Question [Q] WiFi won't turn on

Hi all,

I have an unlocked Rogers Note 2. Recently came back from Vegas and I picked up a Ready Sim sim card to use for the weekend. Come back to Canada, insert my Rogers sim and now my wifi won't turn on anymore.

While I was in the US, I had used Will03 SlimKat ROM. I just recently downloaded this ROM to see if the problem would go away.

The problem still exists. Is it possible the Ready Sim APN is still hidden somewhere on the phone and it's messing with my phone? This is a first for me. I'm stumped as to what the problem is.

Any help is greatly appreciated.
