Hello listers. WiFi on my iMac (10.6.7) is acting up. It creates a network that both my iPhone/iPad recognize and join. But I cannot actually transmit/receive. The last time it happens I tried everything I knew (not that much really) and ended up reloading the OS with the latest Apple combo. That worked and all was swell for weeks until today, when the same problem reappeared. Anybody have any suggestions? Winston
