHCP library we are using should handle that automatically. Do you know if your office network use a netmask other than 255.255.255.0?
