Windows 10: My wifi speed on my laptop suddenly dropped overnight???? Now my wifi is super slow.

So up until today 1 am everything was fine. I have a 1gpbs wifi6 connection and i used to get around 500-700Mbps over wifi. Same thing with my phone.I woke up today to find wifi speed on my laptop has just dropped significantly. Its now around 27Mbps. Also the wifi signal is weaker now. I used to get full bars up until i slept at 1 am. Now i barely have 2 bars.Initially i thought its some router problem but All other devices in my house work perfectly and getting over 500Mbps.I have not changed the distance of laptop from router nor have i updated anything recently.My windows auto update is

Slow transfer speed - Wifi

I actually had a similar issue a few months back. My WIFI speeds literally dropped by about 70% overnight. Ethernet was fine. I did everything to solve it. Scanned for spyware, window tweaks, router tweaks. In the end on the verge of given up I reinstalled windows and it solved it. That was my first WIFI issue a decade of WIFI.

 

Super slow internet over wifi connection - issue unknown

My HP Stream 13 has Windows 10 and has a super slow internet over wifi connections. 0.15 Mbps download speed / 0.38 upload speed. My wife's Lenovo laptop gets 39.42 Mbps download speed and 10.25 upload speed from the same location on the same wifi connection.
I can confirm this is not an antivirus issue. It is not a malware issue either. I've reset the entire computer and the speed doesn't change. I've confirmed my wireless adapter's driver is up to date and accurate. I've made sure that there are no issues with
the power management settings. Nothing has worked. Any suggestions?

 

WiFi speed drops to ZERO

The WiFi speed suddenly drops to ZERO. It fluctuates between the maximum speed and zero, and then finally sticks to ZERO. I have tried almost everything like troubleshooting, Re-installing the WiFi driver, Disabling & Enabling the WiFi driver, etc. I have
also tried to connect the same network with the Ethernet and it worked fine. Is this the software issue or some hardware issue?
