Paying for 1000mbps, but getting 300mbps

[leopreem]

Hello!

Recently I posted a thread wondering why my download speed only goes to like 30mbps with 1gbit internet. I finally figured it out. The issue was that my router only gets 200-400mbps with the built in internet speed tester. On speedtest, the results were the same. Here in Sweden we got a testing site called Bredbandskollen which is the same, basically. But there is something worng about it. For example, my PC only shows 200-400mb/s at tops but the Swedish site shows 1gbit down and 100 up.

But the main reason I'm doing this posts is why my router slows down the internet so much? I have a Linksys EA9500.

Help would be appreciated!

Hello leopreem,

We need to know if you are connected via wireless or wired.

200 to 400 Mbps is about right for wireless if you are standing next to the router.

For wired, your coaxial may not support a full 1 Gbps. The computer you are testing on may not have enough power to process that much data. If you are using any security services on the Linksys then it will reduce throughput.

If you are seeing a full 1 Gbps in front of the Linksys, then connect the computer directly to your modem. If you see a full 1 Gbps, then connect the Linksys directly to the modem and then your computer to the Linksys with no other devices. This includes any wireless devices! Do the test again and see if you are getting any difference in performance.

My experience with people using a full Gbps connection is that they will actually get 700 Mbps. As long as you get to 700 then everything is working as intended.

I'm connected via ethernet so I should be able to get over 700 on speedtests. But it only goes up to 300. While downloading, the download speed only goes to max 30mbps which is about 300mbps. Is there any settings on my computer or the router that has to be changed for Gbps?

Basic Answer:

If you have a 1 Gbps NIC with a modern computer, there are no changes you can make to increase bandwidth.
You can check your router/firewall/modem/edge device and confirm that all your interfaces are set to 1 Gbps Full Duplex or Auto Negotiate. Go through your firewall and disable any security services and turn off wireless, if applicable. With everything disabled do the speed test again to see if you get any improvement.

Advanced Answer:

Download JPERF: http://www.techrepublic.com/blog/linux-and-open-source/using-jperf-to-check-network-performance/

Disconnect your Linksys from the internet and put one computer on your WAN interface and leave your actual computer on its interface. Running the new WAN computer as the server, run JPERF from your personal computer. This test will remove the internet from the equation and allow you to test the throughput capacity of your computer and Linksys.

We want to confirm that your router is the problem and doing a system to system test without the internet is the best way to prove that the Linksys is at fault.

In the end, you may end up with three options: 1) Linksys forums to see if a product expert has additional information, 2) buy a new device, or 3) replace the cabling between your modem with fresh CAT that supports 1+ Gbps speeds.

So are you saying if you test to a site in sweden from your pc you the 1g but you only get 300m on speedtest.

If you can test to any location at 1g it means your pc and router are fine. Explaining the difference between sites on the internet takes a lot of research. Could be there is a bandwidth limitation between your ISP and the ISP the speedtest is using. Also the latency will affect speedtest when you are running as fast as you are. If you were to test a speedtest site in Australia you would see significantly slower response. It makes less difference with a slower connection because the slower connection is bottlenecking it before the latency is.
