Help Xperia T won't detect my Wifi network

[Malellis]

Hi guys
I've been facing this problem since this morning . My phone just refuses to detect my router and connect . I don't know what happened , but last night when i went to sleep everything was working fine . The thing is , is that it connects normally to other networks , except mine . I've tried pretty much everything including factory reset and restarting my router by opening and closing it again . PLEASE HELP !

Does anything else connect to your router?

yes all other phones and computers connect without a problem .

Try rebooting your router with a full power cycle... If that doesn't work try forgetting the connection in android
