Hey guys...I got myself a PowerBook G4, trying to weigh my options as far as upgrades go. The airport inside this laptop gives me horrible reception, always has, always will. Would a wireless card give me a significant boost of speed/reception? If you have experience with it, please add your input as I'm trying to justify this purchase if it will have benefits. Example, I'm in my bedroom, 2 floors down is the wireless router (not that far away), and sometimes reception drops to 0...I'd like to have a solid connection.
