Two Macbook Pros, same model, same room, one gets a lot of bars and a strong connection via airport; the other gets just a couple of bars and a low connection.
I recently acquired a slightly-used (as in used for one day) Macbook Pro (15" -- not one of the models Apple just released).
I tried it in my apartment next to my old Macbook Pro (also 15", about a year older than my new-used one).
My older one got a good wireless signal. My newer one got a crappy wireless signal. They were both equidistant from my
I thought maybe the older one was somehow interfering with the newer one, but I tried the newer one by itself, in a different location. In this new location, everyone else (some on similar macs) got a good signal. I still got a crappy one.
The previous owner told me that he had the same problem with it, and he took it into the Apple Store. They ran some kind of diagnostic program on it and insisted that nothing was wrong. The previous owner concluded that the signal was just weak where he was trying to use it. But unlike me, he didn't test it next to another computer.
I can sometimes get a good signal by turning airport off and on or by going into Network Preferences and hitting Renew DHCP Lease. But the boost in connectivity only lasts a few minutes. (This also might be my imagination. The signal waxes and wanes, so maybe I'm seeing a cause/effect where there isn't one.)
I have also been able to get a strong signal by placing my Macbook right next to the router. If I move even a few feet away, the signal degrades.
