Macbook Poor Internet Signal
So my macbook's internet has been quite poor. The signal I receive from my router is poor in some areas of my house, and I know that it contributes a lot. But I can't help but notice that my ipod touch receives wi-fi 10x better than my macbook.... Every spot that I have troubles with internet, the touch has it (not 100%óbut still a solid, non-choppy signal).
The 2nd issue is the same, but comparing it to a pc. My dad's laptop has a great signal in the living room, but mine seems to cut out every now and then (and the signal is never 100%, but about 50%+).
Is it possible to fix/replace the macbook's internal antenna? As this seems to be my problem, or perhaps re-installing the OS fresh? I'm kinda in a pickle and would appreciate any help/suggestions. Thanks!
