Just got a new one.....love it but need help with the following: 1) Keep getting notification (authentication receiving) errors for hotmail boxes that ive tried resetting several times. Even tried deleting and adding again....same issues. 2) set up wifi....shows its connected but keeps disconnecting and reconnecting every few minutes. Changed advanced settings as instructed but same issues. No problems with any other device I use on the same router. 3) I have 4g Lte, do I have to pay extra for wifi hotspot? Thank you in advance for any assistance you can offer me.
