Internet on my laptop is not working? - 1

So here's the thing.
The Internet on my laptop (Dell XPS 17, Win 7) is not working. Yet, all the other Wi-Fi enabled devices in my home are. E. G.iPad, Apple Mac, iPhone, HP Desktop.
I have tried everything to my knowledge to try and fix the problem and I have run out of ideas.
Things I have tried are: Trouble shooting, shutting down and restarting, direct connection through Ethernet, deleting some unwanted programs, trying to access modem IP from browser (and failing).
I should also mention that it is picking up and connecting to my Wi-Fi, it just has a small little "!" inside a triangle (I'm pretty sure it's called a "caution sign" I just didn't know for sure so I described it).

Could someone please help, it's been like this for 3 days now and it's becoming an inconvenience.

Mobile Twitter follower request problem?

Today I went on mobile.twitter.com on Safari on my iPhone to see if I had any new follower requests. I had 3 requests and on 1 request i tried clicking on the username (not approve or deny) and the request just disappeared but I was still on the follower requests page, so I automatically thought that it was approved.

I did the same for the other 2 requests out of curiosity and the same thing happened.So, thinking the requests were approved i check my list of followers and it turns out they were not following me. I believe they were either declined or they are hidden somehow. Even on a pc my requests are gone.

Sorry for the length of this but if anyone could help me in my situation or can relate it would greatly be appreciated.

IPhone 4 won't download apps

I have an iPhone 4 and it won't download apps. I buy them, but when I try to download them, they get stuck on waiting, I've had iHeart Radia updating for a week now, and it still says waiting. I've turned my phone on and off many times, that won't work. And I tried resetting by holding the home and lock at the same time, and it still won't work. Anyone solve this yet? Also, i'm on mobile because I have no Internet in my house, I'm using my data plan.
