Motherboard replaced. Now Internet is slow. Different Motherboard impact?

[GGuid]

I have a Dell Inspiron 13 7000 (7359) 2-in-1. The MB was replaced.

WIN10.

Now when I use the Dell support site to scan my system the

Tag and description says Dell Inspiron 15 7000 (7568).

The Intel Dual Band Wireless-AC 3165 is installed and using the latest Intel Drivers by using the Intel driver check utility.

The Dell Inspiron when connected to the 5Ghz wireless, never exceeds ~79 Mbps. .

The router is the latest Xfinity "b" router. My Thinkpad with 5Ghz is getting 130-170 Mbps.

So I don't believe this is the Router.

Also when I connect the Inspiron with the Dell RJ45 to USB connector, the speed never exceeds ~80 Mbps.

So this seems to be related to the laptop.

I checked all the wifi power settings and read the support notes for Adapter settings.

Nothing seems to improve the speeds.

Suggestions?

Suggestion: Go back to Dell and have them provide you support. This is Dell's problem.

Thanks. The board was not replaced by Dell...

Ok, who replaced the motherboard?

I was able to resolve the problem. The issue was the WIN program Smartbytes.

I recommend everyone remove this from their computers.

Right-click on Windows Icon

Select Apps and Features

scroll to the program Smartbytes and remove any software associated with Smartbytes.

My peak speeds went from 70Mpbs to 200Mpbs.

I was very glad it was nothing to do with the motherboard. It was the fact that

the Smartbytes software was activated/installed when the board was installed.

Ah, just another case of shovelware, I mean value added software.

Glad you have it solved.
