I don't get Wi-Fi if I step away from router?

I got an iPhone 6 a little over a month ago. I had no problems connecting to Wi-Fi anywhere (school, home etc). As of two weeks ago or so, the Wi-Fi would drop in and out. This wasn't TOO bad or worrisome because I had the same issue on my Android. It got gradually worse, it would stop working for hours on end. Some day were better than others. As of 2 or 3 days ago, it just stopped working completely. So I went to the router and there, perfect Wi-Fi! I walked several feet away and it got weaker and weaker until it stopped by the time I reached my room.
My fine connects and works on Wi-Fi networks just fine anywhere else. We have iPhones, Android's, tablets and a PC that work fine on the home network. I've tried trouble shooting by restarting my phone, turning router on and off, erasing phone network settings, making sure I have latest ios etc.

How can I install an app on iPhone and use it without verifying?

The vShare SE app automatically installs to the device when you connect your device with the vShare program opened. It doesn't require an internet connection on the device and there's no certificate to allow in settings. I'm wanting to recreate this with a different app.

How can I jailbreak without internet access on my device?

I bought an iPhone and it's in airplane mode with find my iPhone on. I want to jailbreak it and delete the icloud account but I'm sure as soon as I connect to a network, it'll trigger an erase or lost mode or something without enough time to verify the certificate for the jailbreak app and jailbreak. I need some way to install and use the app without having to verify it or somehow block the phone from contacting icloud and triggering the erase. I can't edit the hosts because it's not jailbroken. What is the exact site I would have to block?
