Vivobook 16 (M1603QA): Unacceptable degradation of networking performance

[NeedToKnowBasis]

Followup on Vivobook 16 (M1603QA): Frequent packet loss and connection drops 

At this point, network performance has significantly degraded, regardless of driver pairss used. The oldest working drivers (WLan 6001.15.117.0 and Bluetooth 1.9.1046.3001) are still the most usuable, however I know have constant jitter and/or packet loss in any networked game w/ fast communications. WiFi also disconnects occasionally on battery, regardless of distance to the source.

Very unfortunate that everything else about the laptop works fine, apart from a very miniscule and rare (used to be more occasional, but not anymore) audio pop when loading streamed content (especially while running background tasks).

If you are certain that there are no abnormalities with your internet source, and the issue lies with the network card of your laptop itself, we recommend uninstalling the network device from the Device Manager and then reinstalling the drivers to confirm. If the problem persists, you may consider restoring the system or taking the laptop to a repair center for assistance from our service team.
