Walk through any Best Buy this month and you'll see them stacked near the registers: glossy boxes promising "WiFi 7" speeds, "multi-link operation," and "seamless whole-home coverage." The pitch is irresistible.
Your kids complain about lag during Fortnite.
So you buy the $399 unit, take it home, and plug in a device that now watches every packet your family sends.
Here's what almost nobody explains at checkout.
A modern router isn't a dumb pipe anymore.
It's a computer with a persistent internet connection, a microphone in some models, and a business model.
Companies like TP-Link, Netgear, and Amazon's Eero have quietly moved toward subscription tiers, cloud-based parental controls, and "security scanning" that routes your traffic through their servers.
The hardware is cheap because the data is valuable.
The WiFi 7 upgrade cycle makes this worse, not better.

You can't vote with your wallet when there are four manufacturers and they all do the same thing.
Buy the WiFi 7 router if your devices support it and your old one is genuinely failing, but do three things first.
Change the default admin password before you connect it to the internet.
Turn off cloud-based "smart" features unless you specifically need them.
And check whether the manufacturer sells a subscription, because that tells you where their incentives live.
It's just basic hygiene that the industry has spent a decade making inconvenient.
The uncomfortable truth is that we're trading privacy for convenience at a scale our parents never imagined, and we're doing it one Black Friday deal at a time.
Your router knows when your lights go off, when your teenager sneaks downstairs, and what your spouse searches at 2 a.m.
Final Thoughts
Buy the router, but read the terms, change the password, and remember that "smart home" has always meant someone else is doing the thinking.
