AC 8265 slow internet speed

[Mansat]

On a Dell 7290 laptop, I am seeing extremely reduced connection speeds. As an example - on same Wireless network, one laptop gets speed of close to 600 MBPS, whereas this other laptop only gets around 100 MBPS. 

I have updated wireless drivers, but it did not help. 

I also should add that I have seen and tried few suggestions on the other threads to uninstall driver, install latest drivers etc. And none of them have helped. 

Thanks

Hi Mansat, Thank you very much for providing that information.

Just to confirm, is the problem the same when using the wired Internet connection?

What is the distance between the Router and the laptop that is showing the issue?

What is the model of the wireless adapter installed on the laptop that is working properly?

Where or which application did you use to test the Internet speed?

In reference to the model of the Router, does it have a specific model number besides "Xfinity XFi router"?

Hi Mansat, Thank you very much for sharing those details.

Just to let you know, the fact that the issue also happens when using the wired connection indicates that there might be a problem related to hardware with the laptop itself, with a component in the system.

We always recommend to install the Wireless driver provided by the manufacturer of the computer, since that driver was heavily customized by them work with your specific platform.

I looked in Dell's web site and the latest Wireless driver version they have available is 21.110.2.1, A05. Is that the Wireless driver version currently installed? If not please try a clean installation of that driver and once you get the chance please let us know the results:

I did download and install the latest driver from Dell. But that did not help. 

And I agree, that there may be something on my laptop causing this. But how can I dive deeper and find out what is causing the slowdown? Is there any diagnostic tool you can suggest? 

For e.g. tool to find out what software/hardware on my laptop is causing the slowdown

Thanks

Mansat, Thank you very much for providing those updates.

In regard to your question, Intel® does not have a tool currently to detect or confirm what software/hardware component is causing the slowdown issue on the laptop.

However, Dell does have a tool to do that, so what we recommend to do next will be to get in contact directly with them so they can provide all the details about their tool in order for you to be able to use it:
