First check cellular data on the phone
Switch Wi-Fi off on the phone, leaving mobile data on, and open two websites. If the phone itself has no mobile internet, it cannot share that connection with the laptop. Check signal strength, a data limit and any carrier outage. Some plans restrict tethering, so read your provider's current terms. A hotspot that is invisible to the laptop is a different problem from a hotspot that appears and connects but has no internet; knowing which symptom occurs avoids unnecessary changes.
Check hotspot name, password and permissions
On Android use Settings or Quick Settings to enable Wi-Fi hotspot under Hotspot and tethering; names vary by manufacturer. On iPhone open Settings → Personal Hotspot → Allow Others to Join, if your carrier supports the feature. Look at the exact network name and case-sensitive password, then connect to that network on the laptop. If Windows saved an old password, forget the saved network and enter it again. Keep the devices nearby during testing and make sure the phone has enough battery.
Try the compatibility band when the network is invisible
A laptop may not support every wireless frequency or hotspot security mode. Many Android phones let you choose a 2.4 GHz band instead of 5 GHz. On supported iPhones, Maximize Compatibility can help some older devices, but Apple warns it can reduce security or performance. Change only the relevant setting and test again. Keep a strong password with a supported protected security mode; do not remove hotspot security to force a connection. Note which band successfully works for future travel.
Test Windows without removing drivers immediately
Toggle Wi-Fi off and back on in Windows, restart the laptop and phone, and verify you have chosen the right hotspot. If the laptop joins ordinary home Wi-Fi but cannot find the phone's network, prioritize band and phone hotspot settings. If no Wi-Fi networks appear at all, run the Windows network troubleshooter and look at the adapter. Windows 11 offers Get Help diagnostics. Avoid factory-resetting your home router, because it does not control the phone hotspot and resetting it could disconnect everyone.
Connected to hotspot but still offline?
Try opening a website through cellular data on the phone with its own Wi-Fi disabled. Check for an exhausted tethering allowance, a roaming restriction, VPN configuration or battery saver that may interfere on that specific device. Some hotspots automatically shut down when idle or limit the number of clients. Test a second laptop or tablet if available. If every connected device is offline while mobile internet works on the phone, consult the mobile operator and the phone manufacturer's guidance rather than reinstalling laptop software.
Consider USB tethering and protect your data plan
Most Android phones can share mobile data with a Windows computer through USB tethering if you use a data-capable cable and your plan permits it. An iPhone may have additional platform-specific requirements. Hotspot use can drain the battery and use large quantities of data during Windows updates or cloud synchronization. Turn the hotspot off when no longer needed and avoid sharing its password with strangers. Related guides: /guides/wifi-connected-no-internet-windows/ and /guides/wifi-router-placement/.
