What is wrong with the Airport of my old Macbook Pro?

[kotse]

I have 2008 model (not really sure) macbook pro 15 inch, it has Mac OS X 10.6.8.
It cannot connect or detect any wifi access point anymore.
Is it a hardware issue or a software/OS issue?
I even tried configuring the laptop as a internet hotspot but my Iphone cannot detect it.
I am currently downloading Mountain Lion and I'll to see if it would fix the problem once I am done installing it.
What seems to be the problem?

Could be the OS, you'll find out soon, or you can run AHT and see if there are any Hardware issues.

Please let me know if you find out- mine is doing the same things and it's really annoying. It will connect for between 5 and 30 minutes but then the signal drops and it will not let me reconnect- just keeps asking me for the password and then says connection timeout. After this it stops and will not even find my WIFI. Very annoying. Strange bit is I have another one exactly the same that seems to be working fine- not sure why one works and one doesnt when they have exactly the same settings. I've tried everything I have found on the interent but had much luck this far
