[SOLVED] New PC not picking up my proper internet speed.

[Vanrick772]

I use a single ethernet cable (cat5e) to switch between a PC and a PS4. In the task manager under network I can see that it recognizes the 40Mbps I'm supposed to be receiving but my ACTUAL download speed is hard capped at 4Mbps. This problem doesn't occur with the PlayStation. I updated the network adapter's driver as well. What could be causing such a discrepancy? Any help would be greatly appreciated!

The only thing I can think of different between PS4 ethernet and PC ethernet is that PS4 doesn't support IPV6. Try disabling IPV6 on your PC. If that works, then try disabling ipV6 on your router.

I'm plugged directly into the modem.

You can still get IPv6 directly from the modem. Try disabling it on your PC and restart your PC and the modem.

IPv6 does weird things with certain websites, which could include your speedtest website.

And be sure your units are correct. Download speeds on PCs are in BYTES. 4MB/s would be close to 40Mbit internet rate.

40 Megabytes / Second. I turned off IPv6 and re-did a speed test and it actually looked good for once! About a minute later is was back down to 4MB/s....so strange.

No matter the speedtest result my download speed is 4MB/s or lower.

Have you verified your Windows tuning is correct -- https://www.ghacks.net/2016/08/05/windows-10-limiting-internet-speed/

 

[Vanrick772]

IPV6 disabled and tuning disabled. The problem persists. When everything is neutral and I run a test the results seem accurate. Then when actually downloading something it seems to bottleneck at 4 MB/s.

Please keep in mind that:

Lowercase b = bit
Uppercase B = Byte

8 bits = 1 Byte

32Mbps = 4MB/s

I think there was a mistake at my ISP because I am paying for 40 MB* /s not 40Mbps. Thank you for your help.

40MB/s is 320mbps. If you aren't getting that, then you need to call your ISP at this point.
