How to fix problems with Atheros A6100?

Here are eight fixes you can try out.

Restart the router

As always, the first step in troubleshooting anything is to reboot the device that may be causing the issue.

It almost seems like a joke now, but rebooting your device does have some pretty surprising results, and you might be able to resolve many seemingly random issues.


Check your drivers

Your network adaptor’s (WiFi or ethernet) drivers could also be causing connectivity issues. Try connecting to the internet using either an ethernet connection or any other alternative and follow these steps to get your drivers in place.

Step 1: Press Windows key + R, type in devmgmt.msc and hit enter.

Restart the PC and give it another shot.


Check your DNS settings

If you’re running custom DNS settings on purpose or by mistake, having them set incorrectly can cause internet connectivity issues.

Flushing your DNS settings can set them back to the default values and resolve such issues. Here’s how. 

Step 1: Press Windows key + R, type cmd and hit the Enter key.

You can take this a step further and reset Windows files to access the internet by using these commands back to back.

netsh winsock reset
netsh int ip reset

If you suspect an issue with your router’s DHCP assignment, use these commands to release your old IP and request a new one. 

ipconfig /release
ipconfig /renew

If that doesn’t work either, you can use the following commands in the order that they’re listed to reset your network stack.

ipconfig/flushdns
nbtstat -R
nbtstat -RR
netsh int ip reset C:\resetlog.txt
netsh winsock reset

Check for IP /DNS conflicts

If you can connect to other networks just fine, it could indicate an IP conflict on your router. 

Another way to confirm this is to ping your router’s default address through the command prompt. Type in ping [router IP address] in the command prompt, and if you get a Request timed out error, you’re most probably having an IP conflict issue. Here’s how you can fix this.

Step 1: Press Windows key + I to open the Windows settings.

Now reconnect to your network, and it should connect seamlessly. Alternatively, you can type in your IP address and DNS alternatives to see if that solves the issue in Windows.


Reset your network settings

Step 1: Press Windows Key + I to open Windows Settings. Click on Update and Security.
