A tablet without internet is like a smartphone without a SIM card: it works, but loses half its functionality. Wi-Fi connection issues on tablets Samsung, Huawei, Lenovo or Apple iPad Problems occur more often than you might think: the network can't be found, the password isn't accepted, or the connection keeps dropping. In 80% of cases, the fault lies with the device, not the router—and they can be fixed on your own in 10-15 minutes.

This article covers everything from basic Wi-Fi setup on a new tablet to troubleshooting complex issues. We'll explain why The tablet doesn't see the network, connects but does not access the Internet, or Wi-Fi only works near the router.Separate instructions for Android (including Samsung One UI And MIUI) And iPadOS, as well as a table of Wi-Fi standards compatibility will help you choose the optimal router settings.

If you have already tried rebooting the device and the router, skip the first two sections and go straight to troubleshootingFor owners of older tablets (manufactured before 2018), a spoiler has been added detailing the nuances of supporting modern Wi-Fi 6 networks.
