Does my connection drop when I talk to you?
Hi, lately I have been having very bad spikes in packet loss on my computer. Sometimes the spike lasts for an hour, sometimes just a few minutes, but it happens every day like this. This does not happen on any other device on the network. I tested using packetlosstest.com on both my PC and other devices, but only my PC records any packet loss at all.
I am currently using a wired ethernet connection to connect to a wireless range extender. However, the problem is still happening even when I connect directly to the router. Sometimes my computer loses its connection completely to the network. When I run a network troubleshooter, I see an error saying "Ethernet has no valid IP configuration" or "The default gateway is not available." But after waiting about 5 minutes, the connection comes back on itself (though it still has packet loss).
Here are all the devices involved:
* Router: NetGear R6400v2
* Motherboard: ASUS H110M-A
* Extender: Linksys RE4100W
I've tried the following things on my own:
* Powercycling all connected devices
* Installing a new network card (NIC)
* Replacing the ethernet cable
* Resetting the wireless adapter and router back to factory settings
* Updating the ethernet adapters and resetting the IP config and flushing DNS through the command prompt
* Running McAfee anti-virus checks
* Using Task Manager or Resource Manager to watch network processes (there is no strange activity)
I made sure that my computer gets its own IP address automatically instead of me assigning it manually. This exact setup has worked fine for years without any problems. I would be happy to give you more info if you want. Any help would be appreciated, thanks.
You might see that in the event viewer, but do you know if the interface is actually going disconnected or just losing IP addresses? Does it stay broken long enough for you to run IPCONFIG and check if the ethernet port shows up as disconnected? I would test this by connecting directly to the router. It's very common for a wifi extender to have wireless problems and drop the connection between the extender and the router. Everything seems fine on your pc, but it won't work at all. If the port is truly going disconnected, that usually means a hardware issue, most often just bad cables. Be super careful with any cables you use; there are way too many fake flat ones sold out there. It doesn't need to be fancy stuff. Normal cat5e is okay but it must be pure copper wire without CCA and have the right wire size (22 or 24, not thin or flat). If the port does not go disconnected then it's likely a software problem. While it could still be hardware with the port itself, that is unlikely. I would try to manually set the IP address and DNS mostly to eliminate the DHCP server on the router as the cause. I would also turn off IPv6 just because it causes strange issues, but I don't think that is your direct problem.
