    We have 2 Macbooks, one is from 9-2009 the other 8-2010 (my work laptop). The older one has had a lot of problems holding a wireless signal. All other devices (iPhone, other Macbooks belonging to friends, etc) work well. Ethernet is fine. The fluctuating signal tends to happen on other networks (on a recent vacation).

    OSx 10.5.8. All other software updates have been installed. We do not have any of the defender / protector malware. I have reset the modem and Airport Extreme a few times. Last night I deleted the preference files and it worked great. I continue to check the signal at the top of the screen and it shows 4/4. However, when using it this morning the signal dropped down to 2/4 and 1/4. For some reason if we click on the airport icon the signal improves. It also helps to sometimes click the airport icon repeatedly. I am currently using the problem computer and it's 4/4 again.

    Any thoughts or recommendations? I was thinking about taking it into my local Apple specialists as it seems limited to only this one Macbook. However, if I can avoid that it would be beneficial (save $ and gain a better understanding of the problems).

    Is it actually losing its connection to the network such that things don't work, or is it just these bars that are the problem?

    It's not working properly. Sorry for not stating that more directly. When I cleaned up the preferences it worked great. However, it can change in an instant and result in slow loading or timing out. Seems to happen sporadically.
    Most of the time (except for immediately after clearing the preference files) it is painfully slow or barely works.

    Sounds like a bad card. The antenna wouldn't act that way.
