Internet gradually slows down

In my case the problem was the USB Hub I was using to connect to the Internet. Once I directly connected the CAT5 cavble to teh computer the porblem went away.

Best,

Hi,

Safe Mode is a good way to find problems, but the issue I have with it is that if you have a problem like discussed here where the PC has to be on for a while and in use before the problem occurs, it is difficult to use Safe Mode, because from my understanding it requires a restart to go to safe mode and restart usually makes the problem go away anyway.

Is there a way to go to safe mode without restarting and making the problem go away?

Can the PC be used as normal in safe mode over time with normal applications to see if the problem occurs over time?

Thanks for any suggestions.

Hello Arran,

Thank you for the update.

I appreciate your efforts.

I would suggest you to check the Internet speed in safe mode with networking.

Refer:

Advanced startup options (including safe mode)

Please keep us informed.

Thank you

So here are a few possibilities, in looking at things that might be slowing Internet down.

•  it is something IN the PC that is slowing down (because of something like running out of resources)

there are

• it is something communicating between the PC and something else that is slowing down. Maybe either the PC or the other end taking longer to respond
• it is something communicating between the PC and something else that is getting more errors and taking more time trying to recover as time goes by.

 - make sure there are no peer to peer communications going on like other people loading their stuff through your PC.  Many Games or other programs do this.

So for instance,  you can look and see if the resource usage is different when it is working well and when it is slow when doing exactly the same thing. Are any different processes running, is the memory use the same, is the network bandwidth use the same? Not saying you will necessarily find a fix, but may get more clues. Use Task Manager and Resource Manager. If you can fond different processes, you can look up what is using them on the Internet.

Look at the communications on the Ethernet port using a tool like Wireshark. This provides information on all the communications in and out of the PC. Using this it is possible to see if there are any different communications active, or any communications are taking errors or have different response times.  This may help track down the differences between the good times and the bad times.

Unless you are a network engineer or expert you may not be able to use or analyze this. But there are some good engineers that can out there. (I am not one but I have seen them at work.) These kind of problems are hard to solve and you may not even be able to if the problem is at the other end of the communication or is some interaction between your PC and something else you cannot change.

Hi Ratandeep,

There was nothing of use in that link you sent. Going through the suggestions..

I'm going over Cat6 so the wireless points are irrelevant.

It has occurred on two separate PCs so the cable was properly connected to both. That also wouldn't explain why the connection slows down until the PC is restarted.

One PC is a brand new install on a brand new drive. Again, two separate PCs, same issue, no drive corruption.

Neither PC is missing updates.

Both PCs have the same default network connection settings.

I've now moved the new PC across to a separate switch and the issue persists.

Hardware/software problem, that doesn't really narrow it down, it's one or the other.
