My iBook G4 receives a strong wireless signal (i.e., all 4 bars) on my home network, but on my condo complex's network, it only receives 1 bar and feels like dial up. My PC with a Linksys wireless card has a transfer rate of 54Mbps on both networks. I will be cancelling my home network access shortly and do not want to use my PC all of the time. Does the airport card have poor communication with different networks? Are there firmware updates that may help with this? Any other ways to get a stronger signal? I really don't want to have to deal with a USB wireless adapter, but is this my only choice to get better reception on the condo complex's network?
