| 1404942 | 2015-07-17 02:32:00 | This is seriously weird. Only two ideas - try a PCI-e NIC and see what the results are Have you ever used iperf before? It's a command line based speed testing program. You could use it to run tests between the PCs and see what speed you get - that could rule out a NIC issue. OR maybe point to something else. If you connected the PCs together, or through a gigabit switch and ran some tests, you should see hopefully around 900Mbps which would rule out the NIC. https://iperf.fr/ |

| 1404943 | 2015-07-17 02:56:00 | wratterus, I never used iperf, just downloaded the zipped file. How do I use it? |

| 1404944 | 2015-07-17 05:08:00 | It's a lot less complicated than it looks haha. Open a command prompt and drag the .exe file you extracted into it on both PCs. On the PC you want to be the 'server', type iperf.exe -s On the 'client PC' type iperf -c then the IP address of the server PC, for example 192.168.1.5 Then hit enter and it will run a test - you can do a bunch and it will show you the results. This is the output I get running iperf between two PCs on a gigabit network here.

| 1404945 | 2015-07-17 09:05:00 | Quite little information on the network side of things but how can an i5 be considered newer than an i7? Although internet speed should not be that far apart, hardware can result in lower speeds, but not by half. I'd be messing around with the drivers, forcing fixed speeds etc. Not sure what your network speed actually is, although i assume its all gigabit network. I would even boot from a linux live cd/usb and run the test, if the results are still the same, then its probably something hardware. Cheers, KK |

| 1404946 | 2015-07-18 01:16:00 | i3, i5 and i7 have been around for several generations now. There are heaps of i5 processors that are newer than i7s. For example I have an i7-860 - one of the original 1156 socket ones. A brand new i5-4690K is about 4-5 years newer, and also actually more powerful. OP - did you get a handle on iPerf? |

| 1404947 | 2015-07-18 03:47:00 | No. Still couldn't figure out what will that achieve? | bk T (215) | ||
| 1404948 | 2015-07-19 03:54:00 | Does the desktop with the slower performance have Wi-Fi at all? If so is it disabled? | Alex B (15479) | ||
| 1404949 | 2015-07-19 05:24:00 | No. it has only LAN. | bk T (215) | ||
| 1404950 | 2015-07-19 22:08:00 | The idea with testing with iPerf was to see if the issue still occurs with standard network traffic - totally excluding the internet connection. | wratterus (105) | ||
