Back in the day, when wireless in your home was new and exotic, I often heard it said that it was a crapshoot to try and use equipment from different brands on the same network.
Is that still true? (was it ever?)
I've got a Linksys (pre-Cisco buyout) wireless router and am looking at a D-Link Wireless PCI card for my desktop, but that old voice in the back of my head is warning against it.
