Any idea how to solve my wired network problem?

EpicBob 1,942 101 August 29, 2016 at 02:30 AM
I recently had some major computer issues so I reinstalled Windows 10. It solved all issues but one: my Internet connection is less than half the speed that I'm supposed to get from my Internet provider. I've checked every other computer in the house, have run speed test and every computer but mine has been getting the right download speed. My computer is plugged into a gigabit switch which is plugged into a wall Ethernet outlet. I used to get the appropriate speed, but not anymore. I tried reinstalling the lan driver, rolling it back, and have reinstalled Win 10 multiple times. I looked around on various forums and some people recommended deleting an AMD program for similar issues, but I don't have anything of the sort installed since I have a GTX 1080.

If you have no idea how to repair it, do you have any idea how much repairs of this sort tend to run at local shops or Best Buy? My PC is custom built by me, so my guess is local would be the way to go. If it'll probably be a lot, though, I might just sell the motherboard, RAM and CPU and get a i7 6700k, but of course that'll be pricey and probably overkill for gaming except for maybe Dolphin.

Check what link speed your NIC is negotiating at... wiring might be crappy and, although unlikely, it could be low, something like 10Mbps. Also post what Internet speed you are getting on other devices, what you should be getting and what you are getting on the bunk computer. Have you also tried installing a NIC and testing that? Have you tried updating the drivers for your current NIC?

could it be a faulty wire? try the same wire with a different computer. try a different wire with the same computer.

What speed are you getting, and what speed should you be getting? Are you wired direct to the modem, or going through switches and/or routers? Post mobo model number, too.

When you reinstalled Win10 did you format before installing, or install over your old version? When you reinstalled the LAN driver, did you uninstall the old one? Where did you get it, and which versions did you have and did you install?

All the suggestions here are solid good things to try.

OP What problems did you have with your PC to start? It might help explain your trouble.
Details, model numbers etc are always good to have. Right now we have no idea what you have in your PC if your using your onboard NIC or an addon card etc. Details of the network could help too.

Make sure the NIC isn't going into power save mode too or isn't being forced into a slower speed mode by something. Stranger things have happened.

Before i built essentially a new PC I would replace the NIC with a USB 3 version probably or a PCIE card. Both are cheap and useful down the road if it doesn't fix. NIC do go bad, I have fought them at work from time to time. Cables go bad, well the ends can.

google adapter's model for driver instead of download from motherboard maker.

my integrated one says "Realtek RTL8168B/8111B Family PCI-E Gigabit Ethernet "

be careful don't download something like DriverToolkitInstaller.exe , you clicked the wrong download button

Just waiting on the OP response before saying anything else. All suggestions are good for-starters so OP has plenty to consider.

easiest thing is to get a new network cable and try and other port on the router to eliminate them as the issue. Also consider replacing cable between cable modem and router

What type of ethernet cable are you using? If it's Cat5, you'll be limited to 10/100 speeds. Try using a Cat5e or Cat6 cable since your router does support gigabit.
