Cannot Hold Internet Connection Longer Than 30 Seconds

[Badeumus]

Hi guys my PC has been having serious internet connection issues since this afternoon. I cannot hold a connection longer than 30 seconds before it bricks itself. I run the troubleshooter and it fixes it, for 30 seconds, until it breaks again. When I run the troubleshooter I get the messages:

 

"The connection between your access point, router, or cable modem and the internet is broken" - Detected

"The default gateway is not available" - Fixed

 

Disabling and enabling the network adapter instantly fixes the problem for 30 seconds as well. I have done a network reset, I have done a windows reinstall, I have tried manually setting the IP and DNS address. Additionally when it "fixes" itself IVp4 gets connected but IVp6 does not and is always disconnected. This is a new PC I built for myself back in February and my fear is that the motherboard ethernet port is bad from the factory (I noticed I don't always get status lights). New ethernet cable and new router too. Thanks and and yall are going to be definitely more helpful than windows support who said "your internet is broken contact your provider"

Do you have your drivers downloaded and up to date? Have you tried a different Ethernet cable?

 

I’m fairly certain if the motherboard doesn’t detect a cable it won’t display status lights. The drivers or cable would be what I’d investigate first.

Maybe the drivers, cable or router/switch

Hi there, can you please provide the make and model of your NIC and the router, as well as any other network devices that sit between your NIC and router (i.e. access points, repeaters, extenders, etc.) My immediate though is not usually to assume there is a network issue, however I do find it interesting that your default gateway was "not available" There may be a configuration error that can be rectified through the web interface. You can reach your router's web interface by typing [https://<default_gateaway_ipAddress>] into your browser, login credentials are usually found on the manufacturer's sticker on the bottom/ back of the device. I would first initiate a firmware update on your router, then poke around and see if there are any configuration options that might assist you in solving the problem. If you can provide me with the make and model, I can take a look at the documentation and try to help you sort through where to look in the web interface.

run sfc /scannow in an admin cmd window.. 

reinstall chipset and network drivers.

I have new cables that I bought and I have swapped them out still no dice. Drivers were updated less than a week ago and in the brief moment I have internet it says they are up to date.

Router get's a firmware update each night at 3am. Trying to access the web interface doesn't work. Router is a DECO x55 and what is a NIC?

A NIC is a Network Interface Card, in other words the Ethernet or Wi-Fi card you are using to connect to your home network. These Deco x55's have the ability to be configured as either Routers or Access Points, my personal preference with devices like these is Access Points, I find that I run into less problems this way and it in no way impacts speed or performance. You can change this setting in the Deco App. If this doesn't solve your issue, attempt accessing the web interface of your ISP router, not the Deco. From there you can follow the suggestions I made earlier.

Followed this and these settings fixed my issue. Wish I had done this before the factory reset ;/
