Hello everyone! I use a 100 mbps internet plan from Cox and my PC is a MSI GT73VR 7RF Titan Pro on Windows 10. My wireless router is a Netgear R6300v2 with Firmware Version V1.0.4.28, but it shows different speeds for the wired (ethernet) connection than for Wi-Fi. The Ethernet download speeds are usually around 80 to 95 mbps, but my upload speeds on the ethernet side are super unstable, often dropping down to zero or just a few megabits, especially after running tests. On the other hand, both the wired and wireless downloads go up to about 75-85 mbps, and my wireless uploads usually hit around 10-15 mbps. I've tested these numbers many times and they stay the same every time. I also changed several ethernet cables but nothing helped fix the upload problem. So I think the cables aren't broken. What can I do to make my Ethernet upload speeds go up? Thanks a lot for any tips!

Chipsets are often full of weird things. They have a history of bugs, sometimes fixing one thing but breaking something else. You can't just take them out completely. The only way to remove them is to go to their website and download drivers that don't include the killer features.

Open your router settings and check the Quality of Service (QoS) tab. You'll see a box labeled WMM. It probably needs to be checked, so let's uncheck it first to see if that helps.

I managed to locate the setting you mentioned. But turning QoS off didn't help me get a faster upload speed. Sorry for any inconvenience!

That sounds weird. Did you restart the router after making this change? Basically, QoS limits how fast all devices can send data at once so no one device takes up too much bandwidth. There is a chance some QoS software on your computer slowed things down. It is usually advertised to make games run better with less lag, but VPNs and proxies can also slow connections. Maybe something in your adapter settings caused the issue, though if that were true, downloads would likely be slow too.

The router turned itself off after I changed the settings, but unplugging and plugging in both the router and my modem didn't help either. Since I only run a few devices on internet, it's really not important to turn QoS on or off right now. You probably wouldn't see any difference if Netgear USB Control Center was used for wired ethernet because it's mostly for wireless stuff. Basically, there isn't any special software that controls my internet speed since I don't use a VPN connection.

Well darn... so now we dig into the weeds. In your search bar (next to what is left of the start button) type "Device Manager" and open it. Look for Network Adapters and click it. You will likely see a bunch of adapters. Look for your Ethernet adapter (Killer GB or something similar). Right click it and select properties. In properties, go to the Advanced tab. Here you will see a long list... we are looking for three things: Jumbo frame - if enabled, turn this off ... sometimes that helps but not always. Large Send Offload v2 for IPv4 - if on, please turn it off. Large Send Offload v2 for IPv6 - if you have IPv6 and it's on, please turn it off. Save your changes, restart the computer, and test again... my fingers are crossed.

So, I went into the properties of my Killer E2500 Gigabit Ethernet Controller and turned off both Large Send Offload v2 for IPv4 and IPv6. Jumbo Frame was already set to disabled. After restarting my computer and testing the ethernet speed again, there wasn't any change. It's still getting about 0.2 to 0.5 megabits per second. I also noticed that Large Send Offload (IPv4) is enabled but has never been used before.

Give it a try, though I'm really desperate for something else... Sometimes the E2500 includes that annoying "killer suite." That software handles some speed settings but basically does nothing useful. If you find it on your computer, just uninstall it if possible.

Those chips are full of weird glitches like bugs. Sometimes they have a bug, then fix one but break another thing. You won't be able to remove them all from your system. The only way to get rid of them is to go to their website and download the drivers without those killer features included.
