Windows 10: Random and consistent internet disconnections (fixed by reboot)

Problem:

This problem started to occur recently (2-3 months ago). My computer (internet is cable connected) would randomly disconnect within a few hours of being turned on. It tends to happen multiple times a day (approx 1-4 times), every day. The weird thing is, the connection continues to appear online with no disconnection or error signs. But the PC is almost completely disconnected. The issue is only fixed when I completely restart my system. Only to occur again after a few hours. One outlier, however, is that often, when the described disconnection occurs, an individual internet connected application that I am currently using will continue to have internet access, despite the fact that every other software is disconnected. Which tells me, that my computer isn't completely disconnected.

By doing some rudimentary troubleshooting of the router, and using other internet connected devices, I've near confirmed that the problem is exclusive to this machine and not the router or network itself (though, my troubleshooting process there maybe lacking). Whenever the computer disconnections occur, the router is still running, and so is the internet on other devices. I haven't made any significant windows changes recently that would warrant this problem (to my knowledge). Though I cannot discount the numerous w10 background updates.

Computer specs:
ASRock Z87 Extreme 4, Intel i7 4790K, GTX 980, 16GB RAM, Windows 10 Pro (10.0.18362), Bitdefender (no other AV/security software).

Things I've tried:

• Disabling "Allow the Computer to turn off this device to save power" option.
  
• Logging off and back into the windows user.
• Using the builtin w10 troubleshooting tool on the internet connection.
• Restarting the router.
• Changing the router's cable port.
• Switching between cable and Wifi (disconnections persist on both cable and wifi).
• Testing the internet on my mobile devices when my PC disconnects (proving that the problem is exclusive to my PC).
• Enabling hibernation.
• Turning off fast startup.
• Reinstalling Intel adapter driver.
• Updating all the recent w10 updates.
• Reducing my router's MTU (as per an online suggestion).

Things I've considered but not tried:

• Make any updates or changes to my Motherboard's Bios (I've updated it a few months back to resolve a separate problem).
• Reset/reinstall windows (that's not an option currently).

Any help on this problem would be welcome. This is a highly inconvenient problem, and it has recently gotten more frequent, just because. Any guidance to further trouble shoot the source of the problem would also be most welcome.

Thank you.


P.S. I am aware that this type of problem has been asked about multiple times, but I've already read throughout multiple threads, attempting their suggestions with no improvement.

Random internet disconnects

Hi everyone, it seems I need your help again with my tricky internet.

So the problem like the thread name is random internet disconnects, the internet will work fine for a few hours then will lose connection out of a sudden.


I've tried numerous fixes:

- Winsock reset and the likes
-Every option present in Complete internet repair
-To top it off I used the Windows 10 reset feature(Yes I did this after I managed to break my internet completely so I could not connect to the internet anymore, the reset allowed me to go back to square 1 aka random disconnects)

I also called my ISP numerous times and they did these:

-Chopped off my internet cable end and replaced it
-They gave a router to test for 1 week(They told me when the light turn red I have no internet and it did so but sometimes it might have turned off completely, there was 1 case where it definitively took more than usual activating the internet at windows startup)
-They chopped my cable again and they split it in 2, 1 end they considered might be bad and 1 end I plug into the jack
-They said they worked on the pole, I didnt see them so I am doubt full

Some notes: They said they did everything on their end and that my PC is the fault, last thing they are willing to do is replace my internet cable completely, from pole to house-PC.(Funny thing is: I told their manager-Boss lady that my internet cable is Cat 5e, she said o definitively it needs a change that's not a cable for internet. In my head I was like WTF is this a telephone cable ?)

The internet guys seemed unprofessional(among other things for various reasons), when internet first installed on fresh PC they said they can make it connect automaticaly like on old PC but it might dissconect, I was like ok... guess I'll bear up with doing it manually if it means trouble free.

When internet disconnects it's like I click the disconnect button it does not attempt to recconect.

I used a broadband connection, pppoe connection wtih username and password until I tried to call the ISP to make it automatic, they refused and told me to do it miself... I hooked up the old PC and took all the settings and now the connection is automatic.

When internet fails now, the internet icon does not change colour, sign etc, it remains as if I have a stable internet but it acts like I have no internet but since it is automatic the internet comes back in under 15s.

I told the ISP to check the pole in front of my house, they said it has nothing to do with my internet since the internet box is on another pole, but they did put a ladder to the pole, watched for 10 sec and said: Yeah, everything seems fine.

I dont think my PC is at fault since I was no the one assembling it, I also think Windows 10 has nothing to do with my problem, I got to this conclusion when I hooked up old PC and it disconnects also.

I dont really have a happy history with this ISP, I use them only because the cheap-fast internet.

I didnt tell the ISP to check the house because I dont think they will do it.

I would gladly change ISP If I know the problem is definitively not at my end.

I have this problem for over 21 days on new PC, the ISP says my neighours dont have any internet problems-My reply is my neighours dont use the internet that much, one being a mechanic, the other one beying a very old lady but except of the lady he told me about some kinds a few houses back.(I also was not aware of my neighours even using the same ISP)


Well guess these are all the major things I did, hope you guys can help me.

 

Random Internet Disconnect, whats up ?

don't get me wrong here.
I mean there are a few steps that I know of which no one has suggested.

The reason why I ask ADSL or Cable is because they work differently (obviously).
Since its Cable I wont bother with ADSL for now.

You 100% correct about the MAC address because cable authentic via MAC address.
But there are heaps of simple things he can do before he contacts his ISP which may just get him to waste his time, such as checking the lights on the modem which usually are from top down

Power
Receive
Send
Online
PC Link
Activity
Standby

If the power light doesn't go solid green it indicates a power problem.
check power cables.

If receive and send light aren't flashing signal problem.
check coaxial cable connection (also its a good idea to disconnect it and reconnect it to reset the signal)

If receive is on and send is flashing.
You can adjust the signal frequency inside the interface of the modem.

I used to work in a ISP and majority of the time just disconnecting the Coaxial cable and reconnecting it solves the problem. Also adjusting the has helped in situations.

 

Random Reboots

I've had, as the title suggests, random reboots for the length of the time since I've built my computer (2 years roughly) and they're completely inexplicable.

It happens under no load, high load, watching movies, listening to music, playing games, browsing the web, sitting by itself in the room when the my sleeping monitor is even saying WTF?!

There aren't any Events to view other than the usual 0xC*D event when the service just shrugs at me.

Any thoughts or suggestions? Maybe someone has had the same problem before and it was just a loose molex connection? I'm baffled.
