Internet connection problem

I'm having some internet connection problems. My father installed a new router a couple days ago and since then, my internet has been going on and off. I use an ethernet 3 cable, plugged right into my computer from a switch in my room. That worked until he installed some wires to other parts of the house. When I put the cable from my computer into the internet it'll give me like 250 mbps. Now it's like 95 mbps, which is what it was before, but this time it's plugged directly into the main switch. I've heard getting half the mbps is normal with the switch? Or maybe that just happens with a router? The other devices get 250 mbps when tested.

So, here's the problem. Since I was still getting internet directly from the box, we plugged that cable into the switch. It didn't work. So we plugged it back into the main internet box. It didn't work. Plugged it back into the switch, rebooted my computer, troubleshooted my connection and now it's back to the wobbly on/off thing, with 95 mbps dwnld/25 mbps upload.

I don't know if this is a hardware issue or this is the switch box. When my old switch box stopped altogether, it was saying the DNS couldn't be configured. I flushed the DNS, rebooted, trouble shoot, nothing. All my dad was run new cables to other devices so I don't know how that could've killed my internet, which is why I'm leaning towards hardware.

Is there any way for me to tell? My processor is AMD Ryzen 7 5800X 8-Core Processor 3.80 GHz. My RAM is 64 GB. My send/reciever link speed.

    Hi, RWhit_588

    Thank you for your reply!   I noticed that you are using Nord VPN as well as Malwarebytes software. Through user feedback from another case I've dealt with before, Nord VPN can often cause network problems, so I would suggest that you can remove the Nord VPN as well as the Malwarebytes software as this is a third-party software that causes network problems.It is recommended that you reset the Hosts to see if the problem can be solved.Before performing this solution, it is recommended that you copy the hosts file to your desktop for backup and then try the steps in this link:How to reset the Hosts file back to the default - Microsoft Support

    It is also recommended that you contact Nord Support as well as your network provider.You are welcome to contact us at any time if you make any progress.

    Best Regards

    Hi, RWhit_588

    Welcome to Microsoft Community.

    We understand that after making some changes to your home network, you seem to be experiencing some problems with your Internet connection.  From your description, it seems that the issue is more related to the router and the switch, considering that you are experiencing the problem after replacing the router.It is suggested that you can try the following options first to rule out if it is a system issue:I. Reset the network1. Search for CMD, open and find the command prompt (, run in administrator) mode2. In the command box that pops up, enter the following commands (each line after the completion of the run enter the next one)ipconfig /releaseipconfig /renewipconfig /flushdnsipconfig /registerdnsnetsh int ip resetnetsh winsock resetnetsh winhttp reset proxy3. Restart the computer to see if the problem can be solved.Reset network settingsTap windows+R, type inetcpl.cpl, open Internet Options, click Advanced, and check “Use SSL 3.0” and “Use TLS 1.0”, “Use TLS 1.1”, ‘Use TLS 1.2’, reboot the computer after the application to see if the problem can be solved.Reset Proxy Server SettingsClick windows+R, type inetcpl.cpl, open Internet Options, click Connections, click LAN Settings, check whether the Proxy Server column is checked, if so, uncheck it and click OK, restart your computer after applying it to see if the problem can be solved.Change DNS1. Click windows+R and type ncpa.cpl.2. Click on the name of the network you are now connected to, open the Network Status window, click Properties, and then double-click Internet Protocol version 4 (TCP/IPv4) in the Network Properties window.3. Manually set the DNS servers to “4.2.2.1” and “4.2.2.2” and restart your computer to see if the problem is solved.If you are still experiencing network connection problems after trying the above solutions, then the problem is caused by your router or switch, we suggest that you contact your network provider and check if your network interface meets your network speed requirements.If you have any progress, please feel free to contact us.

    Best Regards

    Thank you. This worked. I did the host thing and uninstalled Malwarebytes. I then went back and did step 1 from your first reply, rebooted, and got a connection through my ethernet (100 mbps.) When I got up in the morning, it was out again. I troubleshooted and it said the IP wasn't configured right, but it apparently fix that. Tried again when I got home and internet was on, 250 mbps, everything all good.

    It's crazy that Malwarebytes could do that. Very happy! Thank you so much for your help. I was about to take it to a shop to see if it could be fix. LOL

    That helped somewhat. I did the steps and it kind of helped. Kinda sorta. There is no router, so there's no problem there. Also, the switch box is new. We tried to plug in the (new) ethernet wire to a different port and that didn't fix the problem. As I said before, when plugged right into the modem, I got about 250 mbps. My mother's computer is plugged into the switch and she gets 250 mbps. My dad's laptop is wireless and he gets 150 mbps. Basically, everything else in the house is fine.

    I should add that I bought a wifi USB and was able to connect to that absolutely fine (i have to disable the ethernet, though.) I don't have any of the problems I had trying to use the ethernet. However, it's slow. About 60 mbps. I bought my computer in 2021, so it's not old. The rest of the computers are significantly less then my own. I don't download a whole lot. Mostly steam games. I went through and uninstalled them all. I also had Nord VPN and Malwarebytes. I uninstalled Nord just to check. I also use firefox as a browser. Is there some kind of settings I should look into? I'm doing a deep scan with malewarebytes to see if there's a virus and nothing thus far. But I dunno how I could even have picked anything up. I don't download stuff. No pirated stuff. I only download from trusted places and generally watch youtube/netflix, read reddit, play farm games, or play my MMORPG.

    The only thing I can recall happening on my computer was that malwarebytes and Nord were kind of acting up. Malwarebytes was preventing a whole bunch of stuff that seemed related to Nord (as well as websites I wasn't on.) Then Nord stopped working from start-up (it would come up, but wouldn't connect.) Had to exit completely and restart that. That fixed itself three or so weeks ago though and, other then malwarebytes blocking a bunch of stuff (which hasn't happened since I uninstalled Nord), nothing of note comes to mind. Before I uninstalled Nord, I put their DNS number into the Nord VPN connection in my network settings, then into my ethernet settings. That didn't help either.

    edit: My dad wanted to add that the ethernet connection is called ethernet 3. To my knowledge, there's only the one ethernet port. He's wondering if that's somehow misconfigured in my machine? However, I did have an old ethernet cable plugged in which went to the old switch, then put a new one in while also connected that to the modem and new switch. I'm just adding this in case it means something.
