Try connecting to your wireless router directly instead of via Apple's Airport product. Connect to the router's IP address via Ethernet cable. You can get this from the router's manual (check also for the initial username and password to access the site). Go to the wireless setup from here, and change the name to something that you can recognise. If it is not password protected, make sure that it is. Save it and it'll write itself to its flash memory (your network will briefly not work). Once this is done, open network preferences on your MBP and search for this network using WiFi and not your Ethernet connection. Select it and lock it. Disconnect the Ethernet cable, shut down / or put it to sleep and then see if it works.

I had similar issue, not necessarily the case but check anyway:
System Preferences -> Language and Text -> Formats -> Region
Make sure that the 'Region' is the same place as you are now reciding. I hade change the use of "," to "." since I do most of my wrinting in english. This set my "Region" to "Custom" and I could not connect to my router for allmost a year before I figured this out.
Best of luck

Tried this, not even Ethernet works, to edit the time capsule you don't need to connect to the router's IP address, simply open the application Airport Utility, which for some reason doesn't even open, once I right click it on the dock it always says "Not Responding" , not sure if this is it though, since it seems to work for everyone else, thanks for the help mate.

If ethernet cable is not working, then either the timecapsule (I'm guessing there is no other router) is fried (but then network should no be working for anyone), or your computer has hardware/software issues.
If you have "fibre", try connecting you computer directly into the wall-socket (ethernet), open up system preferences -> network and see what it says. If you get no connection, i would suspect you might have to let someone have a look at the hardware...
You can always (just for tryings sake) create a new user on you MBP, log in and try to connect to the network.
If none of these things work, my two cents is hardware error. If the ethernet connection works with the cable, you should try resetting the TimeCapsule or have this looked at by a proffesional. If the "new user" can connect, then its some setting/bug/glitch/rouge firewall in your current user account. This can be sorted with a little patience.
Exclude one issue at the time (I know its frustrating).
