iMac and Airport problems
Im having a problem with my iMac (which i love) and airport wifi..... The iMac is 5 months old and is running OS x 10.5.6 I am using a wireless Netgear modem/router on 802.1n. I have 100% signal strength in the Airport Status bar and it connects perfectly.....however about 4-5 minutes the signal just disappears and the Airport status bar greys out and I lose my wifi connection. When you click on the Airport in the status bar, even the network name has disappeared, and then about 20 seconds later it reappears and reconnects itself automatically. Its like the card is turning itself off and then back on again and rebooting and its doing it like clockwork.
I didn't really notice it at first, but it came to light when i bought a Time Capsule - which after 10 days of failed back ups I took back to the shop thinking it was that that was faulty.
As the problem is still there, i figured it might be a router/modem issue so i got our IT guy to check all the settings and he confirmed it was properly set up and working fine.
I've just bought a Mac Air Book also running Leopard 10.5.6 and the weird thing is that the Airport connection on that is bullet proof, as is the wireless connection on my daughters Windows XP Profession SP3 lap top - which leads me to conclude it has to be either a faulty airport card in the iMac or some sort of software issue ??
Any one got any suggestions how to fix the issue - as its driving me nuts! Is this a known issue ?
