Will a 10/100 card bottleneck my internet?

post #1 of 8
Thread Starter 
So, I recently signed up for charter high-speed, and when they came to set it all up, the installation guy tells me my NIC is bad. This is unfortunate, because my NIC is integrated into my motherboard, which I purchased like a year ago when I built my machine. Now, I could get a wireless router, (I have a USB wireless card in), or I could just get on eBay and buy a PCI 10/100/1000 card for like $12. But here's my question: Can I cannibalize an old machine for it's 10/100 card, or would this create a severe bottleneck in my internet speed? And if so, is it that much worse than the bottleneck created by, say a N150 router (which I think would top out at 150MB/sec)? Am I really ever going to hit 1000MB/sec? Is it as simple as the lowest MB/sec machine in your chain will be the DL speed you achieve, or is it more complicated? Thanks in advance, OCN.

People probably wont hit 1000 MB/sec for several years.
I cant tell if it will bottleneck your internet until I know what your Isp is and what their "specs" are.

I'm not sure what that guy's talking about... I just checked your motherboard (Biostar A75MH, right?) and the NIC is the Realtek 8111E, which is 10/100/1000. I have that NIC on my motherboard and I have 25 Mbps speeds download and ~1.5-2.0 MBps download speeds.

Ok can't answer your question very well, because I don't know the speed of your internet in the first place. I wouldn't use Wi-Fi, 150MBPs will not be achieved, Ethernet is essential for fast transfers.

If your internet is above 100MBPS then a 10/100 card will bottleneck it, to fully utilise it, assuming your internet will be above 100MBPS you'll need gigabit networking, so a 1000 card, GbE switch, and GbE on your router

Unless you're talking about a different machine than the one in your sig, you'll be fine; the A75MH has a Realtek 8111E gigabit Ethernet controller. Unless you're sure your internet speeds are going to exceed 1 Gb/s (highly unlikely), you're fine. The wireless router only supports 10/100 fast ethernet on the wired ports anyway.

I have a 120Mb/s line, so I recently upgraded all my switches and 1 router to Gb standards (10/100/1000)

When I had my 10/100 stuff, I downloaded at max 12.5MB/s (100:8=12.5)

Now I can reach 14Mb/s (with at ideal would be 120:8=15)


Ok it's fun to download even faster, but in my network it all goes at max speed!!!

But bewere! Now the HDD becomes the bottleneck!

At 10/100 my transfer was about 10MB/s between 2 computers (read/write)

At 1000 my transfer could go til a 125MB/s, but my HDD (tested with CrystalDiskMark) only can handele about 80MB/s. And that is the transfer speed now. 80MB/s read/write.


And just for fun (wanted to make it for myself tongue.gif) here's my current network setup (in Dutch, but you get the point...) But I'm proud of it, it looks nice redface.gif





EDIT: I also see you are mixing two things: MB/s and Mb/s

MB = MegaByte
Mb = MegaBit

So my internet line is 120Mb/s download - 5Mb/s upload (or effectivly downloading at 14MB/s --> 120:8= 15)

Sigh,
There are 8 bits in a byte.

1 gigabit is 125 MB/sec
100 mbit is 12.5 MB/sec

If your internet package is less than 100 mbit, a 100 mbit NIC won't limit your connectivity.

Thank you. So many people don't realize the difference between "B" and "b"
