[SOLVED] I'm not getting the full internet speed I'm supposed to.

I can't seem to be getting my full internet speed with an ethernet cable. I tied plugging the ethernet cable into a laptop right beside my desktop and the laptop was getting 1Gbps download and 30Mbps upload on the speedtest.net speed test. But when I try doing the same speed test from the same server on my desktop, I got 300Mbps download and 30Mbps upload. The speed test doesn't detect the 300Mbps directly. It starts at 60Mbps and starts climbing till the end of the speed test to reach 300Mbps. I tried booting up a live Linux disc to see if Windows was the problem, but it seems like it isn't. I then looked up my motherboard to see if it had an ethernet speed cap and it does, but at 1Gbps. It should be enough for my internet speed, right? If my motherboard isn't the problem then I don't know what is. Here are my computer specs for you to see if anything catches your eye:

Thanks for any help!
 
nvm found an answer to it, mainboard is using realtek network card rated for 1Gbit...
but it runs it in four twisted pairs at 250MB each....this technique is done with PAM5 line coding, which is obsolete now (1000BASE-TX), requires different type of cables

new network card migh be needed or better cables

spec sheet of your network card, page13

Would this network card work for me?

It would extremely strange to find any device that support 1000basetx. It was very rare even when it first came out and was a dead protocol from the start. I saw a couple of routers and switches that had support from cisco.
This was way back around year 2000 and your board has web pages for specs even though web did not exist then. This makes it highly unlikely your board is using that. Now it might be and if it is I bet you could sell that board for a lot to someone who collects rare items.

In addition what happens when you attempt to plug a 1000basetx into the modern 1000baset port it will only connect at 100mbps. This would mean you never get 300mbps. Since you do sometime get 300mbps it means the port likely is running at full 1gbit data encoding but there is some other issue.

Since you have already done the key thing I recommend which it trying linux almost has to be some kind of hardware error. Since nic cards are cheap I too would recommend you try that but more because there is some possible strange hardware issue rather than it supporting some older data protocol.
