Rich1 & ET: Only the first day with Netgear M314 and the wireless PCI Card... hooked up to a Motorola SB3100. Just got back online - router bombed and had to reboot.
I'd say hard wire is more stable... my laptop could barely get a signal on the second story of an 1,800 sq ft. home. But when it works, downloads of 100kbps.
Jury is still out. I may be returning all this stuff real soon.
