No gigabit on Asrock Z77 extreme 6 Broadcom BCM 57781

[StefanZ]

Hello all

Somehow i can't get gigabit lan (wired) to work on my Asrock Z77 extreme 6 motherboard (2.80 bios).
Working with windows 7 64 bit, and the latest drivers loaded from Broadcom site.
I only get 100 Mbit (amber colored light), and i can't manualy set the speed to 1 Gbit in network card settings.
Only 10 and 100 Mbps full and half duplex and auto negotiation.

Any ideas ????

Is this a new build, or one that previously has been running fine at gigabit speed?

Things to check: replace the ethernet cable and retry, the proper file to download for this board/Win7x64 is "win_k57_x64-15.6.0.10.zip".

What make/model is the connected router/switch/modem that is at the other end of the ethernet cable coming from the computer?

Re: No gigabit on Asrock Z77 extreme 6 Broadcom BCM 57781

I've tried several cables, but that didn't help.
I use the latest driver from the broadcom site (15.6.0.10).
When i connect my computer directly to my other computer, i can not manualy set the speed to 1 Gbit.
Also auto negotiation doesn't give me Gigabit lan.
On my other computer, i can choose 10 or 100 Mbps full or half duplex, 1 Gbps full duplex or auto negotiation in the setting of the network card (Realtek 8111DL).
On the Broadcom 57781, i can only choose 10 or 100 Mbps full or half duplex or auto negotiation, so NO 1 Gbps option.
Amber colored led is blinking.
So no switch or router, but one on one, the Realtek let's me choose 1 Gbps manualy, but the Broadcom doesn't give me that option.
I have this computer for about 1 year now, and never needed 1 Gbps, so i never noticed it before.

So no modem then? No switch and or router either? How do you connect to the internet w/o one of those?

Re: No gigabit on Asrock Z77 extreme 6 Broadcom BCM 57781

Oh, and BTW, my Z77 Extreme6's 57781 DOES NOT present a choice of 1Gb so like you I too only have 10 or 100 Mbps full or half duplex or auto negotiation to choose from.

Mine is set to Auto and that is what it should be set to. There is no reason to change it excepting some rather weird hardware situations.

That it is connecting Amber 100M may well be a result of what it's plugged into at the other end only being 100M capable, and not 1GB. That's why I asked the model/make of whatever it is you connect to the internet with.

Re: No gigabit on Asrock Z77 extreme 6 Broadcom BCM 57781

I connect directly to my other computer's network card (homegroup).
So from one pc to the other.
The other network card is a 1 Gbit card, manualy set to 1 Gbps.
Do you connect it to a 1 Gbps switch or router, and do you get Gigabit lan ?

Re: No gigabit on Asrock Z77 extreme 6 Broadcom BCM 57781

I have both a one Gbps router and switch, with a one Gbps connection into the switch, and I get a one Gbps signal into that PC:



But my board has an Intel NIC. What OS are you using on the ASRock board?

The Realtek 8111DL "network card" you mentioned is really a networking chip, not a network card as far as I can see. How do you "I connect directly to my other computer's network card (homegroup)."? If it really is a network card, "Realtek 8111DL" is not the model or make of the card.

Re: No gigabit on Asrock Z77 extreme 6 Broadcom BCM 57781

@parsec The 8111DL is, best I can tell, in the other computer he's connecting to. I'm assuming he's using ICS(?).


@ Stefan

All my computers connect to a gigabit switch, from there to the router, and finally to the cable modem.

Are you using Windows ICS(Internet Connection Sharing)? Or perhaps some 3rd party app that accomplishes the same thing?

I'd like to see you set both nic's to Auto Negotiate, power both PC's down, then first power up the PC with the 8111DL to all loaded up/running state and then power up the Z77 board. Please reply back what the connecting rate is after performing these steps.

That makes sense, and is simple of course, but were we supposed to assume or know that?

Might also be a language barrier thing, no offense, just a guess.

Re: No gigabit on Asrock Z77 extreme 6 Broadcom BCM 57781

You don't need ICS to connect two computers in a homegroup.
Just 2 network cards (or NIC's), and a utp cable.
I assume, that when you connect a Gigabit nic to another Gigabit nic (BCM 57781 to Realtec 8111DL), you get a Gigabit file transfer.
I only get a 100 Mbps file transfer (11.5 MB/s).
The Realtec 8111DL settings, gives me a 1 Gbps option, but the BCM 57781 does not.

..... but the BCM 57781 does not.

I answered earlier that my driver/options do not either.

What did you see when you did the above?

I just don't understand how the cards and PCs are being connected, when no switch is involved, and a single network input on the Z77 EX 6.

The "other" PC with the 8111DL remains a mystery...

For several years, I've been using a cat6 crossover network cable to directly connect both of my legacy systems using the onboard Realtek RJ-45 ports. This works fine for a simple point to point connection between two computes and it's faster and more reliable than using two cans connected by a string.
Obviously I use wireless network adapters to connect each system to the internet.

I disagree, string is a very underrated transmission medium, it's the type of can used that makes all the difference. Unfortunately, the can standards war caused the adoption of string to fail...

I know about and even have a crossover cable or two, not that they are even needed much anymore. That is not the "how" in my question.

One of the OP's PCs (with the 8111DL chip/NIC) must have dual Ethernet jacks, for an Ethernet signal to come into the PC that passes it on to another. Don't tell me we're talking wireless here...

Re: No gigabit on Asrock Z77 extreme 6 Broadcom BCM 57781

That is not the "how" in my question.

Consider they might not even be connected to the internet via this wired connection. Just two in-home connected via crossover cable PC's. With them typing these msgs out on a third PC.
