Slow wireless - Intel AC2160 card

[goombawaho]

One of my customers complained of slow wifi at her house on her laptop in particular. I had her bring it to her office so I could check it out in general. I updated all the drivers, BIOS, cleaned out temp files. It seems to be running fine other than internet. The office wifi is ONLY 2.4GHz band, Comcast Business Class 50Mbps using old DSL modem as access point. Her laptop is a Dell Inspiron 3558 with Windows 10 64-bit 6GB of RAM and a Samsung EVO850 SSD.

Here is the performance at the office for her laptop and my laptop right next to the access point. My laptop has an Intel AC7260 card in it.
My laptop on wifi 15.8 download/3.6 upload 2nd run 15.1/3.2
Her laptop on wifi 1.9 download/2.1 upload 2nd run 1.9/3.3

My laptop on ethernet 19.8/3.3
Her laptop on ethernet 1.8/4.3

So, I'm confused. Her machine is not just slow on wifi, which is all she ever uses at home.
Was thinking of trying a router with a 5GHz band, but that doesn't explain slowness on ethernet!!!

I did the SFC /SCANNOW No problems found
Anti-virus is just the built-in Windows Defender

I have uninstalled all unnecessary programs and disabled lots of services, but the fact that a clean boot didn't fix the problem should be telling to everyone.

You know something else that comes to mind that would affect both wifi and wired LAN... MTU.



Just my $.02

Well - I did a reload of Windows 10 from scratch, deleted all partitions on the drive. SEEMS to be working, but that was at my house and I am now waiting for the customer to say it's working at her house.

She lives in an area where houses are close together and I don't have the 5GHz band enabled on her router. I may have to enable the 5GHz band to avoid interference on the 2.4GHz band. I had disabled 5GHz because she was relatively far away from her router with the laptop. So many complications.
