Realtek Ethernet Controller Driver Slowing Down Upload Speed Windows 7
Realtek Ethernet Controller Driver Slowing Down Upload Speed On Windows 10

I have the same problem, Realtek PCIe GBE Family Controller, Drivers up to date, 5E cable, and connection is stucked at 100 mb for some unknow reason. On properties i set the value to 1gps/full duplex, speed still stuck at 100mb. Register ocx in windows 10. Reading the MSI forum I have now tried updated the driver of my Qualcomm Killer e2200 Gigabit Ethernet Controller (NDIS 6.30). Killer e2200 network contact and the upload speed is so slow that. I have a new Thinkpad Edge 15 (Core i3 301DBU model). The specs say it has 10/100/1000 Ethernet. The adapter is a Realtek PCIe GBE controller (I assume that stands for Gigabit Ethernet). Mac app opens off screen. I connected the Ethernet to my Gigabit Router (D-Link DIR-655). But I'm only getting 100mbit speed. I looked at the driver settings. Aug 28, 2015 When I checked the WiFi speed I had all the other network adapters disabled apart from the WiFi (Realtek 8185 Extensible 802.11b/g Wireless Device) and when I checked the ethernet I disabled everything but the ethernet (Realtek PCIe GBE Family Controller). The drivers are the latest from Realtek. How to download m file to mac. HOWEVER- HP Pavilion Ethernet cable connect slows speeds down below 6 MPS- Tried new and previous Ethernet cables. HP support site suggest * Realtek PCIe GBE Family Controller Driver upgrades for WIN 10 ---. Ethernet driver Realtek PCIe FE Family Controller ‎ 05:23 PM.

Hey all,
I am having a strange issue with download/upload speeds recently.
The speed is very low (always less than 300kB/s, regardless of transfer direction) when my laptop is first booted. However if I run a speedtest, using speedtest.net, the download and upload speed looks fine and suddenly the connection picks up and starts working perfectly.
I've tried this on various networks and the results are consistent and other devices on my home network are fine, so I'm convinced this is an issue with my laptop and not a problem with the network itself. It's worth noting that a wired connection on the laptop reacts the same way. Switching between wireless and wired connection doesn't fix the issue, so far the only consistent way to 'fix' the transfer speed is to run a speedtest.
Unfortunately I'm not sure what could be causing this issue. I don't really know what other information to include, so I have just listed what I can from the guidelines. Does anyone have any clue what the problem could be? Slowing

Thanks in advance!

Realtek Ethernet Controller Driver Slowing Down Upload Speed On Windows 10

We have recently moved house, so I have had the opportunity to test this issue on a completely fresh network with no other devices. The problem was unaffected. Typically there are between 3-6 wireless devices.on the 5G connection. There are 13 devices connected to the network in total (both WiFi & Wired).

Solution:
The marked answer isn't exactly the solution, but it did lead me to the answer. The issue is with the bundled software LANOptimizer. Please see a couple of comments down for a more detailed answer.

Both my wifi and ethernet connections are suffering from internet transfer speed issues. Speed tests and downloads both show about 1.5mb down. I should be getting around 8mbps. Upload speed and ping are fine.
This is on a new-to-me Samsung NP355 laptop with fresh installation of windows 8. No antivirus. I checked task manager to see if any processes are using bandwidth in the background. Nothing is.
I have cleared DNS cache and temp files, reinstalled windows drivers for LAN and Wireless adapter, tried manufacturer supplied drivers, and even tried older archived drivers for both wireless and LAN adapters. I have power cycled the modem/router unit.
My other laptops (windows 7) are seeing proper 8mb speeds. I contacted att to see if there was some incompatibility with windows 8 and my modem. They were not terribly helpful.
I also added the registry key to disable the 20% bandwidth reserve limiter that is default on windows 8. Nothing I have done has changed the speeds significantly, so I have run out of options I can think of. What else could be the issue? Laptop specs are as follows:
Samsung NP355v5c
Windows 8 Home
1.9mhz AMD A8 CPU
Atheros AR9485 wireless adapter
Realtek PCI Network Controller
Thanks in advance for any advice you might have!
UPDATE: In safe mode with networking, I can only use ethernet (no wifi), but speeds are up to 8mbps as they should be. Upon restart to normal mode, speeds are back down to ~2mbps. The router and modem are one unit so I can't really isolate them, but ATT did offer to replace the unit. It operates my two other laptops, smartphones, and xbox 360 without a hitch, so what could cause one laptop perform differently?
SOLUTION: AMD Catalyst manager's streaming feature was the problem. After disabling that aspect of the software install, the internet speeds went back to normal.
