Laptop connects fine at home but not anywhere else. How can I fix this?

I have a Lenovo laptop that's a couple years old. At home it connects to Wi-Fi perfectly with no issues. I brought it to school and tried to connect but it won't connect to any other Wi-Fi places.

What's wrong with my computer?

I have a Sony Vaio E Series laptop (SVE15128CXS) that has a Core i7 processor and Nvidia 4000HD graphics card. I think the graphics card is on board.

If it is possible which graphics card would you recommend for a cheap or moderate price?

What laptop would suit me best?

So I've looked around at many "find out what is best for you" sites and haven't been successful in finding a laptop that would work for me.

Price range I can go up to around £500 but obviously wouldn't mind less.
Also impartial to refurbished ones. Any advice would be awesome; thanks!

What's eating up my PC's memory?

I have a Lenovo and recently I'm getting a message "You're computer is low on memory" even when I have only two-three tabs of google chrome open, a document or two, and notes. I have four gigs RAM. Usually restarting my laptop would fix it but now even when I start it, I get low memory. With nothing open. How can I fix this?

Added (1). When I get low memory, the programs actually crash-especially Google chrome so it isn't a false notification. Also task manager shows 95-100% memory usage.
