Mine never looses connectivity. i have a DLINK G band router, Vonage, XBOX360, PS3, A Mini, Macbook, and a dell laptop and Tivo all hooked up with max bandwidth usage. still no problems...yet.
Netgear is where your going wrong. They WILL work with Macs, but there is no support for them. DLINK, and APPLE branded routers. even a linksys has apple support for connection..
1. Unplug all network cables from it.
2. Hold reset button on the back, you may need a pin or a pen to click it in.
3. Hold that button in til all the lights blink and turn off. youll see the router reset.
4. After a complete reset. hook in all other cables including the cable/dsl modem. rebooth both router and modem so they will connnect to each other.
5. goto a wired connected computer 192.168.0.0 or 192.168.0.1 or whatever your login # is to config the router. type that in and start over. This time. JUST change the router SID (network name) and goto the CHANNEL SETTING. and change it to like 2 or 9 keep it off CH 10. EVERYONE uses that default this can corrupt data speed and create packet loss. Changing the channel will just keep a more positive direct connection at all times.
If this doesnt work..... call netgear and try to get some support. Or just replace it with a better router.
Hope this helps man
