Question Ethernet Status 100.00 when it should be 1000.00 was working before

[PureCarbine]

Hi,

I've got gigabit internet and was able to use it for a few days but noticed my download/upload started capping at 100mbps. I was previously able to get around 950mbps before and have speedtest results showing such. Im using the onboard LAN with my aurous x570 elite which uses the intel i211 gigabit controller.

I thought it was maybe a dead cable, im running a cat6e 15m from the router, but when i checked on my flatmates laptop it was running at the correct speed. The status within the control panel for the adapter shows 100.00 when it showed 1.0gbps before.

I've tried updating ethernet drivers from both intel and gigabyte, rolling back ethernet drivers. replugging the cable mutliple times, restarting the PC and router. Tried different ports. I've checked the BIOS for anything weird, checked the driver settings for anything weird, i tried forcing the speed to 1.0gbps in the driver and it doesnt connect. Nothing weird in the router settings either. Ran virus scans, It works for my mates laptop and with changing nothing it only gives 100.00 on my pc. The only recent change i have with the PC is RAM but it was having this issue with the ram i had before.

Any ideas on what else might work would be great, thanks!

These almost always are bad cables. The only other option it is a bad port. The speeds are done at a very low hardware level it is not really something is driver or software related.

It would be nice if a bad cable would just completely fail. Can be that some wire is just slightly not making proper contant, many times internal where the wire connects to the pin on the plug. These cable can work intermittently and can work on some machine and not others. Some machines are more tolerant of out of spec cables.

Although any cable can fail it has become a much more common problem with all the fake cables on the market. The key cost of any cable is the copper metal. To try to reduce the amount of copper metal the manufacture are making cable from CCA and/or using cables with very thin wires. Those flat cables you see are the most common fake cables, none of these has wire large enough to actually meet the standard to be a certified ethernet cable.

To run gigabit you need nothing special. Cat5e is fine, other ones will not run faster or better but sometime you can get cat6 cheaper.

The key is you need pure copper cables. The wire size must be 22-24 awg. If you do not see that either on the cables themselves or the advertising buy the cables from someone that does. Vendors of quality cables know about all the fake and make it a point to spell out the type of wire their cables use.

Is the router still connected with 1.000 Mbps with your internet provider?

Update the BIOS of your motherboard
If available, update the router´s firmware

be sure the ports of the router are not in green mode or eco or energy saving or similar mode to provide 1Gbit/s

any 3rd party firewall or antivirus installed?

be sure that the ethernet connection is set to private and not public

try the intel update utility to install the latest driver for ethernet

reset the bios

Yeh I was sure it was a bad cable myself but i do think its the port or some other error on the mobo. I the bulit in NIC is of much higher quality than the one on the laptop i tested and i tested the cable throughly on the laptop and found no issues.

I spent the extra to get a high quality cable from a reputable brand, it is a flat cable but its 28AWG CAT6 cable. I had a look at the cable itself and didnt see any issues in the 15m run. I went with cat6 as ive heard of issues if cables are run over on cat5e it can cause such issues.

Thanks for you reply!

Yes the router is showing the correct download/upload and other pcs are able to use it with the same cable.

Lastest BIOS, Lastest router firmware.

Yeh after reseting the driver i disabled the energy saving setting.

I use malwarebytes premuim but have tested with it disabled just in case.

Its set to private.

I used this tool for updating the NIC.

Bios was reset for the new RAM i added and it stayed the same.

Thanks for the ideas anything else you can think of?

This is one of those things that is a absolute.
The standard says the wire size MUST be 22-24. A cable that uses 28 AWG is not a ethernet cable. It is a piece of plastic with wire that just appears to be a cable.

It immediately is in violation of the standard and there is nothing that says it will be compatible with all equipment.

You can't believe most the stuff you hear on the internet. You need to avoid getting data from people that try to sell you something and many silly gamer forums.

Cat5e cable is rated to run 1gbit to the full 100 meters. Cat6 has been a dead cable since it was invented. It was designed to run 1gbit over 2 pair of wires rather than 4. When the equipment manufacture went with the 4 pair solution the cable vendors went into marketing speak mode. They talk about all the technical details trying to snow people with techno babble making them think it is better.

Lately the cost of copper metal has gotten so high that the difference in cost to manufacture even cat6a cable has become a much smaller percentage of the cost. In effect all cables increased in price with thing like cat5e increasing more.

So you buy whatever you can get the cheapest that has the proper wire size. Cat6a cable is certified to run 10gbit at 100 meters.

Oh interesting, i didnt know that about the wire size. Its just one i bought off amazon with 4k+ reviews at 4.4 rating. Seems i got <Mod Edit> on that one.

Could you recommend a reputable brand for a flat cat6a cable at 20m? Im in the UK. Pref on amazon for convience but not a necesity.

I plan to get a 5 gig nic and switch in the future and unfortunately it needs to be flat to run it where i want it to be.

All this still doesnt explain why the port is only running at 100mbps now and why it was running for over a year at the correct speed and it still runs at the correct speed for other machines. I double checked the port and its in great condition. One thing i did notice was in the NIC configuration within the BIOS the options were 10-10-100-100 and auto negotiate, the doubling is for full/half duplex.

I dont have another motherboard to check if that is how it should look in settings for the NIC but i did a fresh BIOS install and it still had the same values. Im messaging gigabyte support to confirm although my hopes for a good reply are low.

You will not find flat cable that has the proper wire size. In addition the different pairs of wires are suppose to be twisted together so they do cancel out any crosstalk.

This is all specified in great detail in the documents on ethernet cable standards.

Cat6a tends to be even thicker because it many times has shielding and a plastic divider in the middle to reduce the amount the pairs move.

That is strange most allow a 1gbit setting. You always need to have it set to auto for home users. The router only runs in auto and if you set the pc to something else the router will not receive the signaling done by auto and might get in the wrong mode.

You might just buy a 5gbit nic now. You never know if it is the cable or the nic that fails. Most times it is the cable. Those flat cable tend to get the end internally lose easier but any cable can have that issue with the thermal cycles it will sometime very slightly lose some contact with the plug internally.

5g can run over cat5e...I think ...the actual documents for the certifications are locked behind paywalls and I have not had access since they updated for 2.5 and 5g standards.

The flat cable do work most the time or nobody could sell them. Problem is with no standards every vendor is different and you have no idea what distance they might work at and how long they will last.

Hmm i see, not sure what to do then for the cable, it has to be flat unfortunately. Yeh i was hoping maybe the flat cable would have some additional regidity but if its out of spec due to being flat seems its pointless.

Yes i found this strange also, Yes i had it set to auto i was just checking if the option was available and it is not.

Yeh i think i will, ill buy the nic first and see if the cable is still causing the issue. If so ill get a new cable but i guess ill have to look about to find a quality flat cable other than on amazon that is closer to spec at least.

thanks for the help i appreciate it!
