The part nobody's talking about is that this ban traces back to Section 889 of the 2019 NDAA, which already blocked Huawei and ZTE from federal procurement. The FCC is just extending that logic downstream to consumer gear. TP-Link is the new target because they hold something like 65% of the US home router market and they're headquartered in Shenzhen.

For anyone running a Bitcoin or Lightning node at home, this matters more than it looks. TP-Link Archer routers are probably the single most common device sitting between home nodes and the internet. They're cheap, reliable, and the C7/AX series run OpenWrt beautifully. If those get pulled from shelves, the next-cheapest OpenWrt-compatible option jumps from $30 to $80+.

The saving grace is that the ban targets new sales, not existing hardware. Your current router keeps working. And flashing OpenWrt onto it actually helps the security argument since you're replacing the manufacturer firmware that was the concern in the first place. The irony is that open source firmware on "banned" hardware is probably more secure than stock firmware on "approved" hardware, but the ban doesn't distinguish between the two.
