Download speeds with router

By bldsm ·
I have a Belkin 4 port wired router connected to 4 PCs on one side and a 2mbps cable modem on the other. If the internet is coming into the cable modem at 2mbps than what speed is the router serving the data to the 4 PCs at?

I thought as the NIC is a 10/100 it would probably be 100 mbps but can't measure it. Any internet speed measurements just measure the speed to the cable modem (I think).

Any ideas?
Thanks
Bruce

Your download speed will be limited by the slowest connection in the path. So, the absolute fastest you can get is the 2mbps of your cable connection.

That said, any number of factors can slow down downloads from a specific site. Including the sites bandwidth and number of users at the site.

Further, the 2mbps is the maximum total bandwidth you have to the Internet. If only 1 PC is using the bandwidth, it should download at full speed. If any of the other PCs are using the connection, the speed will be slower, but may not be divided equally.

While the connection from the router to each PC is 100mbps, the router cannot speed up the connection to the cable ISP. You should experience near the full 100 mbps speed if you transfer files from 1 PC to another.

Here is a neat utility that can monitor all of your network connections and transfer speeds:

Your connection measured in MegaBITs per second. Usually PC download measures in MegaBYTEs per second. So, theoretically you should divide 2Mbps by 8, and it will be your "potential" download speed - 250 KBytes/second. In real life, you have 10-50% overhead - TCP/UDP headers, IP addresses, framing headsers, etc. So, if you really have 2 Mbits link, your top download should be about 200-220 KBytes. If you have four PCs downloading something exactly at the same time, you should divide this bandwidth by 4. But again, in real life it's very unikely that everybody will start downloading at whole speed at the same time.

Good luck,

Mike
