Wifi problem. a515-44.

Acer aspire 5 a515-44. Since buying this laptop, the wifi for all devices randomly disconnects from the internet. Only resetting the router (TP-Link) restores our connection. On average, daily, I am resetting the router 15/20 times. When connected, internet speed is fine. I have updated drivers, changed various settings (preferred band, roaming aggressiveness etc etc) AND disabled power saving options. I've tried everything I can think of. On a good day, we can remain connected for around 12 hours, on a bad day, resetting the router three times in ten minutes. I am sure it is this laptop as all devices connect without dropouts until I boot this one. I am loathe to update the BIOS as I have only had this laptop a month or so and don't want to invalidate the warranty or cause further problems. Please help! TIA

To add. Have also updated the router's firmware and disabled bluetooth. The problem persists.
