IPhone 5s auto-lock and screen dimming?

I just upgraded to the iPhone 5s because my old flip phone broke. I'm wondering if I can turn off auto-lock AND still have the phone screen dim after a minute or two. So far, all I have figured out (I think) is that if the auto-lock is set to never, the screen doesn't dim.

Help or suggestions will be greatly appreciated.

Does AT&T participate in Black Friday?

I want to buy the Motorola Moto X but I only have so much money. Does AT&T participate in Black Friday? Just curious. Also, I believe that this is a good phone but I'm not too sure. I do know that iPhones tend to mess up quickly and I don't want to go through another bad phone. I like androids a whole lot better.

Linksys Router is connected but no internet access?

My Linksys wrt54g says that it is connected, but no internet access even when the Ethernet? Cable is hooked up to the laptop. It is like this for my ipad, iPhone, and second laptop. Last night it was working fine until I accidently pressed the ses button on the front of the router. Then my internet connection was linksys_ses_xxxx. I did the factory reset and it is back to the unprotected linksys, as it originally was before, but now it says connected with excellent strength but no internet access. I have gotten into the setup page by typing 192.168.1.1 into the Internet address bar and typing my password in as admin. I have also tried powering off the router and nothing has worked. I'm not very tech savy so please keep answers as simply worded as possible!
