Windows 10: Where can I find the specific driver I want to restore internet speed?

We have 2 laptops with the same specifications as shown in my profile (Dell Inspiron).

We recently had an issue with very slow internet, and having had the problem before I was able to fix it on one laptop by changing a setting on the Dell Wireless network adapter Properties: on the Advanced tab I changed the bandwidth from 20 only to 20/40 auto (see screenshot below). My download speed improved tenfold.

However, the second laptop had a new hard drive installed a few weeks ago and an different driver was automatically installed for the network adapter. This driver does not have an option to change the bandwidth.

I would like to replace the driver on the second laptop so I can make this change, as it seems to be the solution to the problem. The driver I need is: Qualcomm Atheros Communications Inc. Version 10.0.0.321 Issued 16/06/2015.

Is there somewhere that I can safely download this driver from? Dell does not seem to offer it on their site.

Alternatively, can anyone suggest an alternative solution?

Windows 10 1709 System Restore problems...


That seems to be an attempt at Option 2 in the tutorial, which requires you to
a. Boot to a command prompt (Did you?)
b. You then seem to be mixing steps 3,4 and 5, thus your command is incorrect.

I suggest Option 1 is easier.

If you still have problems, please repost listing each specific step and saying which option from the tutorial you are using. Thanks.

I tried this, but Driver Restore is not in the list of programs that can be unistalled.
