There is this one Laptop that connects to the same wifi that I'm using and it keeps disconnecting at random intervals and when it does connects, the laptop can barely loads any website. I already update the Windows to the latest version, AP to the latest version and Modem firmware to the latest version, also reinstall the wifi driver on the laptop but it keeps on disconnecting on random intervals.
I already run out of ideas what might be the problem. Other devices like my laptop and my mobile devices are just fine

Google up "How to flush device DNS", this might help
Also, "forget" all Wi-fi names on the laptop, then rejoin the network
What model adapter is the laptop using ?? What router are you using ??
Otherwise, it's quite hard to pinpoint what is the actual problem / solution, as it may be hardware-related

Disable intel software, use windows to manage wifi

Change the WiFi channel on your router might help. And sometimes, using the latest driver doesn't always means better, try downgrading the driver to previous older version and do a scan on your computer for malware that could be the culprit of the random disconnections.

Also, check the black and white cables whether they are connected correctly (not reversed) on the WiFi card.

If you connected to 2.4GHz, and keep disconnecting, too much electromagnetic interference around you, 2.4GHz wifi usually unusable if you life in a neighborhood with tons of 2.4GHz AP. If 5GHz, your adapter or router need a 5GHz antenna. You can either get repeater (might be slower), Homeplug, or setup a wifi bridge if you have spare router. I've tried a lot of wifi adapter, basically nothing beats the performance of wifi bridge. Expensive wifi adapter still sucks compares to it https://www.asus.com/sg/support/FAQ/1043884/

Flush DNS didn't help at long run. Infact, sometimes it work sometimes not but I can't keep doing this forever
The wifi adapter is the default one from Asus I guess.
Also no intel software installed.
I haven't tried changing that channel, I'll try that later. It happens to my friends laptop who connect to the same wifi too so yeah, maybe router or AP problem

You keep telling us your problem without mentioning your hardware eg laptop model, router spec, what band and channel, no one would be able to help you,
Wifi disconnection has nothing to do with DNS, you troubleshooting in the wrong way.

You probably need to move AP closer to you or you might need thise https://www.dlink.com.sg/product/ac1200-av1...er-starter-kit/
