Same Ethernet cable, two PC's, two very different speeds

Braden Fontaine · Aug 17, 2014

MSI A88X-G45 GAMING ATX FM2+ gets 250k-2,000k download speed, board came with MSI Killer Network Manager, ive turned bandwidth control on and off with no change, if i delete the network manager i lose all network capabilities.

Gigabyte GA-F2A88XM-D3H Micro ATX FM2+ gets 50 meg download speed, no network manager installed/required.

Adapter on the MSI A88X-G45 is the Killer e2200 Gigabit Ethernet Controller (NDIS 6.30)

has anyone had similar issues?
has anyone found a solution?

Edit: installed USB WiFi stick and speeds increased, assume Ethernet port is faulty.

Edit2: Speeds have reverted back to the slower speeds as reported originally.

Hello,

Have you used the drivers from the support CD or the default Windows drivers? Please download the latest drivers from the manufacturer's web page.

Cristi72 :

yes, i have loaded the stock drivers that came with the board, same results. i then updated the drivers to the current version and still, same results.

Braden Fontaine :

Try to freshly install the drivers: uninstall the LAN drivers, restart, let Windows installing the LAN, remove the LAN device from Device Manager, restart again and install the new drivers. Also, try to install only the drivers, without that Network Manager. If still not working as intended, limit the speed connection to 10/100 Mbps and see if it changes anything.

As you said, it can be a defective LAN; the LAN worked before or the problem arised from the start?.

It could be also another program which limits the speed (antivirus, firewall, etc.)

You see so many of this type of post and the common denominator seems to be the killer network stuff. Trying to get some magic faster network seems to break more than it gains. The common solution has been to completely remove even the driver for the killer network stuff not just the manager and replace it with either the default driver or one of the intel drivers. Lately though it appears killer has a different chipset that only works with their crap driver so it depends if you can find another driver that is not killer that will work with the chipset you have.

No matter what they claim software running on a PC can not fix the real problem of controlling the traffic being sent from the ISP to your house especially when you have multiple devices in your house.

Removed all traces of the driver and software, plugged in USB WiFi stick and speeds are still below normal. disabled antivirus software and ran speedtest, speeds did not change. ran antivirus and malware scans and found nothing.

Restart in Safe Mode with networking, run speedtest, speeds skyrocket to over 50Mb download. time to hunt for a program that is holding me back?

Complete PC wipe, testing speeds as im installing updates and necessary drivers. narrowed down to an AMD driver installed with Catalyst Control Center, will report back with exact driver once ive pinpointed. odd, the drivers are for the display, but i also have an AMD board so im wondering if there is a conflict somewhere between?

FOUND IT! AMD Quick Stream killed my internet speed. i dont know why or how but once i started fresh i installed everything one driver/program at a time until i found it.
