Intel® Centrino® Advanced-N 6205 older drivers for Win 10 64bit

Hi, I would like to find where I can download older drivers for an Intel® Centrino® Advanced-N 6205 WIFI adapter installed in a Lenovo T520 notebook running Windows 10 Pro 64bit.
I want to get older drivers in the hope it will solve a performance problem with very slow speeds.

I experienced a similar problem a few years ago and the problem was resolved by installing older drivers. Recently and previously I have tried doing a wireless reset and gone through the settings without success. Hardware tests run without error.
When pinging the router I am getting erratic responses. Another Lenovo notebook with different hardware in the same room doesn't have any problems.

The last version of the Windows 10 driver package that supported the Advanced-N 6205 is version 19.70.0. The package is too large (>75Mb) to attach here, so I have put in my OneDrive area. Here is link for download:!AtacZBU04mo-jd8YI5NJM9tvEQlH6Q. Note that this link will expire in 5 days, so download as soon as you can.
