My pc randomly disconnect (wired internet)

[jimkromann]

My pc randomly disconnect (wired internet) I have a problem, my internet disconnects randomly and this have been going on for a while, i really don't know how to fix this.

I am on a wired connection and I am connected to the same router as my wife (she is wired too).
I am the only one that are getting those DCs, i tried changing my network cable, resetting the router, flushing my DNS ....
My netcard is an onboard card, but intell stopped supporting my motherboard, I have the latest drivers.


Windows
Windows 7 Home Edition, Version 6.1.7601, Service Pack 1, 64 Bit. Memory (RAM)
12222 MB CPU Info
Intel(R) Core(TM) i7 CPU 870 @ 2.93GHz Network

There are some options on my netcard, but I am unsure if I should mess around with them.






I am open for any suggestions.

Thanks in advance

Jim

Well I have a Realtek PCie GBE Family Controller , and has similar options on yours . I also is a victim to this problem what I did was I go to the power management tab then untick the "Allow the computer to turn off this device to save power " ...

Tell me the results..

Hi Cris1 and thanks for your response, i already have turned off the "Allow the computer to turn off this device to save power " as the only option I have messed around with, as that was the most logic step in my book, sadly it did not help.

I am thinking about buying a separate net card but i pefer not to do this, bit im down to that it could be :
- broken drivers (intell)
- broken netcard
- broken motherboard

OR one of the options on the nedcard that by default is wrong, and needs to be changed.

Are your drivers fully updated ?

Yes, all of them

Have you downloaded something that is not trusted and using internet?
---
Or if not
---
Try resetting your router and modem, then try again..
---
If it still doesn't work\
---
Reset your modem and router, Click on Speed & Duplex and set it to Auto Negation , set TCP and UDP Checksum offload into Rx&Tx Enabled , and lastly turn off Energy Efficient Ethernet...

Backup your files and settings before doing this , it might cause corruption if not done correctly..

Thank you again for responding to my thread

I have tried all of the above, the settings are as you describe, im thinking if it could be a defect on my motherboard ? or (i know this sounds paranoid) the drivers that are buggy, since intell stopped supporting my MB and buggy drivers might force me to buy a new one. (seen printers designed to "self destruct" after 3 years).

Sorry for the late reply , internet has been buggy....

Try and buy a new one... then tell me if it works again

Ok, i bought a new netcard and i still have this issue : /

 

[jimkromann]

I installed Glasswire to monitor my connection, this is my latest connection info from it.

I noticed that the last 3 connection losses have exactly 1 hour between them.

I have tried running

CCleaner
Malwarebytes
Spybot S&D
Superantispyware
Adwcleaner
ComboFix
Norton Antivirus scan. (im using Norton Internet Security)

Wow.. umm go to device manager > network adapters > realtek pcie gbe family controller > advance > disable energy efficient ethernet,green ethernet and lastly large send offload ipv4 and ipv6 > then scroll down until you see speed & duplex set that to auto negation..

Hey Cris1, again thank you for spending your time helping me out,
Well, that looks like the default setting already...

I tried running a tool called Complete Internet Repair, and for now my internet have been stable since.

Tho i would like to wait a bit to see if its solved before i am ready to close this thread.

Which of the options did you check when you did this? I'm currently experiencing the same issues that you are with internet connectivity.
