WIFI SIGNAL DROP ASUS ZENFONE 3 LASER

[mishaalwaheed_k]

Since last 4 days, I am facing weak wifi signal problem. When my phone is in the same room as the router, it shows full signals but when I move a little away from the room, it shows zero signal. I don't know why wifi signal drops to zero when I enter any other room. While the other devices connected to the same router show full signals even outside of the house.
Apparently there is no damage to the device. I have already done almost all suggestions given on the internet like restarting my device, doing network reset, checking for the system update and forgetting the password and turning wifi on again. However, there's no avail.
Someone on the internet said to wipe wifi antenna but my phone's back case is fixed. I can't open it.
I can't go to the repair shop due to Covid 19 lockdown.
If anyone of you have any suggestions?
Is factory data settings worth doing ?
Device: ASUS ZENFONE 3 LASER
SOFTWARE: 7.1.1

Hi mishaalwaheed.k
Thank you for your asking. Kindly refer to the tips below for troubleshooting.
1. Before you try "Factory data reset", I suggest you to try to enter "Safe Mode" first. If wifi works well in "Safe Mode", please check on any disturbance from the installed 3rd party Apps

2. For "doing network reset", do you mean "Network settings reset" on phone or on the router?
3. Check SMMI test
