The speeds I refer to are the speeds the wifi transmit's the signal between devices, it depends which protocol the router and the corresponding device your pc is using support. IEE 802.11a and 802.11b are older ones, 802.11g and 802.11g+ are newer. I forget what speeds they each are but I'm sure the newer ones are certainly as fast as the 10Mbps the net is provided at to the modem but in case anyone has older devices, say if a friend visits with a laptop and that has an 802.11b card, you might like to make sure the router is backwards compatible.
Not the greatest picture but you get the idea. Wifi devices tend to be PCI internal cards or USB devices.
MAC filtering - should say on the box but otherwise googling the model of router would likely be able to tell. What it is is registering each network devices (e.g. the network card on a desktop's motherboard or a wifi stick/card - basically network card connection to your network, wifi or wired) unique network address (MAC address) with the router so it will only let the approved devices connect to it, makes it a bit harder for anyone hacking your wifi network.
That's not fool proof though so also why WEP encryption is handy, much stronger than the previously recommended WAP encryption. You have a passkey for WEP that you need to tell your PC/device when setting up a connection - if you tell it to remember it then it won't ask each time it connects. :)
Any other questions or further clarification I'm happy to help.

And yeah PCI is inside desktop pc's - looks like...
