I finally made the switch and purchased a new MBP about a month ago. So far, I love everything about this computer except the wireless. It really sucks. My wife has a Toshiba that never has any issues on the same router. I have contacted apple support and they tried to blame my router (using a Mikrotik). So I switched the router for a Linksys WRT54G. Same issues with the linksys. I am on vacation this week and have tried to use the MBP at various locations and it seems to drop packets every few minutes regardless of the router. I gave up entirely on using any kind of encryption, because is just didnt work. Dropped out every few seconds. I am using only Mac filtering and it still doesnt work properly. The problem I encounter is that everything will be working fine, and all of a sudden the wireless connection will just break. If I go and try to ping the connection between the MBP and the router, I will have about 80% packet loss until I turn the airport off and back on again. Then I am good for another 5 - 10 minutes. Am I the only one having this problem? What can i do to resolve this? Any help would be greatly appreciated. I am about to the point to go buy a USB wireless adapter and just abandon the airport card.
