Any visible wifi network is bound to get attacks and WPA/2 crack attacks, which is an attack vector into your home or office network. Especially since OpenWRT is set up by default as an access point, which forwards traffic to the wwan network, i.e. your main network.
I've set up firewall rules for the VLAN my iot devices are on, but still, less than optimal.
Would you rather have an extra door or a solid wall in your bank vault?

In that I respectfully disagree, as it is a default value for only 5% of the world's population. Furthermore, it is only documented for people well versed in OpenWRT setups, which is not the target audience of this 'user friendly' device, and the feature is completely undocumented on Onion's website. So I would call that a defect.
If they spent 10% of the money on the beautiful packaging on proper testing, we might not have had this issue.
Just my $0.02 opinion.
Also just installed haveged, thanks, but I don't know if the better random generator will help here.
