This part of the press release seems pretty crucial:
> Producers of consumer-grade routers that receive Conditional Approval from DoW or DHS can continue to receive FCC equipment authorizations.
In other words, foreign-made consumer routers are banned by default. But if you are a manufacturer, you can apply to get unbanned ("Conditional Approval").
In the FAQ (https://www.fcc.gov/faqs-recent-updates-fcc-covered-list-reg...), they even include guidance on how to apply: https://www.fcc.gov/sites/default/files/Guidance-for-Conditi...
If you (a manufacturer) apply, they want information regarding corporate location, jursidiction, and ownership. They want a bill of materials with country of origin and a justification for why any foreign-sourced components can't be domestic. They want information about who provides software and updates. And they want to hear your plan to increase US domestic manufacturing and progress toward that goal.
So, foreign-made consumer routers can still be sold, but they are going to look at them with a fine-tooth comb, and they are going to use FCC approval as leverage to try to increase domestic manufacturing.
