Question Network Speed via ethernet on Desktop PC is terrible ?

[koberulz]

How bad it is varies. Sometimes I can't even load the speed test site. Other times it reports 40 down/20 up, which is what I'm paying for, but when I'm uploading a 12GB video to YouTube, which in the past has taken only a couple of hours, it now takes 6-7. Sometimes I just plain can't watch YouTube at all, I just get a black rectangle with a spinning circle. Other times I can watch, but only in 240p with lots of buffering. Other times...it seems fine.

Tried rebooting the PC, router, etc etc, to no avail.

It's not an internet issue, because once when it was really bad I was trying to do something on my NAS (also wired) and it took a couple of minutes just for a command prompt to load. Trying to navigate in Windows Explorer was painfully slow, and forget about trying to play any video files.

Provide us with the make and model of your router: TP-Link AC1750
- Make and model of motherboard: Gigabyte GA-H170 Gaming 3
Make and model of power supply: No idea TBH
Operating system and driver version: Win7 Pro (driver version?)

You will also need to post your ISP and connection type: I don't believe this is relevant, as the issue seems exclusive to the LAN
You will also need to post the exact number of devices connected to your router (this includes tablets, smart phones, laptops, and desktop PCs) as some routers can only handle a specific number of devices at a time: No idea? Wired, I have my desktop and a Synology DS1819+. And a powerline adapter going to an NVIDIA Shield. Wirelessly...at least two phones, a laptop, two smart TVs, several gaming consoles...but most of these (other than the phones) are off 99% of the time.
Post any and all error messages you are getting from your ISP or Windows itself: N/A


Make and model of switches and how many ports are on each switch: N/A
How many PCs and laptops are connected to the network: Wired? One PC, one NAS, one powerline adapter to an NVIDIA Shield
Whether or not a NAS (Network Attached Storage) or regular server is connected to the network
Whether or not a Wifi router is connected to the network and/or switch: I don't understand the question.
If you are using the internal LAN connection on your motherboard, a USB dongle, or external PCI card: Motherboard.

Tried to open a video file on my NAS about 20 minutes ago. VLC is still sitting there loading it.

Not sure what to suggest it has to be some kind of issue with the pc. I for many years worked for a large company only doing networking so my knowledge outside anything that is pure network is limited.

I can't see anything popping up in the event viewer around the outage times either.

If this was windows 10 I would just recommend you reinstall it since it does a much better job of installing over the top of a old install without destroying files.

The issue is this could also be some hardware issue.

If you want to do some research look for a unix/linux based USB boot image. The is not a install image even though most can also install on your drive if you really want to. It is a special image that runs completely from the USB stick.
Many times it has tools to fix a broken windows install but like most things linux based they use command lines rather than fancy gui windows so they are hard to use by users who are used to android and windows machines.
What almost all have though is a browser pre installed. This would let you run things like youtube and most other internet stuff to test.
The problem is I can't recommend any particular image. The one I use is very old but works in the rare times I need to use it. Maybe someone else on this thread has a recommendation for a new one otherwise you are just going to have to hunt around. This is not something you pay for there are many user supported free ones.

someone else on this thread

There isn't anyone else in this thread, that's half the problem.

I had an Ubuntu install USB until a couple of days ago, when I reset it to use it for something else. Timing!
