Here are the current speeds I know

by Paulo540 In reply to Broadband

Broadband or cable modem will get a maximium of 1.54Mbits/s, similar to a T1 line or full DSL.(At least that's what they tell me) USB, has two speeds currently. USB 1.1 is 12 Mbits/s and USB 2.0 is 480 Mbits/s. Ethernet is a rather broad term. Her are a few examples of the more popular ehternet formats. Ethernet10baseT will get 10Mbits/s, whereas 100baseT will get 100Mbits/s. Then there is Gigabit ethernet which, you guessed it, will get 1000Mbits/s. Of course, there is even higher speeds thanthat coming down the line so to speak. So, to summarize, Ethernet is by far the fastest.

Hardly Matters Right Now

by TomSal In reply to Broadband

First, while the previous poster's figure were pretty much correct in regards to how fast USB, Ethernet and Gigabit Ethernet are..I don't *think* that's what you (David) were asking.

I'm assuming in the context you are talking - you mean is usinga USB connection to a DSL/Cable modem faster than using a Ethernet connection to the DSL/Cable modem.

Right now this answer is relatively simple if you mean simply access a single computer to broadband (ie. at your home). That answer is : It doesn't really matter.

Why? Well if you take into account that most of the national providers of DSL or Cable modem service are sporting a range of about 640 kbps all the way through 2400 kbps (2.4 mbps) then you take into account that even good ol' USB 1 transfers data at 12mb/s and Ethernet is 100 mb/s (I'm being realistic here, nowadays most people use Fast Ethernet and not just Ethernet (ie. 10baseT) ) in both cases the transfer speed between modem and computer is many TIMES greater than the speed from the Internet to modem.

And like the other guy rightly stated if you have USB 2.0 (though I don't know if they have USB 2.0 Cable modems out yet) that would be 480mbs which makes even a T3 connection look stupid (about ten times over).
Now a disclaimer of "reality" if you would: Those speeds are the "published" or "advertised rates" there really are people getting 10mbs Cable modem connections to the Internet from their home, and its VERY common to come accross people nowadays that are double or tripling 1600kbps (My own connection at home averages about 2250kbps - nearly twice that of T1). Different providers in different markets offer different rates, you can tweak your connections, how far your home is physically located from a central office, etc. etc... all these variables can alter the performance of your broadband connection. Hence, the variance in speed.

I would do this. If you are looking for convenience, use USB as you won't have to open your box.

But if you want to do it right, use Ethernet. Then if you build your home network you have the potential for 200Mb/sec transfers in teh home network with full duplexing/100. Also, before Atnt took over my net connection, I was downloading at about 1.0MB/sec. Yes, that's right. MB not b And there's no USB device that will keep up with that as of yet.

No difference

by TheChas In reply to Broadband

For connecting to either a cable or DSL modem, there should be no noticeable speed difference between Ethernet and USB.

If you happen to have an extremely fast connection, it may be possible to 'overwhelm' USB 1.

Another caveat to USB, I agreewith mafrohead that if you have any desire to share the broadband connection with multiple computers, Ethernet is the way to go.

Another good alternative for home use is phone-line networking.

Does it matter?

by David O In reply to Broadband

OK I may be wrong but loosely defined ...
Ethernet describes a physical layer transmission that includes a maximum serial data rate over a given length of a specific type of media. Speeds run up above 2GB and beyond.
USB describes a serial bus. The maximim speed of the bus is also defined by the media the bus is designed for. How fast is a USB port?
The thing is that the bottle neck with either transmission method is inside the computer. Think of a NIC as a HBA just like a USB HBA. If they're plugged into a 66 Mhz PCI slot it doesn't matter which one is faster. You still haven't overcome the speed of the that bus.

here is the crux of it

by MallardtooXX In reply to Broadband

unless you have afully dedicated Cray supercomputer pushing out statistics of weather formations and the proliferation of nuclear arms in the middle east then you will see little to no difference if you use a USB or a Nic connection to your good oldRCA modem. IF you are pulling big time DL speeds (ie mrafrohead, theChas, TomSal, and yes even the duckpod here) then you :
A) suck cause you have really fast internet
B) cannot go any faster than your resident bus speed without some bottlenecking which was stated earlier.
so honestly it really doesn't matter, I just wanted to get my feathers wet on this one =) I award you 1 shot of Windex!

Broadband Know your Limits

by Jaytmoon In reply to Broadband

The difference between the two connections, ethernet are USB are mute if the bandwidth of your preferred isp provider is limited to 10Mb/ps.
Most Cable providers (eg(comcast) only provide for a residential connection speed of 10Mb/ps. I cn't say for sure what the DSL speed is but I believe it's a little slower(on average) than Cable. Unless you are willing to get into the big time with a "Business Account" (using a fiber backbone connection), your hook-up to your PC is only a matter of Configuration Prefernce. (What ever is easier for you). If you plan to "share" your broadband connection with several pc's then you'll need to use the ethernet and a router to share to them.

Doesnt matter

by tanyaclose In reply to Broadband Know your Limit ...

Working for an isp company i hear alot of issues about speed,,,the speed comes from the capped connection from ur isp company thru ur cable,modem and how many people our on ur node in ur area.The difference between usb and nic is nothing! besides the driver if you unplug ur usb while ur pc is on ur gunna loose the driver 9 times outta 10 thats about the only difference.

The other thing that determines your speed is the network protocol if it is corrupt for one reason or another usually redoing it will speed the computer back up again,,

so once again * I * dont think and havent seen any sugnificant speed issue with nic or usb!
