Recently got a new Xiaomi Redmi Note 4X from Goldway with the Global ROM and ever since, I've been unable to connect it to my home wifi. I've entered my password numerous times along with my older phone. It connects just fine to my mobile broadband and my older phone acting as a hotspot.

The same error message shows up 'Authentication problem' and asks me to repeat my Wifi network password. The thing is, 8/10 it fails to connect, the other 20% it just magically connects on its own with no input from me whatsoever but would never connect when I want it to.

Also of note is that when I have no network key, it connects perfectly.

I have the latest 8.2.4 Global ROM.

From the phone's side, I've tried:

Forgetting the network from my phone.
Restarting my phone.
Restarting my phone from the Updater app using the recovery restart option
Soft resetting my phone from the settings menu
Making sure the time zone is set in the right place
Phone is currently connected but if I switched off the phone's wifi and turned it back on, I'll be back at square one.

From the modem side:

Currently using WPA-PSK encryption
I've changed the network key
Reset my modem settings
Changing the encryption type (WPA2, WPA, WEP, etc) - as I said above, having no protection means my phone connects just fine
Internet is running just fine, I even try to connect at the same time as my old phone which connects instantly.

Currently stumped on what else I could do because this would be my first Xiaomi phone - any suggestions?

    On your Wifi modem/router you can try changing

    • the WPA-PSK encryption type from either AES or TKIP (I don't know what you're using, but there's 2 types sp try switching between)
    • the wifi channel/set to manual (anything below 11 if you're using 2.4GHz)

    On the phone. try changing

    • device name to something simple like Redmi4

    reset the cache/factory reset the phone (but backup before you do it)

    This was a huge issue in earlier software updates for the Redmi Series
    I found connecting it to 2.4ghz wireless networks resolved many of the issues with "authenticating"
    Seemed it didn't particulary like connecting to 5ghz networks

    I take it is the MIUI rom ? id flash another on to it ala Nouget 7.1.1 ,

    Now I use the above Rom with ilauncher HD- plus i10os[ from Google playstore] & its a dead ringer in looks.
    Global Rom from a chinese seller ? i'd have some reservations in what may be hidden
    I know my last MIUI rom sent an SMS to London with no notification, as happened to many
