There are many reasons for connectivity issues, here are some relevant aspects based on your description.
The new Intel® PROSet/Wireless Software and Drivers is expected to work well in most configurations, however, the major changes are for newer adapters and Windows® 10. It is possible that your system works better with an older or OEM driver.
Also, if you applied other updates as well, these may have modified the configuration for your PC.
The main recommendation we can provide is to roll back the driver, or you may check with the Computer Manufacturer Support (Asus*) to get their most recent driver.
Keep in mind that the wireless drivers found in Intel® Download Center are generic versions. The driver or software for your Intel® component might have been changed or replaced by the computer manufacturer. We recommend you work with your computer manufacturer before installing our driver so you don’t lose features or customization.
