Running stable, kde and network-manager-gnome. The modem/router
provides two wireless network options - one 2.4 GHz, the other 5.
However, net/mgr only picks up the 2.4 - the 5 doesn't show at all. I
thought maybe the 5 signal wasn't strong enough, so I moved the laptop
right next to the modem, but still no 5. I have an old machine - a
late 2008 Macbook, so I thought maybe it was a hardware problem. I
booted into OSX and it recognized the 5 network and happily
established a wireless connection. Ethernet gives me the 5GHz
connection. I'm at wit's end here. Any advice, pointers, etc.
greatly appreciated.
