iPhone 6s dropping wifi signal/network
Hi, I just upgraded from an iPhone 5 to a 6s 128GB (9.0.2) yesterday. And before I even connected it to iTunes for the first time I was experiencing wifi issues. It would suddenly drop the connection, forcing me to go into settings and select my wifi network, or in some not so rare cases, it forgets the network entirely and forces me to re-enter the password. I have wifi assist off. And I have done a hard reset. Still nothing. Please help! Thanks.
P.S. I do not believe it is an issue with my router, my iPhone 5 never had an issue with any network I used, today I tried several and each one my 6s kicked me from.
