Maximum 100 Mbps on I129-V network adapter

[justajok3]

My desktop's motherboard is Gigabyte H170M D3H and the specification shows that it supports gigabit network but I can reach maximum 100 mbps network speed only. I tried the Ethernet cable on my laptop and my laptop can reach 1Gbps speed.

Go into setting, Ethernet, Change adapter options. On the Advanced tab, check that the Speed & Duplex is set to Auto Negotiation. It sounds like it might be set to 100Mbps.

It could be that you have a driver issue. Have you downloaded and installed the most current driver from Gigabyte or Intel?

First make sure it's a CAT5e cable, minimum. Ideally CAT6 for gigabit. And what are you connecting it to? laptop <-> desktop or your switch/router is Gigabit? Could be a negotiation issue. You can try and force 1000Mbit or set auto like @Scottray was suggesting.

I have set the speed & duplex into auto negotiation but it shows the link status show that its 100mbps full duplex

I tried to download the latest driver and installed it but it sill can't be fixed

It would be nice if ethernet cable just worked or did not. Cables can be just slightly damaged and one computer will tolerate it and and another will not. The equipment to actually test a marginal cable is way too expensive

The cheapest is to try a brand new cable. Make sure it is pure copper...no CCA. Also avoid any flat or thin cable. You want the wire size between 22-24awg.

You need nothing better than cat5e to get gigabit speeds. If you can get a cat6 or better for the same price or cheaper then that is good but there is no real benefit to paying extra. If you were going to pay extra for anything maybe the brand of cable like belkin. I used to say look for eia/tia markings on the cables but now with amazon and ebay selling outright fraudulent cables I don't know what to say. More buy from a reputable vendor and avoid trying to save $.50

If it is not a cable issue then it has to be the port and you have tried the common fixes. Luckily it is very rare for a port to be bad

You do not need CAT6 for gigabit Ethernet. Minimum spec for 100 meters is CAT5. You can actually use CAT5e to run 10G/BaseT for 33 meters and CAT6 over 50 meters.

Thanks a lot! I fixed it by changing a network adapter
