Question PC suddenly limits internet speed to 6.5 Mbps

[Marianus]

Hey Everyone,

No problems for 4 years of PC ownership. Randomly happened the other night. Cut out mid game. I have done a full malware scan and driver reinstall.

My computer has suddenly limited my internet speed to 6.5 Mbps. It says “Connected, secured” underneath my SSID in the basic internet access pop out. Also has a 4 bar strength.

I can see the speed via “View Network connections”> right click network > status page. It is a wireless connection.

For 15 or so seconds once first connected the speed is up in the 300’s sometimes even 800’s then it goes back down to 6.5 mbps.

While connected to my iPhone hotspot I get a constant 117 Mbps. Works fine.

Other devices work fine still. I’m wondering if this is a hardware issue. Maybe something to do with a 5G connection. It is a 7+ year old Archer T6E PCIE wifi adapter. I have not tried a quick removal/dust of the card yet. Not that there is much in there.

There is a bunch of options I can see in some menus. No idea how they work.

Any advice would be greatly appreciated.

Can you check and see what BIOS version you're on at this moment of time?

Archer T6E PCIE
Try uninstalling your wireless adapter's drivers, then manually install the latest driver in an elevated command, i.e, Right click installer>Run as Administrator.

Use drivers found here;

but please pay attention to the revision number on your adapter so you've got the right drivers for your adapter.

As for your router, you could see if that's pending a firmware update.

Uninstalled using the tool provided. Made sure its rev 1. Drivers matched and installed using admin.

I am on Bios version F50. I can see that it is aged now. Im assuming updating it is the next step.
