Device manager says Gigabit Ethernet card but site specs says 100mbps.

Which one is correct?

Can a gigabit card driver be installed on a 100mbps card?
I've gotten network transfer speeds of 60+MB/s (at least that's what windows says), seems to be limited by the 5400rpm HDD.
Laptop is a lenovo z710, dev manager says qualcomm gigabit controller.

 

Under ideal conditions you would get ~100MB/s - so yeah, your card is GB Lan.

 

Alot of cheap laptops (~300 USD and less) only have 10/100 LAN believe it or not. Some companies don't give you 10/100/1000 til you go to 500+ dollar laptops. Though as the old saying goes; you get what you paid for. Most consumers couldn't give a rat's tail about gigabit LAN, they see i5 or i7 and 8 GB RAM and that is enough to sell them on a laptop. Hence the rise of 1368x768 screens on laptops, pitiful, I know.

 

Gigabit is not the name of the company by any chance i know there is an Gigabyte

John.

 

lol dude for laptops like 500 and under, all the big OEMS make no more than 30-40 dollars per computer, and that's with all the trial bloatware on it. Gigabit controllers should literally be like pennies more than a Megabit, it makes no sense. But again, you get what you paid for. Even my 459 dollar Latitude 13 thin buisness notebook had a gigabit LAN.

 

I don't know about AMD, but all of Intel's mobile chipsets have had Gigabit Ethernet since 2007, when the ICH8M south bridge was introduced.

Any Core 2 laptop has Gigabit LAN, even the Atom CPUs do - manufacturers don't even need to add a separate controller since it's integrated into the Intel chipset itself!

Also, best you're gonna get over Gigabit LAN is ~70 MB/s, so it's possible that your 60 MB/s is not because of the HDD, but the Ethernet adapter/cable/configuration...

 

Intel likes to release gimped chipsets with reduced iGPU performance, reduced maximum RAM, and a whole host of other things. And not everyone will use an Intel chip, there are still Broadcomm, Realtek LAN controllers.
