comment Why does my Linksys WRT54G have three MAC addresses?
(1) Do you have ways to tell which is which? (2) It is not exactly "The MAC displayed near the IP 192.168.1.1 ". 192.168.1.1 is the IP of the router, and I connect to it on my computer to configure the router. its webpage shows a MAC address.

do you mean that the MAC address shown in 192.168.1.1 is for WLAN, while the one on the bottom of router is for LAN? Why is that?

comment Which device can create a new network?
Thanks. (1) by "Ethernet ports", do you mean the same as LAN ports? (2) what makes pluging into an Ethernet port of a router not create a new network, while plugging into a WAN port of a router does? Is it whether the router assigns internal IP to computers directly connected to the router?

@Immanuel: Thanks. What makes a router create a new network, while a switch or access point can't?

comment Why does my Linksys WRT54G have three MAC addresses?
my computer has a wireless adapter and a wired adapter. Are their "HWaddr" called their "Mac addresses"?

I ran them on my computer. Whose MAC address is "HWaddr" for?

What do "HWaddr" in the output of ifconfig mean? They are different from the three I mentioned at first.

comment Why does my Linksys WRT54G have three MAC addresses?
Thanks. I added the output of ifconfig. In its output, are "HWaddr" for some components of router, or for my computer's network adapters?

comment Which layer of network stack does access point operate?
Thanks. WHy doesn't a AP operate just in layer 1 but in 2? A link it says "In a sense, it's very much like a hub in that it pays no attention to the data that crosses it - it simply sends everything that it receives on a wired connection to the wireless transmitter and everything that it receives wirelessly is sent to the wired connection." The book says hub operates in layer 1.

@heavyd: Thanks. Is the following a necessary condition for being a network: in a network, must every connected machine be assigned an internal IP?

comment Relation between wireless network's frequency, speed, and range?
Do you call the freq range from 2.412GHz to 2.462GHz (offered as channel options in my router) "a 2.4GHz spec"?

comment Relation between wireless network's frequency, speed, and range?
" if an N router is configured for B/G/N it will only operate in 2.4GHz. Most routers can only operate at one frequency for all connections, so if you allow a 2.4GHz spec on your network, then it has to run everything at 2.4." My router is G router (supports G, B and their mix). Its channel options vary from channel 1 (2.412GHz) to 11 (2.462GHz), doesn't it not just operate on one frequency?

comment Relation between wireless network's frequency, speed, and range?
Thanks. (1) My router is linksys WRT54GL. Its options for channel are 1 (2.412GHz) to 11 (2.462GHz). Does it mean that the router will not create a wireless network with 5GHz? (2) My router supports "Mixed", "B-only" and "G-only" network mode. Is 5GHz only supported by 802.11a, not by 802.11b or 802.11g?
