Wired connection capped at 10 Mbps?

I typically have a 30 Mbps downstream and 5 Mbps upstream on my wired desktop computer through a TP-link WDR3500 router. About a week ago I noticed it was a little slow. After doing several speedtests on multiple devices I figured out that all the wireless devices still had the regular speed. My desktop however seems like its capped at 9 Mbps down now. The upstream is unaffected. So, I tried connecting straight to the cable modem. Doing this, it can't ever get a connection. After Windows trying to resolve the issue I get some sort of message saying that the local area connection doesn't have a valid IP address.

I have a feeling it has something to do with this person's problem: http://www.tomshardware.com/answers/id-2616681/connection-mbps.html but I've read and done everything here and can't figure anything out. The status of my local connection is always stuck at 10 Mbps.

I don't know if it has anything to do with the issue, but I started using a VPN (privateinternetaccess) about a month ago. I had several speed issues at first but everything has been working fine for the last 3 or 4 weeks. I don't connect to the VPN very often and all of the above issues are taking place when not connected to the VPN. The VPN just slows everything down more, like half my typical speed.

so you are saying that a wireless device on the same network gets 30 Mbps down and the desktop gets 9?
Which website do you use to do the speedtest?
Are you running the speed test on both devices simultaneously?
Do you have any other software running on the desktop while you are performing the speed test?
A good way to tell if something is going on in the background is to close all programs. Open command prompt and type:
netstat

this will list all active connections
 


That is exactly what I am saying. My wired connection seems to be capped at 9 Mbps while all wireless devices still operate at 30. I use speedtest.net and no other devices or applications are running. When I check the status of my local area connection it says it is only connected at 10 Mbps. I've updated the driver. Uninstalled and reinstalled the driver. Using the same ethernet cable plugged into a laptop I get the 30 Mbps speed. So I assume it has to either be my ethernet port or some setting on my PC that got screwed up somewhere.
 


go to device manager, double click your network adapter and click on the advanced tab. look for Speed & Duplex setting.
let me know whats there and make and model of your network card, if you know it.
 


Auto negotiation
Nvidia nForce 10/100/1000 Mbps it's integrated into my motherboard which is an ASUS M4N78 Pro
 


check the network connection status and let me know what it says
look for speed:

10 Mbps
 


Well, looks like your desktop auto-negotiates with the router 10 Mbps. try changing the auto negotiate option in device manager to 100, if that fails I would check the router settings, try different port on the router. try a different network cable.
 
I've tried changing from auto to 100 full, half, auto 100 full and half. All of these settings won't connect to the network. I've tried changing ports. I also even got out one of my old routers and plugged into that. Nothing has really changed. I did also try installing a wireless network adapter thinking it was a hardware problem but that doesn't really seem to help either. I did connect at 20 Mbps for like 2 minutes then it actually got worse. Maybe like 6Mbps. I'll try to change cables I guess. I'll just have to haul my PC into the living room to get closer.
