My husbands work computer doesn't have a MAC address on the bottom of it, so I wasn't able to set up the MAC address filtering on our home wireless network. Is there some other way to get the MAC address?
If we have to go without using MAC address filtering - how much of a security risk that? (we don't broadcast the SSID and use WPA2).
And one more question about MAC addresses - on my laptop and my husband's personal one there were 2 different MAC addresses on the bottom. Apparently I guessed right with which one to use, but why is there 2 and how to you determine (without just guessing) which is the correct one?
