Intermittent internet connection issues

Hello Trevor,

Thank you for posting your query on Microsoft community.

There are some reasons that causes this error connection reset. Let’s try to identify the root cause and apply the appropriate solution to fix this.

I suggest you to run the network troubleshooter first, and check if the issue persists. To run the troubleshooter, follow the below steps:

1. Press ‘Windows + X’ key.
   
2. Select ‘Control panel’
   
3. In the search box, type ‘Troubleshooter’ and then click ‘Troubleshooting’
   
4. Under ‘Network and Internet’ click on ‘Network adapter’ and click on ‘Next’ button.
   

Try to update the network adapter and check if the issue persists.

1. Press ‘Windows + X’ key.
   
2. Expand the network and adapter’
   
3. Right click on the device, and select ‘Update driver software’
   
4. Restart the computer and check.
   
5. You can also check for updates from the system manufacturer site.
   

Check proxy settings by doing the below steps:

1. Go to Control panel – Internet options.
   
2. Click on ‘Connections’ tab.
   
3. Click on ‘LAN settings’
   
4. Uncheck ‘Use a Proxy server for your LAN’ check box, and click ‘Ok’
   

I also suggest you to reset IP Address by following the below steps.

1. Press Windows key, and type ‘Command prompt’
   
2. Right click on it and select ‘Run as administrator’
   
3. Type the following command without quotes, and press enter: ‘netsh winsock reset catalog’
   
4. Restart the system once and check if the issue persists.
   

Try to disable Kaspersky firewall and check if that helps

1. Open the Kaspersky Internet Security program.
   
2. Click the ‘Settings’ button.
   
3. Click the ‘Firewall component’ option under Protection Center.
   
4. Select the ‘Enable Firewall’ option to remove the check mark.
   

Hope it helps. Please reach back if the issue persists.



Thanks and regards

No wifi /internet access after windows 10 upgrade a month ago

Check list; device manager, network adapters, power management, wake and sleep settings both lan and wifi.

Pc power options, wifi settings, maximum power, if usb adapter turn off usb selective state, if pcie set link state to

moderate or off.

On device manager, driver settings also check advanced tab, the device not being used set power settings to turn off the device.

Also check windows update options if wifi is set to share or metered connections.

If these steps do not work, it may be necessary to turn off the device not being used in the pc bios.

Windows will use a lan connection over a wifi connection, so if lan is connected it can cause problems, disconnect

the lan cable and reboot.

I have two pc's that use usb wifi adapters and I had to perform these steps each time win10 gets updated, so

you are not alone on these issues.

 

Asus P5Q Onboard Lan issues...

I've just reformated my pc, and it all runs fine except for the the onboard lan. I've tried every LAN driver on ASUS list, and I can't get it to work. It keeps searching for the connection, but it never finds it. The internet runs fine on my moms PC, so it can't be the internet provider*Frown Onboard LAN is enables in BIOS, and I did try to clear CMOS without any luck.
Any suggestions? It really sux.... I think the P5Q Pro is a buggy board...
