Wi-Fi keeps disconnecting and being extremely slow?

We have a 'main computer' in our living room which has the Comcast internet connection. Then, we also a have a Wi-Fi router that's from the brand Cisco. We have an iPhone, iPad, a laptop, and another computer upstairs. It seems for about 1-2 weeks, the Wi-Fi is working fine, and it has good speed. And then all of a sudden, it doesn't work, or is extremely slow, and doesn't load anything. Before, I used to press the reset, or refresh button on the router, and disconnect the cords from it and put them back in. That USE to work, and now nothing works. Please help. Should we just buy a router that is better? Because I'm pretty sure that the router we bought is the cheapest, and basic router.

Is there any place where I can get one of the old otterbox defender cases?

I have an iphone 4 and the top button is broken because I had one of the otterbox defender cases that was recalled. My old phone case broke and I want to get another otterbox defender case. I was wondering if there's anywhere I can buy one of the old ones that was recalled so it would be significantly cheaper (as my top button is broken already anyways).

Iphone 4S charger not working? - 1

I got my iPhone 4S in December 2011.It worked normally until the past few days when the charger would not charge the phone. Sometimes, I had to fuss with the wire to make it charge, but now I have no luck. There are little "dents" on the top of the charger, but that was there all the time. It also won't charge on my PC. Will getting a new charger fix it? What can I do to make my iPhone start charging again?

Added (1). Well, it's dead now. Hope a new charger works.

Erasing all data off my old iPhone?

I want to delete all the information off of my 3GS so I can sell it as I now have an iPhone 5. When i bought my iPhone 5 it automatically synced all the information (photos, texts, imessages, emails, contacts etc) due to my apple ID/iCloud. If I delete my iCloud account off of my 3GS and then 'erase all content and settings' will this affect my iPhone 5 at all?
