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?
