Question I need a Wifi Expert!

[RoryC]

I’ve recently been suddenly disconnected from my Wifi network. I had made no changes to my device or router. I can discover the networks although upon imputing my network security key I receive - “unable to connect to this network”.

the confusing thing is that I have 3 other devices in the home all issue free with a stable wifi connection.
I’m also able to hotspot from my phone and create a wifi connection that my computer will connect to easily.
Initially so thought it was an issue with my wifi adapter but how am I then able to connect via hotspot??

have done all the obvious fixes - flushed dns, restarted router + pc, windows trouble shooting, forgetting the network, contacting the ISP, even tried a factory reset….

I’ve watched every YouTube video
Im suspecting it’s and IP issue with the router?
I’m literally begging for an answer at this stage please help!!!

You sure you have the password right? (network security key)
I know, probably so simple you won't even try it.
A capitol Lima (I), looks just like a lowercase India (l)
None of the things you tried so far would address that.
There is also the type of encryption, forgot the TLA's (three letter acronyms)
This has happened to many including myself. Not ashamed to say it.
Just a thought.
