No internet or Wi-Fi keeps dropping

Try these steps

1. 1 Check whether other devices (a colleague's laptop or your phone on the office Wi-Fi) have internet. If nobody has internet, the problem is the office connection, not your computer.
2. 2 Turn Wi-Fi off and on again on your computer (click the network icon in the taskbar, switch Wi-Fi off, wait 10 seconds, switch it on).
3. 3 Forget the Wi-Fi network and reconnect: Settings → Network & internet → Wi-Fi → Manage known networks → select the office network → Forget, then connect again with the Wi-Fi password provided by your office.
4. 4 If you use a cable, unplug the network cable from the computer and plug it back in firmly until it clicks. Check that the small light next to the port blinks.
5. 5 Restart your computer (Start → Power → Restart), not just shut the lid.
6. 6 Move closer to the Wi-Fi access point and check whether the connection becomes stable — weak signal in one room points to coverage, not your device.
