Internet Speed

[BitShack]

This is probably stupidly obvious, but I am confused as to why when I download a file, I only get 10 megabit at most, but Google's speedtest shows I'm running at 80 megabit? I use three network network cards (I know they are working together because when I use only the motherboard's Ethernet port I get 10 megabit on the Google speedtest). Could this be a bottleneck on my HDD or maybe my network cards aren't working together as expected when I download a file?

 

[EDIT]

Basically, files download at one megabyte per second, but they should be downloading at ten megabytes per second.

Downloads in most browsers and clients show it in Bytes per second while speed is advertised in bits per second. 8 bits = 1 byte.

The reason is because data is transmitted in bits (1 or 0) but the smallest consumable amount of information is 1 byte.

 

Another way to tell is MB = MegaBytes while Mb = Megabits

Is it like this in chrome?

Do you have 3 different internet connections for your 3 network cards?

No, they all run under the same IP.

Check the edit to this post if it helps.

You will not get faster internet than what your internet connection will supply no mather how many network cards you have though.

My subscription is 100 megabit...

If I remember correctly, yes, Chrome shows in bytes so you're getting 80Mbit download speed

Wouldn't that mean my download is even slower...

No, 10 megabytes = 80 megabits

1 Byte = 8 Bits

Oh wait no, sorry brain fart...

[BitShack]

Nevermind, I think this is an ISP issue because we get this speed on pretty much every single device on our network no matter what...

All good.

As for your internet plan being 100Mbps and you only getting 80 though, it could depend on the type of service and how congested it is. All ISPs sell lines that are oversubscribed meaning multiple people on a shared amount of bandwidth. If you have a ton of people on a single line (ie 50 people on a 10Gbit line) then if they all hit it at once they'll be limited to 200Mbps. If you're on a cable line or DSL line then you can have line limitations as well due to age and distance from the ISP's node (mostly DSL in these cases).

Are you sure?  Its not usually possible to have an IP address across more than one network card, unless they are setup with some form of trunking.  You would get an IP address conflict, which will either stop them all working or perhaps in your case means its randomly allowing only one of them to function.

 

Try using just whichever is the fastest one, it shouldn't make any performance difference.
