Hi, I have been experiencing wireless problems since upgrading to Leopard, I will have a full signal one minute and then it drops out. I read that the 10.5.2 update was supposed to fix the airport issues, but i'm still having the same problems. I have a Belkin wireless rooter connected to a DSL cable modem, which my iMac G5 connects to wirelessly via the internal Airport card. I then have two Airport express rooters (purchased since upgrading to Leopard) around the house, connected to speakers so I can use Airtunes. I lose connection more when streaming iTunes music to the two Airport Express rooters, and it appears that when I use programs like Photoshop and Illustrator, it increases the network dropouts, which makes me wonder if the iMac is to blame? I'm planning to get a Time Capsule, which will replace the Belkin rooter, so that everything wireless is . I'm not sure that this will make much of a difference though as that will only effect the the internet, and I expect I'll still have problems connecting to the Airports as they connect to the iMac. Is it worth replacing the Airport card inside the iMac, or shall I wait for further updates from ?
