Dear Lifehacker, Ever since I bought my laptop there has always been trouble connecting to my home Wi-Fi. If the computer goes to sleep (set to 30 minutes of inactivity), then when it wakes up, the Wi-Fi won’t reconnect. The only way to get it working is to reboot the computer entirely. My siblings also have laptops on the same Wi-Fi, but there's work fine, so I think it must be my machine. Right now I have to reboot a few times a day - could this harm my laptop, and how do I fix it?
Yours is not an uncommon problem, and there can be a number of things causing it. Fortunately, it (should be) a relatively easy fix.
And don’t stress, rebooting your computer frequently doesn’t cause any problems.
The exact procedure will depend on what versions of Windows you are running, but in general it is all the same.
The problem appears to be that your computer is turning your Wi-Fi off during sleep, but not back on when it wakes up. You PC will turn it off to save power, but it sounds like some sort of bug is stopping it coming back on when it should.
It’s easy to check. Navigate to the Control Panel, and then Device Manager (or just type Device Manager into the Windows search bar).
From there, scroll down till you find the ‘Network Adapters’ and click to open it. You should then see an entry for your Wi-Fi device - ours says ‘Intel Dual Band Wireless-AC', but yours may be different.
Right click on the Wi-Fi device and select properties. From there open up the Power Management tab.
Make sure that the option for the computer to turn off the Wi-Fi is NOT selected. From there, reboot and see if that solves the issue.
Alternatively, some users report that they need to have the option selected (if not already) for it to work correctly. Try changing it, rebooting, then changing it back.
Alternatively, there might be a setting buried in your computer's power plan.
Head to the Control Panel, then open up Power Management. Typing ‘Power Options’ into the windows search bar works too.
From there, dive into the Advanced Settings, then Wireless Adaptor Settings. Make sure it's set to maximum performance.
Wi-Fi issues can be very frustrating, and there isn’t always a clear reason for the issue.
