A few hours ago, when I was using my computer to watch some videos, suddenly my Wi-Fi connection dropped. I checked the Wi-Fi panel and found out that aside from my normal Wi-Fi SSID which is WPA/WPA2 secured, there's another Wi-Fi with exact same SSID as mine, but it does not require a password to connect to. I can still see my Wi-Fi signal strong, but I just can't connect to it. When I press the connect button, windows tell me "Failed to connect to network" and android just shows the message "Saved, Secured with WPA/WPA2". I immediately know something is up, and I opened up the android app called Wifi Analyzer to check. That "clone" Wi-Fi, has almost identical address as mine (mine-"b8:a3:86:be:de:b4" clone-"b8:a3:86:be:dd:b4"). So, I tried to connect my laptop with a CAT5 cable, and the internet works (just Wi-Fi is not working). Then I tried to connect to the fake clone Wi-Fi. Upon connecting, a login page showed up (like those in airports where you need to type in additional data to gain access or else you just get a limited connection), telling me to type in my WPA/WPA2 password due to security reasons. That is obviously phishing. Worst part is, I don't know how he can deny any devices from connecting to the normal Wi-Fi. Whenever the clone Wi-Fi is not detected anymore, everything connects to the Wi-Fi just normally.
I have tried the following (which didn't help) :
- rebooted modem and router
- changed SSID of Wi-Fi
- changed password of Wi-Fi
Does anyone have any idea how I can fix this? Thanks for taking your time to read this.
