Windows 10: My Internet speeds have been dropping drastically from boot.

My internet speed drops from around 70-90 MegaBytes per second do around 3 and stays there until I reset my router again. This has only started recently and I'm not sure why. My ethernet ports are also glowing orange which I'm aware is a sign of a unstable or bad connection but would that still be the case if it's fine for a moment then drops suddenly? I've tried resetting my Network, reinstalling my adapters and resetting my router multiple times.Example On Epic Games

Drop in Internet Speeds on 2.4 GHZ Band.

Hey Friend, this is Gavin Mathos & using Windows 11 Version: 22H2 OS.

I am using Fiber-To-Home (FTTH) Home Broadband Internet Connection. I get proper Faster Internet Speed as per ISP Tariff Plan's when I am connected to 5 GHZ Band, but when I switch to 2.4 GHZ Band Internet Speed drops drastically. Why so???

What can be the reason behind drop in Internet Speed on 2.4 GHZ Band, while proper Faster Faster Internet Speed on 5 GHZ Band. Is this issue of Dual Band ONT Wi-Fi Router / Customer End or is it from ISP side. Please check & let me know. Thanks...

 

DL speed drop

Hi,BenjaminMello

My name is Erik. I'm an Independent Advisor and I'll be glad to help you today.

How many devices that are connected to the internet, possible that you been experience a high traffic connection to your internet,that's why the speed drop while you were downloading and if only one device is connected, I suggest to run a speed test, make sure
to get the download speed and then the Upload speed, if the Upload speed getting only 1mbps and then you have an issue to your connection, and I suggest to contact your service provider and to trace your line connection and asked what is the upload standard
upload speed that you have in the package of your internet, because if your getting a 40 Mbps of speed expect the upload speed should be more than 5 Mbps to 10 mbps.that will depend what packaged that

 

Network speeds drastically reduced overnight.


Issue:Overnight my download speeds have dropped drastically on this PC. Other devices show typical speeds of 65 Mbps down and 10 Mbps up. This PC is showing roughly 5-7 Mbps down and 10 Mbps up on 5 GHz network and around 25 down and 10 up on my 2.4 GHz network. This is consistent over multiple tests and browsers of course.

Info:

• Windows 10-1511 Build 10586.164
• No firewall/AV enabled (Windows Defender disabled in GPEdit.)
• Linksys WMP600N Wireless adapter (802.11 b/g/n Dual band).
• D-Link DIR-850L router (802.11b/g/n/ac Dual band).

What I've tried/checked so far:

• Malwarebytes turns up nothing on full system scan.
• Task Manager / Resource Monitor shows nothing is using network out of the ordinary.
• Tried 4 different WLAN driver versions with the same results no matter which is installed.
• Ran TCP/IP stack reset (netsh i i r r).
• Reset winsocks (netsh winsock reset).
• Flushed DNS.
• Restarted PC.
• Powercycled router/modem.

Attempting Ethernet would be extremely challenging and I'm 99% certain this is specific to the WLAN adapter. Any suggestions or ideas would be greatly appreciated.
