Suddenly can't connect to the internet only on the laptop?

This happened last night after I uninstalled a few programmes I never use. My router and ISP is fine because the rest of my family can connect to the internet so it's obviously something to do with my laptop. It can't detect any other networks as well as my own router so it looks as if my laptop's been set to a wired network as opposed to a wireless network. Anyone know any solutions for this?

I've already asked this question but just wanted to specify that I'm using windows 7, my ISP is BT and the laptop i'm using is a Sony VAIO. I can't add in details into my previous question since i'm on my iPhone.

I need to choose now between xperia P and iPhone 4s?

A friend of me has two phones. An iPhone 4s 16GB with IOS 7.1.1. The iPhone is two years old but in perfect shape and it works correctly and has no damage. He also has a Sony Xperia P 16GB with android 4.1.2. The Xperia P is one year old and also in perfect shape. I want a phone for whatsapp. I want to be able to type fast on the keyboard. I also want to watch youtube videos on the phone preferable in HD. I listen to music, browsing the web, play some games, i don't want the phone to crash, i want to receive calls without trouble.(I heard some people about call receiving problems). So should I choose the Xperia P or the iPone 4s? And please give good reasons. I need to make a decision quite shortly.

Dropped iphone in soda, it still works but?

Okay so my friend spilt soda all over my Iphone 5 and it's been about 7 hours. Everything seems to be working fine but I'm still a little nervous. I've had it in rice for the past 7 hours but I can't turn the phone off since the top button doesn't work (due to something unrelated). Is it okay that the iphone is in rice while it is still turned on? And should I really be worried if the phone is still acting fine after 7 hours?
