Virgin Media Super Hub keeps dropping out. Why?

I recently switch to Virgin Media as my internet provider. It's the super hub with two channels - 5GHz and a 2.4GHz one.

My Mac, iPhone and amazon tablet all connect to the 5GHz channel and everything is perfect, runs brilliantly.

However, the Dell laptop, which is my Dads, could only for whatever reason pick up the 2G channel. Not a problem, I guess, just another channel, right? However, for some reason, it can't go more that 10 minutes without dropping Wi-Fi connection.

Why? How do I fix it?

IPhone 5s to 6s on Virgin Mobile?

I was wanting to buy an iPhone 6s directly from Apple. It gives an option to buy a "SIM-Free" iPhone. Would I be able to simply take the SIM card from my current iPhone 5s and switch it over to the 6s?

My iPhone 5 screen is beyond repair and I need to access my photos. What can I do?

My iPhone 5 screen literally broke off the rest of my phone so now I can't access it. I tried plugging my phone into my laptop to use iTunes and get my stuff though there but it says I need to confirm from my iphone, which obviously I can't. Also, apparently my icloud was switched off because I went on it and it has nothing saved.Is there any other way to access everything on my phone or at least my photos?

Help w/ buying IPHONE & PLAN?

Okay, I really want an iPhone. My dad and I share a plan on Metro, and our Android phones barely work anymore.

Would it be cheaper for us both to get iPhones with a shared plan --- or should we just make a separate plan for me and he'd stay with Metro? We're really low on money & he doesn't want to pay more than $50-60 per month.

If I got one, should I get the IPhone 6S or IPhone 6 (or another)? Finally, Which is cheaper: T-Mobile, Sprint, or AT&T?

Basically, what I'm asking is what's the cheapest (1) IPhone, (2) Plan, (3) Provider, and is it cheaper for us to share a plan (4)?

Please be nice in your responses because I clearly don't know a lot about this.

If I login my new Apple ID on old Iphone, will all my apps disappear?

I have always been using my husband's Apple ID on my Iphone to download apps. Recently I've opened my own Apple ID. But if I sign out my husband's Apple ID on my Iphone and sign in with my own Apple ID, will all the apps on my Iphone disappear? Or will they all stay on my Iphone? Do I have to repurchase those apps (eg. Whatsapp?) Thanks!

Added (1). Great, but when say one of my old app that's been installed with my husband's Apple ID needs an update, can I use my new Apple ID to update it or does it have to be the same as the one used when installed (namely my husband's Apple ID)?
