Universal drivers may see compatibility issues with some wireless network cards.
If you use the built-in Microsoft Wi-Fi (WLAN) driver, we strongly recommend that you install the manufacturer’s “native” driver.
In our example the older version of the driver is Broadcom 802.11n Adapter version: 5.100.245.200 (the newer one has the index 6.30.223.102). Then find Broadcom in the list, choose the older version of the driver and press Next (the less number corresponds to the older driver version). In this window, click Browse my computer for driver software.
In Windows 10, as in Windows 8.1, TCP RWIN Auto-Tuning was preserved and sometimes the TCP autotuning means conflict with the settings of network equipment or firewalls (it doesn’t support or prohibit TCP Window scaling) causing package loss and the speed of the local network or the Internet decreases or even the completely access lost. But in practice, autotuning of the Receive Window (RWIN) size results in many network issues. In theory, this one should improve the efficiency of using network bandwidth and optimize the performance of the network subsystem. In Windows Vista / Windows Server 2008 a new feature, TCP Receive Window Auto-Tuning, was introduced to dynamically resize the size of the acceptor’s memory buffer (due to this feature, the maximum size of the transfer window can be increased to 16MB). Open the properties of the wireless connection and press the Configure button.Īfter the command has been run, restart the system, connect to the Wi-Fi access point and try to access the Internet. Check if this mode is enabled in the wireless device settings. It makes Windows automatically turn off the Wi-Fi adapter if it is not used for some time to save power. Disable Power Save Mode of the Wi-Fi AdapterĪnother possible reason of Win 10/8.1 to lose the connection to the Wi-Fi access point is the incorrect settings of the Power Save Mode of your Wi-Fi adapter. Netsh wlan delete profile name=Īfter you have deleted the profile, try to connect to the access point again and specify the password.
Try to delete the saved Wi-Fi network profile (as described in the post: How to Delete a Wi-Fi Network Profile). Your computer is trying to connect to the access point with old settings stored in the Windows wireless network profile. Perhaps the problem is that on the Wi-Fi router, the settings and / or the WEP/WPA2 key have simply been changed.
Apparently, the actual root of the problem is unusual behavior of modern Windows systems when working in safe mode. This issue has already been widely discussed, and there are some good, yet not very effective suggestions proposed by various users. Does the symptom sound familiar? If so, chances are that you’ll find this how-to useful. Most of the services you need are off and you’re having a hard time restoring your internet access. You reboot your Windows 10 or 8 machine into Safe Mode, and that’s where the big disappointment comes – you realize that for some strange reason the Wi-Fi connection is disabled.
