Again, since all the units adhere to the 802.11b standard you are not getting anything 'extra' worth having by buying competing access points. Mine currently sits on top of a filing cabinet which has the bonus of being close to the ceiling. The 802.11b standard is supposed to be capable of 11mbs with a range of 100-150m. Naturally, this is the 'perfect' world environment. If you have a larger home, or cement walls, range extender atennas are available which the ASAP is capable of sending and recieving signals from.
Some experimentation is necessary in order to get 'best' coverage.
The default configuration has the Ethernet port of the ASAP set to be a DHCP client, this worked very well for me since the router I had it connected to served as my DHCP server. If you wish to change the default configuration however, the installation CD is available. Software drivers and client programs are also available for buffalo's LAN cards, but for security reasons I chose to use Lucent's Orinoco wireless cards instead of buffalo's. As I said, since 802.11b is a standard, you don't need to buy your networking hardware from the same company. In my mind the closing selling point of this product is its price - put simply, you are wasting your money if you buy an access point from any other company.
