My internet connection's been randomly dropping for a while. I was using Devolo powerline adaptors that worked fine before the problem started. So I replaced those with some Solwise adaptors, new ethernet cables and even a new router, but same problem.

So now running a length of ethernet cable from router to pc and it just dropped again!
Each time it does it, I do the Windows troubleshoot problems and it fixes it saying the error was; default gateway is not available.

So I'm guessing it's the network adaptor at fault? Installed latest drivers for it, turned off power saving option so anything else I can check?

Thanks, theres nothing else connected. Currently using a USB wireless adaptor and that's been stable.
The only free slot on my board is PCI.
 
I was using the Sky supplied D-link router, but have the new sky Q hub now and it still happens.
I've just put the ethernet cable back in and now in Win10, the connection shows as the router name, before it just said network 2 so maybe that will help.
 
Well I'm still getting connection drops. Seemed be around same time every night.
So I uninstalled my security program thinking it might be a firewall issue, but lost it again this afternoon. Thinking maybe it happens while I'm streaming video on youtube, NowTV :confused:

Is the router and/or NIC Gigabit capable? You can try setting the link speed to 100mbps, full duplex rather than Auto negotiate and see if it remains stable. It'll be under properties in the device manager. If there's no option then it may be possible to set in the BIOS or router.

thanks, i did try the duplex setting, still dropped.

Are you sure it's the ethernet connection dropping and not the internet connection? What does it say in the router stats?

The lights on the router are still green when it drops, USB wireless works ok so guess connection is fine?
I'm currently trying a laptop on the ethernet cable so will see how that goes.
 
Thanks, log is only showing recent activity for today. When I switched to wireless it was fine so thought internet must be ok. I'll see how the laptop ethernet gets on

Have you considered getting a cheap gigabit pci ethernet card? You can pick up a brand new one from the big stores for like £5-£10.

Yeah I'm considering that as an option, but I've only got PCI slots free, isn't PCI-E meant to be much faster? Otherwise it would mean ditching my soundcard and using onboard sound.

Laptop stayed connected all yesterday, so ordering a Intel network card for the desktop. Will have to remove a soundcard, but good excuse to buy a DAC ;)

How is your PC connected to the router. How many cables/switches/devices etc between you and the router.

Tried connecting via; router> ethernet cable> desktop
router> ethernet cable to powerline adaptor > powerline adaptor ethernet cable to desktop pc.

Only other device that connects to the router is my mobile phone.

Can't see any errors in router logs.

To rule out the new ethernet card, use a direct cable without powerlines.

Yeah I'm testing everything on this new card. It has dropped once since installing, but releasing n renewing the IP it's been stable for over 24 hours so fingers crossed.

Thanks for all the replies chaps. :)
 
Well desktop connection dropped again and I couldn't get it back. While it was down, I was able to get online ok with my phone and laptop so router, phone line must be fine.

Checked event viewer logs and there's a lot errors for;

The server CortanaUI.AppXd4tad4d57t4wtdbnnmb8v2xtzym8c1n8.mca did not register with DCOM within the required timeout.

I've got Cortana disabled.

Then theres some warnings;

Name resolution for the name 96-trouter-cus-b.drip.trouter.io timed out after none of the configured DNS servers responded.

Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address 0x6805CA42469A. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

Intel(R) Gigabit CT Desktop Adapter
Network link is disconnected.

I've gone back to ethernet conenction, dropped again. So think next step is a fresh Win 10 installation.
