i think it began with some iteration of ios8 that i've had to turn off wifi and turn it back on to enable internet usage. depending upon my usage, this may happen several times per day. my wife's ipad3 has the same version, since i'm the one to update it, and she does not have such problems. i assume that it is some sort of setting but i sure can't figure it out. i'm presently at ios 8.2.
