Internet connection keeps disconnecting and reconnecting frequently

I am having an issue with my internet connection at home. I recently bought a new processor and motherboard for my PC and swapped out the parts. I went through all the steps and re-installed windows installing all of the drivers with no issues. I did this at work where my internet connection is slower about 29 Mbps download speed and had zero issues. As soon as i brought my computer home though where the speed is 2 to 3 times faster my network connection kept disconnecting and reconnecting about every 15 to 30 seconds. I know it is not my internet connection alone because it does not do this with any of my other computers just with the recent setup. I have tried re-installing drivers/updating them. I also re-installed windows 7 twice and tried ubuntu with the same issues. I have brought my computer back and forth from work and home with the same consistent issues. Also not sure if this has anything to do with it but my modem/router at work is plugged in via phone cable and the one at home is a coax cable. I have run out of things to try and any help would be tremendously appreciated!

Hello,

You need to provide some additional information:

Are you connecting wired or wireless? The same way both at home and at work? Wired I suspect but wish to make sure.....

Are you using the motherboard's ethernet connection or did you install (swap in) the original ethernet card? If applicable NIC are you using: make & model?

Are you sure that internet at home is really being disconnected and reconnected versus just "stalled"? Are there any error messages being presented?

What changes are you making to your network device as you change back and forth? You certainly have to configure it differently for the home and work networks. Network name, DNS, IP addressing etc.. For example setting it to Gigabit & full duplex instead of AutoNegoiate. Lots of options within the various properties you can manage. Possibly one of them is a bottleneck at home and not so much at work where the network speed are slower.

Have you used the Performance Tools/Advanced tools/Resourch Montitor etc. to compare performance between work and home? See what is running and what resources are being used both at home and work.

See if you can narrow the issue down a bit more. Thanks.

I am using a wired connection both at home and at work and I am using the onboard network adapter with my motherboard which is the Asus 970A-G43. As far as i know it is being disconnected not stalled in the bottom right hand corner every 20 to 30 seconds it will show as not connected and I wont be able to load any websites then it reestablishes the connection. I have not made any changes to any of my network devices at home or at work. I have zero experience in networking and I am not sure what you mean by all of these configuration settings are these in my bios? also I want to note that I don't think it is the internet or router itself because it works fine on all my other computers/devices. I have not used performance or resource monitors because to be honest I have no idea what any of it means. I was hoping someone could help point me in the right direction

Okay. Let's do the following and focus on just gathering some information and not changing anything.

For now we will set aside any troubleshooting via the performance and resource monitors. They may come into play later if we find that something is bottlenecking your Asus setup and causing the connectivity to drop.

=====

The little icon in the bottom right corner will display a window when you hover the mouse cursor over the icon. When the window appears right click, select "Open Network and Sharing Center".

Then in the upper left corner click "Change Adapter Settings". We are not going to change anything so if you mis-click or otherwise end up on some screen just cancel and go back.

The resultant screen should show you what network connections have been set up on your computer. I would expect at least 2: one for your home network and one for your work network. Not usual to find a couple of stray connections from other network connections that have been set up. They may or may not have been disabled.

Select each connection in turn and click "View status of this connection" in the menu bar above. You need to do that when the connection is working and when the connection is not working (i.e., the red "X"). The main objective is to get you comfortable going in to look at the settings that may eventually need to be changed.

To the left of "View status of this connection" is "Change settings of this connection". Click and "Allow". That screen presents various parameters that can be set to establish a working network connection. There are even more settings deeper in. You can explore those if you wish but, again do not make any changes and just cancel out and go back if you feel something is amiss.

There is also a "Diagnose this connection" choice in menu bar. If one of the connections has a red "X" then you can select that connection and choose to have Windows diagnose it and possibly correct it. Since the home network connection is not what it should be as I understand your posting then probably no harm in proceeding with a diagonosis.

Hopefully there will be no requirements to make any BIOS changes. Also agree that if all the other computers on your network are working then no need to tinker with the router.

The focus is on ensuring that the Asus based computer is properly configured to communicate in the same manner as the other computers and devices on your home network. (Note: At some point you may need to look at one of those "normal/expected speed" computers to compare settings.)


That is enough for now. Just click around, observe, and see if you can get a sense of how it all fits together and works. Usually anyway. :)

Please note and post, as best you can, what you find. Thanks.

Side bar: Who manages and maintains your home network meaning the modem, the router, printer, cabling, configuration, security, etc.? Have you had that person take a look at your computer?

OK so I feel quite dumb but I narrowed down the problem to my Ethernet cable as simple as that is. I tested it earlier by plugging it into my laptop and it seemed just fine so I assumed that was not it. Now that I have acquired a new cable and tested that one it works just fine. I really appreciate all of your advice man and I;m sorry for wastin any time lol

The joys of intermittent problems!

Ethernet cables will do that especially because of their really twisted sense of humor.

Thanks for letting us know. Giving you the credit accordingly.

No waste of time at especially if you go forward and start exploring the adapter configurations and becoming familar with those screens and settings. When the next problem occurs (and one will) you will be a step ahead on things.
