They clearly have many weapons still understood, along with machines of various sorts, even if prohibitively expensive. They were even able to innovate designs with the Sveagen saw-trains.
You need to keep in mind that many of today's amenities we take for granted require layers upon layers of infrastructure, supply chains, resources, and given that Old World cities as a general rule are lost, along with the stuff they had, you have to work to keep your society supplied with what resources you can jerry rig back together. Like much of Iceland's population centers being abandoned due to famine despite no big time Rash outbreaks on the island, leading to ruralization. If high tech automation is a bust, things become more labor intensive, but there just aren't enough people to do these things because they're already preoccupied with feeding themselves and defending against the infected. Even Mora, arguably the most technologically advanced city in the nordic region, only fairly recently built up the necessary shit to have telephones for individual houses
For the vast majority of the known world, anything that doesn't contribute directly towards keeping your people from starving or being overrun by trolls is a can to kick down the road
