I just recently bought a NETGEAR WNR3500L 300Mbps + gigabit ethernet port. I keep hearing that my airport card should handle 300 Mbps just fine. But when I enable it on my netgear router settings my going to "UP TO 300Mbps" from default "Up to 150Mbps" i get horrible bandwidth...like 8Mbps. If i choose 150Mbps, everything opens up. Im going to figure out why 300Mbps mode isn't working. Has anyone been successful?
