Hi. I've had my iPhone 7 for about 4 days, and I'm having wifi troubles. At home over the weekend, I connected the phone to my home wifi no problems - however, whenever I leave the house and return home, I have to manually go into the settings and select the network. The iPhone remembers the password, but I have to select it each time. Slightly annoying. Then today, while at work, I connect to the BT Wifi Hotspot using my BT Broadband login details, something I had to do every time I picked my phone up! The phone kept dropping off the network. It didn't do it whilst I was using the phone, only if I locked it for a period of say, 20 minutes or more. I would have to reconnect to the network, again, selecting it manually (it wouldn't pick it up automatically). The issue at home isn't a big deal - although I'd like to know why it's doing it, as my old mobile (Samsung Note 4) didn't do this. The issue at work - I'm thinking could be a DHCP lease issue, although I sometimes connect my laptop to the network, and the lease on that doesn't expire for 4 hours. I'm thinking that because I'm locking the phone, it loses the IP address? Anyway - question is - is it hardware related, and is there a fix for it - or is it router related? Sorry for the wordy post - thanks in advance.
