Solved Does Airport Card Have To Be Replaced Macbook Core 2 Duo

Chosen Solution

Macbook A1181 2.16 ghz signal fluctuates from one to 3 bars from a total of 4 bars

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.
