Connect iphone 5 to wifi

Same here. My wife's iOS hasn't been updated, but mine has. Only my phone (iPhone 6s, iOS 10.2) cannot connect when it's NOT on wifi. I am guessing when the app is updated to accommodate it, it will work again. Nothing that can be fixed by ourselves for now...

trouble connecting to my wifi on my iPhone 5s Google Search

passwords are case sensitive, so the problem is possibly just that you have capitals in the password and these are not specifies when entering the password into the iPhone

By no network coverage do you mean no cellular signal or can't connect to your home wifi? If wifi trouble push settings button on iphone. Select and turn on wifi. It will search for available wireless networks. Choose your home wifi, should be the strongest signal, most bars. If you don't know your ssid , look on the sticker on the modem. For instance ssid at&t 2345. Once you select your ssid you need to enter password which is also found on the sticker on modem. Enter password and select join. You should now be connected to your wifi. This will always reconnect automatically when you leave and come back home. If not wifi issue, are you just too far from cell tower to get good signal?

What Type/Brand of router ?????

Apple's iPhone is a multimedia connectivity tool.
As such, the iPhone employs a sophisticated system to keep you connected to the web via WiFi signals so that you can stay up to date with email, mapping and media.
To use the iPhone's WiFi feature just follow these steps.
Tap a network.
If you have not yet used your iPhone's WiFi or if you're in a new WiFi area, the iPhone will show you a list of available networks.
Tap the network that you want to connect to in order to connect.
If there is a password required a little lock icon appears.
Enter the password to connect to locked networks and continue to surf the web.
Monitor your signal.
As you use your iPhone, especially if you're moving around, you should take a look at the signal strength of the connection.
The strength is indicated by a small, black broadcast symbol that stacks arches, or rounded bars, on top of one another.
The more bars there are the better the signal.

Make connecting to WiFi automatic or manual.
The iPhone is equipped to automatically search for available networks and connect you to one.
If you do not want the phone to search for networks, select the "WiFi" option on the phone's menu.
Then select either the on or off option of the "Ask To Join Networks."
Turning this option off requires that you find networks manually.

Forget a network.
Once you connect to a WiFi network once the iPhone automatically remembers the network and connects you to it at a later opportunity.
To forget a network so you don't get automatically connected choose the "WiFi" option on the menu.
Then tap the right arrow button next to one of the networks that the iPhone already remembers. Then tap "Forget This Network" to erase the phone's memory of the network.
