Wi-Fi Booster 7 x Connect app

What you’re running into is unfortunately a known limitation, not something you’re doing wrong. Wi-Fi Booster 7 does not currently appear in the TELUS My Wi-Fi / MyConnect app. Because of that, Booster 7 can’t be added via QR code or manual discovery, which is why the app keeps failing to find it. Booster 6 and Booster 7 are not mesh-compatible together. They can’t form a single mesh network, which explains why your Booster 6 shows a red light and no connection when paired with the Booster 7. The Booster 7 works fine on its own (solid green = good), but you can’t extend it using a Booster 6. If you need mesh coverage upstairs, you’ll need an additional Wi-Fi Booster 7 instead of reusing the Booster 6.
