Question 5 GHz WiFi keeps dropping speed after 30 minutes ?

[4ScoreSlappy]

I just built a new desktop PC with a Gigabyte X870E AORUS ELITE WIFI7 motherboard. I updated bios and had to manually install Realtek wifi drivers via usb. I connect to my wifi fine, but after roughly 30 minutes the speed will consistently drop from 200mbs down to 1mbps. It always works fine if I immediately disconnect and reconnect, it will just drop again later. I've tried reinstalling the drivers but haven't come up with anything as to why this is happening.

Edit - Here are my specs:
Motherboard - X870E AORUS ELITE WIFI7
Processor - AMD Ryzen 7 9800X3D
Memory - 64GB .SKILL Trident Z5 Neo
Storage - 4TB Samsung 990 EVO Plus SSD M.2
Power Supply - Corsair RM1000X
OS - Microsoft Windows 11 Home x64

Update your post to include full system hardware specs and OS information.

Are you using a USB wireless network adapter? If so, what make and model?

You posted "and had to manually install Realtek wifi drivers via usb". Not sure about the meaning....

For the most part, I suspect that the wireless adapter may be getting hot and then slows as a result.

Especially if a dongle connected to a back USB port. I used USB extension cables to move wireless USB network adapters up and away from the back USB ports. Helped with cooling as well as transmitting and reception.

Use Task Manager and Resource Monitor to observe system performance. Look for what changed/changes when the speed drops.

Another thing you can do is to check Reliability History/Monitor and Event Viewer. Either one or both tools may be capturing some related error codes, warnings, or even informational events preceding the slowdowns.

That 30 minute time frame (if consistent) may be a clue. Check Task Scheduler for anything being triggered at the 30 minute mark.

Could be some app trying to update, backup, or simply phone home.

The built in wifi for the X870E AORUS ELITE WIFI7 comes with an extension dongle, I have moved it to many different places and it doesn't seem to make much of a difference for temperature.

In terms of manually installing realtek drivers I mean that I had to move the files from another PC to this one via flash drive, because I am unable to connect it directly to the router with an Ethernet cable.

The 30 minute time frame isn't completely consistent but I took a look at Reliability History and Monitor and Event Viewer, there are 4 successful windows updates that occurred just as my speed test throttled right now.

The updates are:
9WZDNCRD29V9-MICROSOFT.MICROSOFTOFFICEHUB
9NSTH9KHZDLQ-Microsoft.UI.Xaml.2.8
9N0DX20HK701-Microsoft.WindowsTerminal
Security Intelligence Update for Microsoft Defender Antivirus - KB2267602 (Version 1.421.1725.0) - Current Channel (Broad)

Verify that the antenna cables are tightly connected to the back of the pc.

Unless microsoft moved it again there should be a display that you find in the status screen for the wifi adapter. It should show the upload/download speeds. These though are not really the speeds they represent the data encoding. You can look the exact values up and determine things like if you are using mimo and how strong the signals are. You might see different upload and download rates because one unit may hear the other better/worse.

Key is do these numbers change and do they drop to really low rates when you have issues.

If the numbers look ok it could be something non wifi related. Try to test as close as possible to the router....note if you have some messy mesh system in your house that could also be the cause.

Could be the wifi chip is defective, do you have a USB wifi device even if it is older you can test if it stable speed.

In general you really want to not use wifi for a desktop machine if you have any other option. If you have coax you can use MoCA and you can even use powerline networks. Generally most people on this site use their machine for gaming. Gaming really does not work well with wifi.

Do those updates continuously occur/reoccur?

I did some quick google searches on the listed updates,

I found KB2267602 on my system - simple definition update and to be expected.

As for the other three listed updates - not so sure. Is the system in question being used development?

Regarding, for example, "9NSTH9KHZDLQ-Microsoft.UI.Xaml.2.8" l found:

https://answers.microsoft.com/en-us...hy-is-it/34d031f3-922e-4884-847a-5ad9d09ba9db

The results from "9WZDNCRD29V9-MICROSOFT.MICROSOFTOFFICEHUB" were not all directly helpful. However, you know your system and environment.

Are you using Windows Terminal? That also seems to be a factor.

Three concerns then: 1) are those updates applicable and, 2) what is the true source of the updates, 3) why - if indeed the case - do the updates keep reoccurring?

My thoughts being that the updates installed code that is now running on the system and becomes active when triggered by system events.

I would use Process Explorer (Microsoft, free) and Task Scheduler to look for any processes that may be running in the background and/or triggered sometime around that 30 minute mark.

Watch the networking parameters/graphs via Task Manager and Resource Monitor as well.

Wifi /network status screens:

• Select the Start button, then type settings. Select Settings > Network & internet .
• Right-click the Network or Wi-Fi icon on the taskbar, then select Network and internet settings.

Premise being that if the speeds are sometimes as expected then something else is interferring that drops the speed. May be that the problem is not necessary the wifi adapter.
