Hello,
My Laptop is latest MSI GL63D. It has CPU 8300H & Wireless Adapter Intel Wireless-AC 9462. I am running Linux Mint 19 Tara (kernel 4.15.0-29-generic)
I sometimes just can not access WWW. The browser just keeps loading the page to display it eventually. My speed tests were acting funny only on this machine sometimes. I have 10mbps connection at home (10.100.x.x) as well work (192.168.x.x.)
To cross check things - I ran ping tests for an hour (3600 packets) over a period of few weeks against my GW devices. I am seeing packet loss of 6% to 20% for most of the attempts, if not all for all. Today I am not seeing any packet loss at all. But few days back - It was like 30%.
TL;DR - I am facing intermittent connectivity drop on Wireless - that occurs randomly for some time and it goes away on its own. I am suspecting something wrong WiFi adpater Or Wireless Drivers. (Wireless GW at both points is stable for other devices - so can't blame them ATM). I doubt it can be hardware issue in such new machine. So I am suspecting driver/firmware.
Few outputs -

This Intel Page says Kernel 4.14+ do support my wireless adapter. So I doubt upgrading kernel will help, as I have 4.15.
Anyone here is facing similar issue? Particularly with this card over mint or any other distro. I read few posts around looks like new Intel wireless cards are bit shaky with Linux. Any suggestion is much appreciated.
Here is output of my ping tests ran in past - https://pastebin.com/raw/9Y0tKZrL
