Method 1: Restart computerThis is an extremely common step for nearly any computer problem, and since the network issue may be tied up in your computer software, you should start with a reboot. You may have already tried this step, in which case you can move down to the next one.
Method 2: Reboot your router or modemNote: reboot, not reset. Rebooting is just powering it down and then turning it back on, while resetting the router means to restore all of its settings back to default – a step that’s a bit more destructive than what we’re after right now.
Method 3: Reset the Windows TCP/IPRun this command in an elevated Command Prompt (Window + R then type cmd -> Enter) to reset the Windows TCP/IP stack to its original state, a step that often fixes lots of network related issues:
netsh int ip reset C:\resetlog.txt
Method 4: Uncheck the option that lets the computer turn off the device to save power
If on Wi-Fi when you see this error, it’s possible that the network adapter is going to sleep to conserve power. You can stop this from happening in the Power Management tab of the adapter. Here’s how: Find the Network and Sharing Center in Control Panel. Right-click the Wi-Fi connection, go into Properties, then hit the Configure button, and find the Power Management tab. Uncheck the option that lets the computer turn off the device to save power.
Method 5: Set obtains an address automatically from the DHCP server
If your network is using DHCP, first find your local IP address. If the IP address is set to a static IP address, you need to change the adapter’s settings so that it obtains an address automatically from the DHCP server. Follow the directions here to find the DHCP settings in Windows, and make sure that DHCP ends up enabled and that there isn’t a specific IP address recorded for the adapter. If the local IP address your computer is using, starts with 169.254, it means it’s invalid and isn’t obtaining a useful address from the router. Try running the commands
ipconfig /renewin a Command Prompt.
Method 6: Set static IP address
If obtains an address automatically from the DHCP server were set, but error still can not fix, let set static IP address. In Wifi properties, double click on Internet Protocol Version 4 (TCP/IPv4) Select Use the following IP address, in IP address, type 192.168.1.x, where x is a number from 2 – 255. Select 255.255.255.0 In Subnet mask in Default gateway, type 192.168.1.1.
In Prefered DNS server and Alternate DNS server, type Google DNS: 184.108.40.206 and 220.127.116.11.
Method 7: Update the device driver for the network card
Try updating the device driver for the network card. An outdated card or corrupted driver might be the problem.
Method 8: Troubleshoot problems
If Windows prompts you to have it try to fix the connection itself itself, then agree to that and run the Network Troubleshooter or Network Repair utility (they’re called different names depending on your version of Windows). Right click on Wireless icon, select Troubleshoot problems.
Method 9: Disable WMM for Broadcomm WLAN
For Broadcom Wireless LAN, Open Device Manager, Select Network Adapters, double click Broadcom 802.11n Network Adapter, open Broadcom 802.11n Network Adapter Properties, Select Advanced tab, select WMM as shown in fig below, set WMM to Disabled, click OK.
Method 10: Contact the router manufacturer for additional support
If there’s still no connection, unplug your router and connect the computer directly to your modem. If this configuration works, and you no longer see the error, your router might be malfunctioning. Contact the router manufacturer for additional support. However, if the error remains and the network still appears to be down, contact your internet service provider for support – the problem may lie with them.
