TP-Link WiFi QR code
TP-Link currently documents a Share control in Tether and notes that some compatible models can display a QR code for WiFi sharing instead of only sending or copying the network details.
Treat model support as part of the answer. Use the Tether option when it exists and create a separate QR only when the required sharing asset is not available.
Change WiFi name or password after printing
No reprint needed.
Tether has a documented network-sharing flow
TP-Link's current guide uses More > WiFi-Settings > Share on compatible routers.
QR support is model-dependent
TP-Link explicitly notes that some models can share access with a QR code in Tether.
The exact app path can differ by product type
TP-Link's own examples use different Tether paths for a router and a range extender, so do not assume one menu applies to every device.
The useful part is knowing whether Tether already exposes the current network and how that particular product shares it.
Tether can expose the live WiFi sharing controls instead of relying on an old sticker or remembered password.
Check the supported feature on the actual router, mesh unit, or extender before following a screenshot from another model.

Workflow
Use the model's Tether workflow first and generate a separate asset only if the needed QR is not available.
On compatible routers, TP-Link documents More > WiFi-Settings > Share in Tether.
Some models offer a QR-based Share Wi-Fi option; others expose copy or messaging methods.
Confirm the intended main or guest network before creating any separate code.
Use a standalone QR when the app does not provide the persistent asset you need for placement or print.
The brand-specific value is choosing the correct current app flow for the actual model.
Use the current Tether sharing page and check the model's available share methods.
Expect different Tether menus and confirm whether the product exposes a Share Wi-Fi QR.
Use the current credentials from TP-Link, then create a separate tested asset only when the app QR is not enough.
Questions about Tether sharing and model-specific QR options.
Yes. TP-Link currently documents a network Share control in Tether for compatible products.
No. TP-Link says features can vary by model and notes that some models support QR-code sharing.
Router, extender, hardware version, region, and app support can differ. Use the current support page for the exact product.
Create one when the Tether workflow does not provide the reusable file or physical placement you need.
No. Verify the current WiFi details in TP-Link first, then enter them only if you need a separate fallback QR.
Yes. Generate a replacement from the new credentials and test the exact asset before redistributing it.
Verify the live Tether network details, create a separate WiFi QR, and test the exact asset before putting it in front of guests.
