Work through these checks in order
If several devices drop at the same time, focus on the router, modem or internet service before changing one device.
A short test near the router helps separate weak coverage from other causes.
Turn Wi‑Fi off and back on, reconnect to the network and restart the router only if it is safe to do so.
Install normal system/router updates and consider congestion from nearby networks or electronics.
Full network resets erase saved connections and settings. Use them only after simpler checks and only if you understand what will be removed.
Before an erase, restore or repair decision
Confirm what data is backed up, what a reset or restore will remove, and whether you still need access to account credentials or authentication methods stored on the device.
When professional service makes sense
Hardware damage, repeated power failure, liquid exposure, battery swelling, damaged ports, broken displays and problems that persist after low-risk software checks can require qualified inspection.
