Hi, I have been using my Laptop as WiFi Hotspot, but then suddenly we cannot access the internet through phones for some reason. We can connect to the hotspot I have created (shows it is connected), but could never access the internet. I know how to create a hotspot using cmd: netsh wlan start hostednetwork, like i usually do.. how come we cannot access the internet anymore, but my PC has an access? Please help..

Hi MicroFarad001,

"Hi, I have been using my Laptop as WiFi Hotspot, but then suddenly we cannot access the internet through phones for some reason."
Do you mean the WiFi Hotspot worked before (If it didn`t work before ,please refer to the following link to configure it)? Can we surfer the Internet from the Windows 8.1 machine ?Have you tried to connect to the WiFi Hotspot from another phone device to verify whether the issue is related to the specific phone device ?

Please check the "Allow other network users to connect through this computer's Internet connection" option and ensure it has been confiured for the virtual network adapter .
Here is a link for reference of creating the WiFi Hotspot in Windows 8.1 machine :

If the Windows 8.1 machine cannot surfer the Internet. Please take the following steps to have a troubleshoot :
1.Update the network adapter driver or reinstall the driver
2.Run the  built-in troubleshoot tool to have a diagnostic :
Control Panel\All Control Panel Items\Troubleshooting\All Categories\Network Adapter

We can also try the following steps to have a check .
1.Turn off the firewall and the antivirus software temporarily to have a check
2.Turn off the "Allow the computer to turn off this device to save power" option for your wifi adapter .(WiFi adapter -> Properties -> Configure -> Power Management -> uncheck "Allow the computer to turn off this device to save power")
3.Try to run ipconfig /release then ipconfig /renew (both no quotes), check if it can make any difference.

If it is possible ,we can create a new wifi hotspot to have a check .
