I have always had problems with my data connection at home (almost non-existent, unless I stand outside on my porch), so I have to keep my phone connected to Wi-Fi. I wouldn't trade my Note II for anything (except maybe the Note III), but I have had occasional problems even keeping the Wi-Fi connected in my house, which is not very big.
However, since I did the Kit Kat update yesterday, my phone is dropping and reconnecting to the Wi-Fi every 15-20 minutes, sometimes more than that. I use my phone for absolutely everything in my life, so it is really a problem when it is the most useless when I'm at home. Is anybody else having this problem, and is there any way it can be fixed?
