Internet crashes after browser opening, new tab opens etc. (Random)

Hello
The problem is it SEEMS that whenever a browser is opened, a new tab is opened (randomly) it cuts the internet off. What I mean by that is the router/modem still is working, has a signal etc. but ALL access to internet (wifi AND wired) are just stopped/blocked for EVERYONE. It is caused by just ONE computer. Once that happens - we have to reboot the modem/router - and internet is restored for everyone...UNTIL the one computer decides to do it all over again. That said - sometimes i can get 20 minutes of working internet on it - and then it decides to do it. OR after no use - and then simply opening a new browser, it will do it. Reboot router/modem again - and we are good (including the computer that causes the issue DOES get internet for SOME time). So it's not NO internet ALL the time.

I've uninstalled the anti-virus, tried different browsers, even tried WIRELESS instead of a wired connection and it STILL didn't it over the wireless connection - showing me that it DEFINITELY is on THAT computer. Even got a BRAND new router/modem from Century Link! So I have NO idea what to do.

(Also - I looked at the event log - and noticed errors - each error was time stamped with the time that the internet would go out. The error log # was 10016 - so I looked that up and deleted a few thigns from the reg edit (which would be replaced once system was rebooted). Did that - and issue still is there. I felt it was important to mention this in case it can help.

My sense is that there is an IP address conflict somewhere - maybe a static IP on the offending computer or some other misconfiguration causing the network's devices to become confused.

On the "one computer: what browser and OS are you using?

Are you able to run and review the results of "ipconfig /all" (without quotes) via the command prompt? Do so on the computer and compare the results to other working computers on the network.

Please post the results within this thread. Someone may spot something astray.

Ensure that only one network adapter is enabled on the problem computer.

Look into "ipconfig /flushdns". Reference link:

Check the Hosts file. May find something there.

You have looked at Event viewer as I understand your post - good.

Also try looking at the Reliability Monitor on the computer in question.

In the "Type here to search" block type "Reliability History".

Chose " View reliability history" when the menu option presents.

The Reliability Monitor screen will appear and you will see dates and colored error icons. Check the details by clicking dates and icons.

You may find more information about what is happening.

Also. Sketch out your network and show all devices wired and wireless and the connections between them.

Pay attention to the ports being used on the modem and router (modem/router). Check the ports' configurations. Some router ports are configurable: WAN or LAN. The computer should be connected to a LAN port

Any wall outlets, powerline adapters, switches? The physical connections should be checked. No loops.
