I217-V Stuck at 10mbps. have to unplug/replug Ethernet

FLR99 · Oct 18, 2014

Hey all, I am having a problem with my ethernet. I have a Z97X-SLI motherboard with an I217-V ethernet adapter built in. I have all the intel ethernet drivers up to date. My problem is that when I turn on my PC I only get around 10mbps. I then unplug and replug my ethernet cable and when I do I reach the 90mbps that I pay for. I have tried different ethernet cables yet the problem persists. When I set the adapter settings to 100mbps/full duplex it will not connect, only 10mbps/full duplex will work. I only get 100mbps/full duplex when set on auto negotiate after I unplug and replug the ethernet. Any idea whats going on?

Thanks,
FL

Okay first off don't mess with the settings on your Ethernet port and leave it auto negotiate. Dropping down to 10Mbps is correct as it goes to the slowest most common denominator to make a connection if there is any issues. This again is ONLY between the PC and ROUTER, this has NOTHING to do with your Internet speeds, this is about how fast/slow the router is connecting.

Now is this a Router ? or a Router Modem? Personally I am suspicious this is a VERY OLD router as the 'norm' actually is 1Gbps connection on all common routers, but that is between PC A and PC B connected on the same router, not PC A to website XYZ.

Okay so if I understand you correctly, connecting your Desktop computer via WIRED cable to the Modem/Router (I am guessing you meant a combo Modem and Router and not two separate devices) of your service provider (figuring your Cable service as that is the norm for this) which you pay for 100Mbps service contract and you 'see' 10Mbps only unless you unplug and replug in the cable then you shoot up to 90Mbps.

If this is accurate then there is major holes on how your 'perceiving' this / wrong place to be asking what the problem is.

1) Is this your Router or the one from your ISP? If the ISP, have you contacted them for support THAT YOUR PAYING FOR?
2) If the Modem and Router are SEPARATE, what happens when you plug in directly to the modem only?
3) How are you 'gauging' the speed? Running InternetSpeedTest.com or other places isn't accurate when 'repeated' as your web browser cache's the 'download' and 'upload' data, so the next time you 'run' the test it uses the 'cache data' on your PC and NOT actually download / upload new data to provide repeated results. So your 'gauge' may be totally off.
The best tests is to download different large files from a reliable website, like www.filehippo.com. You could download Firefox one time, then download Adobe Reader and see how the speeds were on both. Also this shows from OUTSIDE of your network, your speed from the Computer to the Router (auto negotiate, etc.) wouldn't affect normally how 'fast' or slow the ROUTER is connecting to the Internet.

The ethernet port goes through the wall to a hub or switch, I think it is called, (it says "GreyFox systems") in my laundry room and then from there to the router in another room. The router and modem are seperate, the router is a Netgear R6200 and the modem is the one provided by my ISP which can be both router and modem but we keep them separate, it is a technicolor TC8305C I believe. I have been testing it on speedtest.net but I can do as many speedtests over and over and still get 10 mbps, but once I unplug and replug I will get my max speeds. Any other speed test website gives me the same results...

When I turn the PC on it shows 10mbps/full duplex on the ethernet port settings, but it shows 100mbps/full duplex when I unplug and replug.

It does not make a difference if I plug it into the modem or the router, same results either way.

Okay so I understand you believe it is a issue with the computer, the problem is in your described 'network' there is MANY places and points this can cause the very same issue and for ANY device. So I would do the following and YES I know what I am asking but really you want to be on wired connections and THIS is all potentially hardware problems so NO there isn't another way to do this SORRY!!!

= Try a different computer device in the SAME place as you, doing it the 'same way' that makes it 'not work'. That would be test one. If you can reproduce the issue with a different computer then it is NOT your PC, but somewhere along the network (which is highly likely).

= I know it will be a real pain but we don't want to waste time and money looking at the PC as the problem when it may NOT be. So the second test would be to take the computer (and bring it to another room, try where a 'working' computer is and simply swap to your computer. Do the SAME 'fail' ways, DO you get the SAME result. If you do NOT then it proves it isn't the PC, if you do then it DOES prove to the Hardware maker there may be a problem (can be software related too but very unlikely given what you said so far).

Based on the results we would need to track down the problem. So let me know the results, and YES it has to be done this way UNLESS you have a portable battery powered Ethernet capable 'Line' checker that can do the testing for us.

IMHO the network design here is not Best Practice, and I can identify right off some serious problem points.
