I have the 802.11b wireless router and NICs attached to my DSL line in my house. It's good and bad.
My system:
1 PC hardwired to the router
2 laptops hooked up with wireless
1) BAD!-I have two of the 2.4 gig cordless phones in my house and when one is being used, the wireless laptops just about disconnect. They both run the same frequencies and interfere with each other.
2) bad-the range for the NIC's is ~300 feet outdoors, but last I checked, my whole network is in my house. the distance between my router and laptop in my bedroom=~80 feet and reception is like 20% (feels like I'm running 56k modem).
3) good-With the laptops, I can roam damn near anywhere in my house or take it out to the driveway to search for help while playing with car stuff.
With the routers, you can lock stuff down for security - encription and limiting DHCP pooling addresses (basically, limiting the amount of PC's being able to connect to your router.)
Hope this helps.
