Can't get 1000mbps on my new verizon modem and not sure why

skippy647 · Aug 23, 2016

I can't seem to figure out why I can't get gigabit ethernet.

I logged into my router and adjusted my speed for my LAN to 1000.

I also went into my device manager and set my link speed to 1.0gpbs full duplex.
(Setting it to AUTO just gives me 100mbps.)

I ran a diagnosis and it gave me this error.

Connection Status : Failed This adapter does not have link. Make sure the cable is connected and the speed and duplex settings are configured correctly on the adapter and link partner.

Cable Link Status : Failed This adapter does not have link. Make sure the cable is connected and the speed and duplex settings are configured correctly on the adapter and link partner.

If I keep it at 100mbps and run the diagnosis, i get another error code:

Cable Link Status : Failed
Link speed: 100Mbps. The link partner
is not capable of higher speeds.

My motherboard has the capabilities for gigabit ethernet and I absolutely know my cable is good. I can't seem to find a solution for this. This happened with my old modem as well.

I have tried downloading the newest drivers from ASUS since I have a ASUS Motherboard and I still have issues.

1000 Mbps = Mega bits per second 125 MBps = Mega Bytes per second.

So if you are getting 125 MBps. it is correct, and running at it` maximum speed

A bit is four digits, a byte is eight digits.

So 125 Megabytes per second times 8 = 1000 Mbps. to Get the Megabyte value simply divide by 8.

The confusion often comes because of the value displayed can be in Megabytes instead of Megabits.

But I am not getting a three digit download/upload speed.

Here is the ethernet details from the Network Connections window

This is also in my device manager properties for the network adapter

Fairly sure he just jumped to conclusions without reading your post.

If the router and NIC is capable, it has to be the wire. Are you using shielded cable? Did you build the cable yourself? Is it coiled up anywhere? Crossing any other power cables or anything like that? Interference is one of the main reasons a gigabit link will fail.

Are you directly connected to the modem? Or do you connect through a router? If through a router, what's the make/model of the router? If directly connected, what's the make/model of the modem?

What do the router settings look like - you said you set it to 1000? Can you post a screenshot?

Verizon may had given you an older gateway with 100mbits LAN ports. Just don't use them, use your own gigabit switch, they are cheap.

For 1000 Mbps speeds from the router to your system, the cable has to be at least a Cat 6 grade of cable.
The cable must not exceed in the length of the run more than 100 M or 300 ft.

The adaptor on the system must be set manually to 1000Mbps, with full Rx and Tx duplex selected.
Any device that has a slower running Ethernet adaptor also connected to the router, will force the router to select the lowest speed value of the speed of the whole network to that value.

In other words all of the computers that connect to the router via there Ethernet ports on them must be able to run at 1000Mbps.

And set to that value.

Cat 6 cables vary in quality, and cheap ones will often not reach the speeds a good quality cat 6 rated cable should at 1000 Mbps.
If you are using a Cat 5e cable then again it very rarely can achieve the 1000 Mbps transfer speeds set for the network.

Or again it will be due to the length of the cable run.

I am directly connected to the modem.

The model name for verizon is:
FiOS-G1100

Here is a screenshot of t being set to full duplex 1000mbps

Cat 5e will work as well.

as per SinxarKnights, it is almost certainly the cable. Not all Ethernet cables support 1000Mbps, what rating is the cable.

skippy647 · Aug 23, 2016

DeadlyDays :

Cat5e.

I have also tried like 4 different cables and they all failed to get 1000mbps. I can't for the life of me figure this out.

DeadlyDays · Aug 23, 2016

Do you have a premade cable of same or cat6 cable rating laying around you can pop in, maybe the one provided by ISP/Router. if you have to disconnect the router/modem and bring it directly over to the computer and connect the short cable to verify if it is a cable problem or a settings/hardware problem.

skippy647 · Aug 23, 2016

DeadlyDays :

The verizon tech left this specific CAT5e cable for us when he left. I don't think I have a CAT6 Cable around here though.

. I guess ill have to go buy one. I don't feel like that is the issue though but I can't think of anything other than my actual motherboard is screwy. But that would also kinda not make sense.

DeadlyDays · Aug 23, 2016

did you check asus forums to see if there are any known issues with that motherboard or its drivers? it happens

bill001g · Aug 23, 2016

You really need to set both ends to auto or you must hard both to 1g full. I would try to leave both on auto. If you set one to auto and the other to 1000 full the auto side will drop to 100m and many time it will run half duplex. This is because when you hard code it the device does not send the negotiation signals and the auto side take some default value.

It should run perfectly fine with cat5e...make sure it does not say CCA (copper clad aluminum) on your cables. These have massive issues and are not certified cables. You could buy cat6 if you can get if cheaper on sale or something but it will not run faster or better than cat5e when attached to 1g ports.

I assume you have tried other ports on the router but bad ports are extremely rare.

For residential distances (100 meters or less), Cat5e is just fine for gigabit.
Does not have to be Cat6.

skippy647 · Aug 23, 2016

I have tried all these solutions and have run out of ideas. I bought a new network card and am going to plug that into my PCI port and see if that fixes the issue. If not, then I broke the internet

Well thats simply not true, Cat 5e is rated at 1000BaseT up to 100m and has no trouble achieving those speeds at all.

Turns out it was my onboard NIC card that came with the Motherboard. It sucked. I bought a new Gigabit Ethernet NIC and it works perfectly.

Can't get 1000mbps on my new verizon modem and not sure why
