I'm having trouble with my Internet speeds. So I just recent build a pc and everything is fine. I installed the Intel drivers and connected to the internet. It connects but I'm only half the speed I should be getting.
My normal speed is 20mbps but speedtest.net is only showing 10. It can't be my ISP (which is TWC if anyone is asking) because my other devices like my laptop and my smartphone are showing 20 down.
Heres my system:
CPU: i5 4430
HSF: Stock cooler
Mobo: Gigabyte Z87MX-D3H
GPU: x2 MSI R7950-3GD5/OC BE
RAM: Crucial Ballistix Tactical Tracer 8GB dual channel
PSU: Silencer High Performance Power Supply 750 Watt 80+ (It's a subdivision of OCZ)
HDD: Seagate Barracuda 7200RPM 3TB
SSD: Samsung 840 Evo 120 GB
Case: Corsair Obsidian 350D
Edit: I am using the stock adapter that is on the motherboard. I know for a fact that the cable is good because I used it on my laptop and it ran fine. Its a CAT5E cable. I also ran IPERF and its giving me the same results, 10 mbps.
run iperf between your comp and your laptop, is there a bottleneck there? if indeed you are limited to 10Mb/s on the NIC, you'll see the same limitation to any other device on the network. What is your link rate/duplex on the interface? Ensure you are linked at the same rate as the the port on the switch and are running full duplex. try replacing the cable? defective cables are a very common reason for performance issues, especially when it affects only one device on a network. You might also try a different switch port. – MaQleod – 2013-11-07T11:09:39.107
Can you provide specific information ( in the question itself ) on the ethernet adapter? I suspect this is either one of two things, one you can fix by changing a setting the other you can't without diferent hardware. If you are using a ADSL and/or Cable Modem specific model information is required to help you. – Ramhound – 2013-11-07T13:19:05.993
You don't say whether this is wired or wireless (and Intel makes both). But if wired, I'd suggest you check the cable, as MaQleod says, but more because sometimes people simply grab the wrong (type of) cable too, and it's easy to check. 10Mb speed suggests not having Cat5 cable. – Debra – 2013-11-07T14:23:55.127
