does airport card have to be replaced
Macbook A1181 2.16 ghz
signal fluctuates from one to 3 bars from a total of 4 bars
Is this a good question?
It's according to your location.
If you know it's just your computer and not walls or electrical interference then do so. I would first open it and check all connections. If you have another computer next to yours that's receiving a much better signal then replace it.
