How not to lose Wifi after waking up from standby or sleep mode?
I cannot believe this, but after months of trying to fix this, it turns out that, for me, checking ON (enabled) the "Allow the computer to turn off this device to save power” worked.
Got this idea from Intel’s My WiFi Technology stops working after resuming from sleep or hibernate in Windows 7. My guess is that the driver expects to turn the network card back on after sleep or on a cold boot, and because the option is turned off, it toggles the "switch" from being already on to off. Maybe?
Anyway it works for me now, perfectly.
Apparently, disabling a Windows power saving option causes a family of Intel drivers to malfunction. I was able to solve this issue on two Intel network card-equipped Lenovo ThinkPads. So if your computer also relies on an Intel WiFi network card, I'd suggest you :
- Go to the
Windows Control Panel - Click on
System - Select the
Device Manager - Right-click on your Intel wireless device and choose
Properties - In the tab Power Management, enable the option
Allow the computer to turn off the device to save power.
This solved my problem. As I am not using an English version of Windows, let me know if you can't find those menus.
For me on an HP EliteBook Folio 9480m (Windows 7 x64 SP1 with an Intel Wifi chip), the solution was to switch "Allow the computer to turn off this device to save power" OFF, and then back ON. Unbelievable!
