Hi;

.

I have two computers, both Windows 7 OS.

One is an older desktop and the other is my work laptop.

Both are in my home office, and connected (CAT5e) to the same router. 

My cable company lists my rated (wired) download speed at 50Mbs.

.

My laptop on the speedtest.comcast.net website, when connected by CAT5e shows a

download speed of between 60-90 Mbs (and often 100 plus).

While my desktop computer under the same conditions is only showing a download speed of 25-40 Mbs. 

.

Would the difference be the network card/motherboard in the older desktop computer,

slowing its download speed? 

.

P.S>  I did switch out the CAT5e cable to my older desktop computer to eliminate a possibly damaged CAT5e cable as the source of the problem.  

Same result: speedtest.comcast.net website shows a download speed of between 25-40 Mbs.

My guess is that the laptop has a Gigabit Ethernet port (i.e. maximum theoretical "speed" of 1000 Mbps although in reality you cannot get anywhere near that) while the older desktop likely has a Fast Ethernet port (i.e. maximum theoretical "speed" of 100 Mbps although in reality you cannot get anywhere near that).

That may not explain all of it, but I am certainly guessing that it explains most of it.

Beyond that, other more "mundane" technical differences between the computer (i.e. differences in hard drive speeds, processors, etc) can also impact things.

Thx.

Anyway to tell about the Ethernet Ports?

I tried Belarc Advisor - but didn't really see it identify the Ethernet ports capability.

At most, Belarc Advisor might tell your the brand/model/chipset of the ethernet NIC. From there, you might be able to do a Google search to find out what kind of ethernet port it has.

The other option is to look up the specs of the computers. What brand & model are the computers?

You can certainly get a Gigibit ethernet port on the W520:

http://support.lenovo.com/en_US/detail.page?DocID=PD015362#comm

And considering you said you got download speeds of greater than 100 Mbps on the laptop at times, it HAS to have a Gigibit port. While you are generally lucky to get above 90 Mbps on a "Fast Ethernet" port, you definitely cannot go more than 100 Mbps on a "Fast Ethernet" port.

It it is pretty much a definite that you have Gigabit on the laptop.

For the desktop, do you know the model & brand of the motherboard in the desktop? Belarc Advisor might provide that if you don't know. If you do, we can likely look up the specs.

The other thing is that I believe Windows will automatically detect and list was the connection is...i.e. whether it is 10/100 (i.e. Fast Ethernet) or 10/100/1000 (i.e. Gigabit). To look this up, right click the little network connection icon in the taskbar (looks like a computer monitor with a plug/cord on the left side). This will give you a pop-list...choose "Open Network and Sharing Center". This will open a window that shows a basic schematic of your network. In the middle-ish area, there will be a thing that says "Access Type" and "Connections". Next to "Connection" should be a clickable "Local Area Connection" link. Click it. This will open a Local Area Connection Status window. There should be a "Speed:" section. It should list the maximum possible theoretical speed. For example, on my Windows desktop (that I built myself), it lists 1.0 Gbps since I have a Gigabit port on my motherboard.

Desktop: Speed: 1.0Gbps

Board: NF725M-P43 (MS-7597) 2.0

 
Based upon this, it would appear that these are the specs for your motherboard:

http://www.msi.com/product/mb/NF725GM-P43.html#/?div=Basic

Desktop: Speed: 1.0Gbps


Based upon the above, it does appear you have Gigabit on the desktop as well.

So, at this point, it appears both computers are using Gigabit.

So, that suggests that either other hardware factors are creating the difference or maybe there is something software related on the desktop that is causing a slower connection.

To maybe rule out the latter, you might try booting into Safe Mode with Networking and then run Speedtest and see if there is any change.

Safe Mode with Networking = same result 25-40 Mbps. 
Back to normal mode, used my Advanced System Care Pro and set it to Turbo Mode ON.

SpeedTest Results = 65 - 70 Mbps.

SpeedTest Results in Safe Mode with networking in Turbo Mode = 65-70 Mbps.

A big improvement. 

(Though my work laptop within the same time frame = 148 Mbps.)

At this point, it is likely just other hardware differences (i.e. hard drive speed, CPU, etc). I cannot see why there would be that much of difference, however.

The only other thing is that maybe there is something installed on the desktop that is slowing down the connection...could be some innocent program that just conflicts or has a bug or maybe even some malware (although usually malware if it borks your Internet connection, I believe it is typically much more "severe").

Are you running different security/anti-virus software on the two machines? If you are running a security suite with a firewall, it is possible that it might be messing with the connection.

Any other major difference in terms of software you are running on the two machines?

You may want to consider posting in the "Am I Infected?" forum. I don't really believe the desktop is infected, but it won't hurt anything to post there and see.

OK, you have been a big help.

I am at least getting the rated download of 50 Mbps.

And one other thing, on all computers, even wireless,

the upload has been constant at between 11 and 12 Mbps. 

I mainly use my work laptop during the day,

and another wireless connected ASUS laptop in the evening for e-mail and web browsing.

So, I think I will leave it, Thx.  

I use the desktop mostly as a storage with two external USB connected hard drives for back-up.

Most experts here would agree that System Care Utilities and functions is not advisable to be used for automated performance boost.
